Returns the web ACL capacity unit (WCU) requirements for a specified scope and set of rules. You can use this to check the capacity requirements for the rules you want to use in a RuleGroup or WebACL .
AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

string
[REQUIRED]
Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an API Gateway REST API, or an AppSync GraphQL API.
To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:
CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
API and SDKs - For all calls, use the Region endpoint us-east-1.
list
[REQUIRED]
An array of Rule that you're configuring to use in a rule group or web ACL.
(dict) --
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
Name (string) -- [REQUIRED]
The name of the rule. You can't change the name of a Rule after you create it.
Priority (integer) -- [REQUIRED]
If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.
Statement (dict) -- [REQUIRED]
The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) -- [REQUIRED]
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) -- [REQUIRED]
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
RuleGroupReferenceStatement (dict) --
A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.
You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) -- [REQUIRED]
The name of the rule to exclude.
IPSetReferenceStatement (dict) --
A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .
Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the IPSet that this statement references.
IPSetForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
Position (string) -- [REQUIRED]
The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) -- [REQUIRED]
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) -- [REQUIRED]
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) -- [REQUIRED]
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) -- [REQUIRED]
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) -- [REQUIRED]
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) -- [REQUIRED]
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) -- [REQUIRED]
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
AndStatement (dict) --

ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) -- [REQUIRED]
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) -- [REQUIRED]
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) -- [REQUIRED]
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) -- [REQUIRED]
Specify whether you want to match using the label name or just the namespace.
Key (string) -- [REQUIRED]
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
Action (dict) --
The action that AWS WAF should take on a web request when it matches the rule statement. Settings at the web ACL level can override the rule action setting.
This is used only for rules whose statements do not reference a rule group. Rule statements that reference a rule group include RuleGroupReferenceStatement and ManagedRuleGroupStatement .
You must specify either this Action setting or the rule OverrideAction setting, but not both:
If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this action setting.
Block (dict) --

CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.
ResponseHeaders (list) --
The HTTP headers to use in the response. Duplicate header names are not allowed.

Creates a RuleGroup per the specifications provided.
A rule group defines a collection of rules to inspect and control web requests that you can use in a WebACL . When you create a rule group, you define an immutable capacity limit. If you update a rule group, you must stay within the capacity. This allows others to reuse the rule group with confidence in its capacity requirements.

string
[REQUIRED]
The name of the rule group. You cannot change the name of a rule group after you create it.
string
[REQUIRED]
Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an API Gateway REST API, or an AppSync GraphQL API.
To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:
CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
API and SDKs - For all calls, use the Region endpoint us-east-1.
integer
[REQUIRED]
The web ACL capacity units (WCUs) required for this rule group.
When you create your own rule group, you define this, and you cannot change it after creation. When you add or modify the rules in a rule group, AWS WAF enforces this limit. You can check the capacity for a set of rules using CheckCapacity .
AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.
string
A description of the rule group that helps with identification.
list
The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
(dict) --
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
Name (string) -- [REQUIRED]
The name of the rule. You can't change the name of a Rule after you create it.
Priority (integer) -- [REQUIRED]
If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.
Statement (dict) -- [REQUIRED]
The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) -- [REQUIRED]
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) -- [REQUIRED]
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) -- [REQUIRED]
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) -- [REQUIRED]
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.
FieldToMatch (dict) -- [REQUIRED]

If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
Position (string) -- [REQUIRED]
The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) -- [REQUIRED]
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) -- [REQUIRED]
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) -- [REQUIRED]
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) -- [REQUIRED]
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) -- [REQUIRED]
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) -- [REQUIRED]
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) -- [REQUIRED]
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
AndStatement (dict) --

A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) -- [REQUIRED]
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) -- [REQUIRED]
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) -- [REQUIRED]
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) -- [REQUIRED]
Specify whether you want to match using the label name or just the namespace.
Key (string) -- [REQUIRED]
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
Action (dict) --
The action that AWS WAF should take on a web request when it matches the rule statement. Settings at the web ACL level can override the rule action setting.
This is used only for rules whose statements do not reference a rule group. Rule statements that reference a rule group include RuleGroupReferenceStatement and ManagedRuleGroupStatement .
You must specify either this Action setting or the rule OverrideAction setting, but not both:
If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this action setting.
Block (dict) --

CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.
ResponseHeaders (list) --
The HTTP headers to use in the response. Duplicate header names are not allowed.

RuleLabels (list) --
Labels to apply to web requests that match the rule match statement. AWS WAF applies fully qualified labels to matching web requests. A fully qualified label is the concatenation of a label namespace and a rule label. The rule's rule group or web ACL defines the label namespace.
Rules that run after this rule in the web ACL can match against these labels using a LabelMatchStatement .
For each label, provide a case-sensitive string containing optional namespaces and a label name, according to the following guidelines:
Separate each component of the label with a colon.
Each namespace or name can have up to 128 characters.
You can specify up to 5 namespaces in a label.

Response Structure
(dict) --
Summary (dict) --
High-level information about a RuleGroup , returned by operations like create and list. This provides information like the ID, that you can use to retrieve and manage a RuleGroup , and the ARN, that you provide to the RuleGroupReferenceStatement to use the rule group in a Rule .
Name (string) --
The name of the data type instance. You cannot change the name after you create the instance.
Id (string) --
A unique identifier for the rule group. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.
Description (string) --
A description of the rule group that helps with identification.
LockToken (string) --
A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.

Creates a WebACL per the specifications provided.
A Web ACL defines a collection of rules to use to inspect and control web requests. Each rule has an action defined (allow, block, or count) for requests that match the statement of the rule. In the Web ACL, you assign a default action to take (allow, block) for any request that does not match any of the rules. The rules in a Web ACL can be a combination of the types Rule , RuleGroup , and managed rule group. You can associate a Web ACL with one or more AWS resources to protect. The resources can be Amazon CloudFront, an Amazon API Gateway REST API, an Application Load Balancer, or an AWS AppSync GraphQL API.

string
[REQUIRED]
The name of the Web ACL. You cannot change the name of a Web ACL after you create it.
string
[REQUIRED]
Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an API Gateway REST API, or an AppSync GraphQL API.
To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:
CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
API and SDKs - For all calls, use the Region endpoint us-east-1.
dict
[REQUIRED]
The action to perform if none of the Rules contained in the WebACL match.
Block (dict) --
Specifies that AWS WAF should block requests by default.
CustomResponse (dict) --
Defines a custom response for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
ResponseCode (integer) -- [REQUIRED]
The HTTP status code to return to the client.
For a list of status codes that you can use in your custom reqponses, see Supported status codes for custom response in the AWS WAF Developer Guide .
CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.
ResponseHeaders (list) --
The HTTP headers to use in the response. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) -- [REQUIRED]
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) -- [REQUIRED]
The value of the custom header.
Allow (dict) --
Specifies that AWS WAF should allow requests by default.
CustomRequestHandling (dict) --
Defines custom handling for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
InsertHeaders (list) -- [REQUIRED]
The HTTP headers to insert into the request. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) -- [REQUIRED]
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) -- [REQUIRED]
The value of the custom header.
string
A description of the Web ACL that helps with identification.
list
The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
(dict) --
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
Name (string) -- [REQUIRED]
The name of the rule. You can't change the name of a Rule after you create it.
Priority (integer) -- [REQUIRED]
If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.
Statement (dict) -- [REQUIRED]
The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) -- [REQUIRED]
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.

QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

(string) --
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
RuleGroupReferenceStatement (dict) --
A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.
You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) -- [REQUIRED]
The name of the rule to exclude.
IPSetReferenceStatement (dict) --
A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .
Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the IPSet that this statement references.
IPSetForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
Position (string) -- [REQUIRED]
The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) -- [REQUIRED]
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) -- [REQUIRED]
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) -- [REQUIRED]
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) -- [REQUIRED]
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) -- [REQUIRED]
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) -- [REQUIRED]
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) -- [REQUIRED]
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --

ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .

FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.

ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) -- [REQUIRED]
Specify whether you want to match using the label name or just the namespace.
Key (string) -- [REQUIRED]
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
Action (dict) --
The action that AWS WAF should take on a web request when it matches the rule statement. Settings at the web ACL level can override the rule action setting.
This is used only for rules whose statements do not reference a rule group. Rule statements that reference a rule group include RuleGroupReferenceStatement and ManagedRuleGroupStatement .
You must specify either this Action setting or the rule OverrideAction setting, but not both:
If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this action setting.
Block (dict) --

A description of the Web ACL that helps with identification.
LockToken (string) --
A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.

Response Structure
(dict) --
Capacity (integer) --
The web ACL capacity units (WCUs) required for this rule group. AWS WAF uses web ACL capacity units (WCU) to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect each rule's relative cost. Rule group capacity is fixed at creation, so users can plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.
Rules (list) --
(dict) --
High-level information about a Rule , returned by operations like DescribeManagedRuleGroup . This provides information like the ID, that you can use to retrieve and manage a RuleGroup , and the ARN, that you provide to the RuleGroupReferenceStatement to use the rule group in a Rule .
Name (string) --
The name of the rule.
Action (dict) --
The action that AWS WAF should take on a web request when it matches a rule's statement. Settings at the web ACL level can override the rule action setting.
Block (dict) --
Instructs AWS WAF to block the web request.
CustomResponse (dict) --
Defines a custom response for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
ResponseCode (integer) --
The HTTP status code to return to the client.
For a list of status codes that you can use in your custom reqponses, see Supported status codes for custom response in the AWS WAF Developer Guide .
CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.
ResponseHeaders (list) --
The HTTP headers to use in the response. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.

(dict) --
LoggingConfiguration (dict) --
The LoggingConfiguration for the specified web ACL.
ResourceArn (string) --
The Amazon Resource Name (ARN) of the web ACL that you want to associate with LogDestinationConfigs .
LogDestinationConfigs (list) --
The Amazon Kinesis Data Firehose Amazon Resource Name (ARNs) that you want to associate with the web ACL.
(string) --
RedactedFields (list) --
The parts of the request that you want to keep out of the logs. For example, if you redact the HEADER field, the HEADER field in the firehose will be xxx .
Note
You must use one of the following values: URI , QUERY_STRING , HEADER , or METHOD .
(dict) --
The part of a web request that you want AWS WAF to inspect. Include the single FieldToMatch type that you want to inspect, with additional specifications as needed, according to the type. You specify a single request component in FieldToMatch for each rule statement that requires it. To inspect more than one component of a web request, create a separate rule statement for each component.
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) --
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) --
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
ManagedByFirewallManager (boolean) --
Indicates whether the logging configuration was created by AWS Firewall Manager, as part of an AWS WAF policy configuration. If true, only Firewall Manager can modify or delete the configuration.
LoggingFilter (dict) --
Filtering that specifies which web requests are kept in the logs and which are dropped. You can filter on the rule action and on the web request labels that were applied by matching rules during web ACL evaluation.
Filters (list) --
The filters that you want to apply to the logs.
(dict) --
A single logging filter, used in LoggingFilter .
Behavior (string) --
How to handle logs that satisfy the filter's conditions and requirement.
Requirement (string) --
Logic to apply to the filtering conditions. You can specify that, in order to satisfy the filter, a log must match all conditions or must match at least one condition.
Conditions (list) --
Match conditions for the filter.
(dict) --
A single match condition for a Filter .
ActionCondition (dict) --
A single action condition.
Action (string) --
The action setting that a log record must contain in order to meet the condition.
LabelNameCondition (dict) --
A single label name condition.
LabelName (string) --
The label name that a log record must contain in order to meet the condition. This must be a fully qualified label name. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label.
DefaultBehavior (string) --
Default handling for logs that don't match any of the specified filtering conditions.

Response Structure
(dict) --
RuleGroup (dict) --
Name (string) --
The name of the rule group. You cannot change the name of a rule group after you create it.
Id (string) --
A unique identifier for the rule group. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.
Capacity (integer) --
The web ACL capacity units (WCUs) required for this rule group.
When you create your own rule group, you define this, and you cannot change it after creation. When you add or modify the rules in a rule group, AWS WAF enforces this limit. You can check the capacity for a set of rules using CheckCapacity .
AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.
Description (string) --
A description of the rule group that helps with identification.
Rules (list) --
The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
(dict) --
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
Name (string) --
The name of the rule. You can't change the name of a Rule after you create it.
Priority (integer) --
If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.
Statement (dict) --
The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) --
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) --
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) --
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) --
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
PositionalConstraint (string) --
The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:
CONTAINS
The specified part of the web request must include the value of SearchString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:
SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of SearchString .
STARTS_WITH
The value of SearchString must appear at the beginning of the specified part of the web request.
ENDS_WITH
The value of SearchString must appear at the end of the specified part of the web request.
SqliMatchStatement (dict) --
Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) --
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .

MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

Name (string) --
The name of the rule to exclude.
IPSetReferenceStatement (dict) --
A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .
Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) --
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) --
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) --
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
AndStatement (dict) --
A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .
Statements (list) --
The statements to combine with AND logic. You can use any statements that can be nested.

Statement (dict) --
The statement to negate. You can use any statement that can be nested.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) --
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) --
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) --
Specify whether you want to match using the label name or just the namespace.
Key (string) --
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
Action (dict) --
The action that AWS WAF should take on a web request when it matches the rule statement. Settings at the web ACL level can override the rule action setting.
This is used only for rules whose statements do not reference a rule group. Rule statements that reference a rule group include RuleGroupReferenceStatement and ManagedRuleGroupStatement .
You must specify either this Action setting or the rule OverrideAction setting, but not both:
If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this action setting.
Block (dict) --

Rules that run after this rule in the web ACL can match against these labels using a LabelMatchStatement .
For each label, provide a case-sensitive string containing optional namespaces and a label name, according to the following guidelines:
Separate each component of the label with a colon.
Each namespace or name can have up to 128 characters.
You can specify up to 5 namespaces in a label.

Name (string) --
An individual label specification.
LockToken (string) --
A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.
{'SampledRequests': {'Labels': [{'Name': 'string'}]}}
Gets detailed information about a specified number of requests--a sample--that AWS WAF randomly selects from among the first 5,000 requests that your AWS resource received during a time range that you choose. You can specify a sample size of up to 500 requests, and you can specify any time range in the previous three hours.
GetSampledRequests returns a time range, which is usually the time range that you specified. However, if your resource (such as a CloudFront distribution) received 5,000 requests before the specified time range elapsed, GetSampledRequests returns an updated time range. This new time range indicates the actual period during which AWS WAF selected the requests in the sample.

Response Structure
(dict) --
WebACL (dict) --
The Web ACL specification. You can modify the settings in this Web ACL and use it to update this Web ACL or create a new one.
Name (string) --
The name of the Web ACL. You cannot change the name of a Web ACL after you create it.
Id (string) --
A unique identifier for the WebACL . This ID is returned in the responses to create and list commands. You use this ID to do things like get, update, and delete a WebACL .
ARN (string) --
The Amazon Resource Name (ARN) of the Web ACL that you want to associate with the resource.
DefaultAction (dict) --
The action to perform if none of the Rules contained in the WebACL match.
Block (dict) --
Specifies that AWS WAF should block requests by default.
CustomResponse (dict) --
Defines a custom response for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
ResponseCode (integer) --
The HTTP status code to return to the client.
For a list of status codes that you can use in your custom reqponses, see Supported status codes for custom response in the AWS WAF Developer Guide .
CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.
ResponseHeaders (list) --
The HTTP headers to use in the response. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.
Allow (dict) --
Specifies that AWS WAF should allow requests by default.
CustomRequestHandling (dict) --
Defines custom handling for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
InsertHeaders (list) --
The HTTP headers to insert into the request. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.
Description (string) --
A description of the Web ACL that helps with identification.
Rules (list) --
The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
(dict) --
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
Name (string) --
The name of the rule. You can't change the name of a Rule after you create it.
Priority (integer) --
If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.
Statement (dict) --
The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) --
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) --
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) --
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) --
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
PositionalConstraint (string) --
The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:
CONTAINS
The specified part of the web request must include the value of SearchString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:
SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of SearchString .
STARTS_WITH
The value of SearchString must appear at the beginning of the specified part of the web request.
ENDS_WITH
The value of SearchString must appear at the end of the specified part of the web request.
SqliMatchStatement (dict) --
Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.
FieldToMatch (dict) --

InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.

If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.

RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) --
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) --
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) --
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
AndStatement (dict) --
A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .

You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) --
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) --
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --

Name (string) --
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) --
Specify whether you want to match using the label name or just the namespace.
Key (string) --
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
Action (dict) --
The action that AWS WAF should take on a web request when it matches the rule statement. Settings at the web ACL level can override the rule action setting.
This is used only for rules whose statements do not reference a rule group. Rule statements that reference a rule group include RuleGroupReferenceStatement and ManagedRuleGroupStatement .
You must specify either this Action setting or the rule OverrideAction setting, but not both:
If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this action setting.

Rules that run after this rule in the web ACL can match against these labels using a LabelMatchStatement .
For each label, provide a case-sensitive string containing optional namespaces and a label name, according to the following guidelines:
Separate each component of the label with a colon.
Each namespace or name can have up to 128 characters.
You can specify up to 5 namespaces in a label.
Don't use the following reserved words in your label specification: aws , waf , managed , rulegroup , webacl , regexpatternset , or ipset .
For example, myLabelName or nameSpace1:nameSpace2:myLabelName .
(dict) --
A single label container. This is used as an element of a label array in multiple contexts, for example, in RuleLabels inside a Rule and in Labels inside a SampledHTTPRequest .

A name of the CloudWatch metric. The name can contain only the characters: A-Z, a-z, 0-9, - (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action."
Capacity (integer) --
The web ACL capacity units (WCUs) currently being used by this web ACL.
AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.
PreProcessFirewallManagerRuleGroups (list) --
The first set of rules for AWS WAF to process in the web ACL. This is defined in an AWS Firewall Manager WAF policy and contains only rule group references. You can't alter these. Any rules and rule groups that you define for the web ACL are prioritized after these.
In the Firewall Manager WAF policy, the Firewall Manager administrator can define a set of rule groups to run first in the web ACL and a set of rule groups to run last. Within each set, the administrator prioritizes the rule groups, to determine their relative processing order.
(dict) --
A rule group that's defined for an AWS Firewall Manager WAF policy.
Name (string) --
The name of the rule group. You cannot change the name of a rule group after you create it.
Priority (integer) --
If you define more than one rule group in the first or last Firewall Manager rule groups, AWS WAF evaluates each request against the rule groups in order, starting from the lowest priority setting. The priorities don't need to be consecutive, but they must all be different.
FirewallManagerStatement (dict) --
The processing guidance for an AWS Firewall Manager rule. This is like a regular rule Statement , but it can only contain a rule group reference.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) --
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) --
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.

Name (string) --
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) --
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }

SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) --
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >

Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
PositionalConstraint (string) --
The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:
CONTAINS
The specified part of the web request must include the value of SearchString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:
SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of SearchString .

SqliMatchStatement (dict) --
Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.
FieldToMatch (dict) --

SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --

Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}

You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

NO_MATCH - Treat the web request as not matching the rule statement.
Position (string) --
The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) --
The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) --
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) --
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) --
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
AndStatement (dict) --
A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .
Statements (list) --
The statements to combine with AND logic. You can use any statements that can be nested.
(dict) --

Statement (dict) --
The statement to negate. You can use any statement that can be nested.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) --
Specify whether you want to match using the label name or just the namespace.
Key (string) --
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
RuleGroupReferenceStatement (dict) --
A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.
You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) --

ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
OverrideAction (dict) --
The override action to apply to the rules in a rule group. Used only for rule statements that reference a rule group, like RuleGroupReferenceStatement and ManagedRuleGroupStatement .
Set the override action to none to leave the rule actions in effect. Set it to count to only count matches, regardless of the rule action settings.
In a Rule , you must specify either this OverrideAction setting or the rule Action setting, but not both:
If the rule statement references a rule group, use this override action setting and not the action setting.
If the rule statement does not reference a rule group, use the rule action setting and not this rule override action setting.
Count (dict) --
Override the rule action setting to count.

(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.
None (dict) --
Don't override the rule action setting.
VisibilityConfig (dict) --
Defines and enables Amazon CloudWatch metrics and web request sample collection.
SampledRequestsEnabled (boolean) --
A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.
CloudWatchMetricsEnabled (boolean) --
A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .
MetricName (string) --
A name of the CloudWatch metric. The name can contain only the characters: A-Z, a-z, 0-9, - (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action."
PostProcessFirewallManagerRuleGroups (list) --
The last set of rules for AWS WAF to process in the web ACL. This is defined in an AWS Firewall Manager WAF policy and contains only rule group references. You can't alter these. Any rules and rule groups that you define for the web ACL are prioritized before these.
In the Firewall Manager WAF policy, the Firewall Manager administrator can define a set of rule groups to run first in the web ACL and a set of rule groups to run last. Within each set, the administrator prioritizes the rule groups, to determine their relative processing order.
(dict) --
A rule group that's defined for an AWS Firewall Manager WAF policy.
Name (string) --
The name of the rule group. You cannot change the name of a rule group after you create it.
Priority (integer) --
If you define more than one rule group in the first or last Firewall Manager rule groups, AWS WAF evaluates each request against the rule groups in order, starting from the lowest priority setting. The priorities don't need to be consecutive, but they must all be different.
FirewallManagerStatement (dict) --
The processing guidance for an AWS Firewall Manager rule. This is like a regular rule Statement , but it can only contain a rule group reference.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) --
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) --
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) --
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) --

The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.

You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --

RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) --

This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .

NotStatement (dict) --
A logical rule statement used to negate the results of another rule statement. You provide one Statement within the NotStatement .
Statement (dict) --
The statement to negate. You can use any statement that can be nested.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) --
Specify whether you want to match using the label name or just the namespace.
Key (string) --
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
RuleGroupReferenceStatement (dict) --
A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.
You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
OverrideAction (dict) --
The override action to apply to the rules in a rule group. Used only for rule statements that reference a rule group, like RuleGroupReferenceStatement and ManagedRuleGroupStatement .
Set the override action to none to leave the rule actions in effect. Set it to count to only count matches, regardless of the rule action settings.
In a Rule , you must specify either this OverrideAction setting or the rule Action setting, but not both:
If the rule statement references a rule group, use this override action setting and not the action setting.
If the rule statement does not reference a rule group, use the rule action setting and not this rule override action setting.
Count (dict) --
Override the rule action setting to count.
CustomRequestHandling (dict) --
Defines custom handling for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
InsertHeaders (list) --
The HTTP headers to insert into the request. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.
None (dict) --
Don't override the rule action setting.
VisibilityConfig (dict) --
Defines and enables Amazon CloudWatch metrics and web request sample collection.
SampledRequestsEnabled (boolean) --
A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.
CloudWatchMetricsEnabled (boolean) --
A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .
MetricName (string) --
A name of the CloudWatch metric. The name can contain only the characters: A-Z, a-z, 0-9, - (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action."
ManagedByFirewallManager (boolean) --
Indicates whether this web ACL is managed by AWS Firewall Manager. If true, then only AWS Firewall Manager can delete the web ACL or any Firewall Manager rule groups in the web ACL.
LabelNamespace (string) --
The label namespace prefix for this web ACL. All labels added by rules in this web ACL have this prefix.
The syntax for the label namespace prefix for a web ACL is the following: awswaf:<account ID>:webacl:<web ACL name>:
When a rule with a label matches a web request, AWS WAF adds the fully qualified label to the request. A fully qualified label is made up of the label namespace from the rule group or web ACL where the rule is defined and the label from the rule, separated by a colon: <label namespace>:<label from rule>
CustomResponseBodies (dict) --
A map of custom response keys and content bodies. When you create a rule with a block action, you can send a custom response to the web request. You define these for the web ACL, and then use them in the rules and default actions that you define in the web ACL.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(string) --
(dict) --
The response body to use in a custom response to a web request. This is referenced by key from CustomResponse CustomResponseBodyKey .
ContentType (string) --
The type of content in the payload that you are defining in the Content string.
Content (string) --
The payload of the custom response.
You can use JSON escape strings in JSON content. To do this, you must specify JSON content in the ContentType setting.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
LockToken (string) --
A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.

Response Structure
(dict) --
WebACL (dict) --
The Web ACL that is associated with the resource. If there is no associated resource, AWS WAF returns a null Web ACL.
Name (string) --
The name of the Web ACL. You cannot change the name of a Web ACL after you create it.
Id (string) --
A unique identifier for the WebACL . This ID is returned in the responses to create and list commands. You use this ID to do things like get, update, and delete a WebACL .
ARN (string) --
The Amazon Resource Name (ARN) of the Web ACL that you want to associate with the resource.
DefaultAction (dict) --
The action to perform if none of the Rules contained in the WebACL match.
Block (dict) --
Specifies that AWS WAF should block requests by default.
CustomResponse (dict) --
Defines a custom response for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
ResponseCode (integer) --
The HTTP status code to return to the client.
For a list of status codes that you can use in your custom reqponses, see Supported status codes for custom response in the AWS WAF Developer Guide .
CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.
ResponseHeaders (list) --
The HTTP headers to use in the response. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.
Allow (dict) --
Specifies that AWS WAF should allow requests by default.
CustomRequestHandling (dict) --
Defines custom handling for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
InsertHeaders (list) --
The HTTP headers to insert into the request. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.
Description (string) --
A description of the Web ACL that helps with identification.
Rules (list) --
The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
(dict) --
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
Name (string) --
The name of the rule. You can't change the name of a Rule after you create it.
Priority (integer) --
If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.
Statement (dict) --
The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) --
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) --
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) --
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .

(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.

The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
IPSetReferenceStatement (dict) --
A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .
Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) --
The Amazon Resource Name (ARN) of the IPSet that this statement references.
IPSetForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) --
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
Position (string) --
The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) --
The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) --
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) --
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) --
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) --
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) --
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --

ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) --
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
AndStatement (dict) --

ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) --
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) --
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --

The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) --
Specify whether you want to match using the label name or just the namespace.
Key (string) --
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
Action (dict) --
The action that AWS WAF should take on a web request when it matches the rule statement. Settings at the web ACL level can override the rule action setting.
This is used only for rules whose statements do not reference a rule group. Rule statements that reference a rule group include RuleGroupReferenceStatement and ManagedRuleGroupStatement .
You must specify either this Action setting or the rule OverrideAction setting, but not both:
If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this action setting.
Block (dict) --

Rules that run after this rule in the web ACL can match against these labels using a LabelMatchStatement .
For each label, provide a case-sensitive string containing optional namespaces and a label name, according to the following guidelines:
Separate each component of the label with a colon.
Each namespace or name can have up to 128 characters.
You can specify up to 5 namespaces in a label.
Don't use the following reserved words in your label specification: aws , waf , managed , rulegroup , webacl , regexpatternset , or ipset .
For example, myLabelName or nameSpace1:nameSpace2:myLabelName .
(dict) --

Capacity (integer) --
The web ACL capacity units (WCUs) currently being used by this web ACL.
AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.
PreProcessFirewallManagerRuleGroups (list) --
The first set of rules for AWS WAF to process in the web ACL. This is defined in an AWS Firewall Manager WAF policy and contains only rule group references. You can't alter these. Any rules and rule groups that you define for the web ACL are prioritized after these.
In the Firewall Manager WAF policy, the Firewall Manager administrator can define a set of rule groups to run first in the web ACL and a set of rule groups to run last. Within each set, the administrator prioritizes the rule groups, to determine their relative processing order.
(dict) --
A rule group that's defined for an AWS Firewall Manager WAF policy.
Name (string) --
The name of the rule group. You cannot change the name of a rule group after you create it.
Priority (integer) --
If you define more than one rule group in the first or last Firewall Manager rule groups, AWS WAF evaluates each request against the rule groups in order, starting from the lowest priority setting. The priorities don't need to be consecutive, but they must all be different.
FirewallManagerStatement (dict) --
The processing guidance for an AWS Firewall Manager rule. This is like a regular rule Statement , but it can only contain a rule group reference.
ManagedRuleGroupStatement (dict) --

Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) --
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .

Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service.

InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --

If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) --
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
RuleGroupReferenceStatement (dict) --
A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.
You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
IPSetReferenceStatement (dict) --
A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .
Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) --
The Amazon Resource Name (ARN) of the IPSet that this statement references.
IPSetForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) --
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
Position (string) --
The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) --
The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) --
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) --
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) --
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) --
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) --
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .

ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) --
Specify whether you want to match using the label name or just the namespace.
Key (string) --
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
RuleGroupReferenceStatement (dict) --
A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
OverrideAction (dict) --
The override action to apply to the rules in a rule group. Used only for rule statements that reference a rule group, like RuleGroupReferenceStatement and ManagedRuleGroupStatement .
Set the override action to none to leave the rule actions in effect. Set it to count to only count matches, regardless of the rule action settings.
In a Rule , you must specify either this OverrideAction setting or the rule Action setting, but not both:
If the rule statement references a rule group, use this override action setting and not the action setting.
If the rule statement does not reference a rule group, use the rule action setting and not this rule override action setting.
Count (dict) --

Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.
None (dict) --
Don't override the rule action setting.
VisibilityConfig (dict) --
Defines and enables Amazon CloudWatch metrics and web request sample collection.
SampledRequestsEnabled (boolean) --
A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.
CloudWatchMetricsEnabled (boolean) --
A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .
MetricName (string) --
A name of the CloudWatch metric. The name can contain only the characters: A-Z, a-z, 0-9, - (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action."
PostProcessFirewallManagerRuleGroups (list) --
The last set of rules for AWS WAF to process in the web ACL. This is defined in an AWS Firewall Manager WAF policy and contains only rule group references. You can't alter these. Any rules and rule groups that you define for the web ACL are prioritized before these.
In the Firewall Manager WAF policy, the Firewall Manager administrator can define a set of rule groups to run first in the web ACL and a set of rule groups to run last. Within each set, the administrator prioritizes the rule groups, to determine their relative processing order.
(dict) --

FirewallManagerStatement (dict) --
The processing guidance for an AWS Firewall Manager rule. This is like a regular rule Statement , but it can only contain a rule group reference.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) --
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) --
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --

Name (string) --
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) --
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

PositionalConstraint (string) --
The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:
CONTAINS
The specified part of the web request must include the value of SearchString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:
SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of SearchString .

ENDS_WITH
The value of SearchString must appear at the end of the specified part of the web request.
SqliMatchStatement (dict) --
Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) --

Name (string) --
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.

MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.

A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.
You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.

Name (string) --
The name of the rule to exclude.
IPSetReferenceStatement (dict) --
A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet .
Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) --
The Amazon Resource Name (ARN) of the IPSet that this statement references.
IPSetForwardedIPConfig (dict) --

MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
Position (string) --
The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through.
The options for this setting are the following:
FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client's original IP.
LAST - Inspect the last IP address in the list of IP addresses in the header.
ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, AWS WAF inspects the last 10.
RegexPatternSetReferenceStatement (dict) --
A rule statement used to search web request components for matches with regular expressions. To use this, create a RegexPatternSet that specifies the expressions that you want to detect, then use the ARN of that set in this statement. A web request matches the pattern set rule statement if the request component matches any of the patterns in the set. To create a regex pattern set, see CreateRegexPatternSet .
Each regex pattern set rule statement references a regex pattern set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, AWS WAF automatically updates all rules that reference it.
ARN (string) --
The Amazon Resource Name (ARN) of the RegexPatternSet that this statement references.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) --
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) --
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) --
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) --
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) --
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) --
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) --
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) --
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
AndStatement (dict) --
A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .
Statements (list) --
The statements to combine with AND logic. You can use any statements that can be nested.
(dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
OrStatement (dict) --
A logical rule statement used to combine other rule statements with OR logic. You provide more than one Statement within the OrStatement .
Statements (list) --
The statements to combine with OR logic. You can use any statements that can be nested.
(dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
NotStatement (dict) --
A logical rule statement used to negate the results of another rule statement. You provide one Statement within the NotStatement .
Statement (dict) --
The statement to negate. You can use any statement that can be nested.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) --
Specify whether you want to match using the label name or just the namespace.
Key (string) --
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
RuleGroupReferenceStatement (dict) --
A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.
You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
ARN (string) --
The Amazon Resource Name (ARN) of the entity.
ExcludedRules (list) --
The names of rules that are in the referenced rule group, but that you want AWS WAF to exclude from processing for this rule statement.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) --
The name of the rule to exclude.
OverrideAction (dict) --
The override action to apply to the rules in a rule group. Used only for rule statements that reference a rule group, like RuleGroupReferenceStatement and ManagedRuleGroupStatement .
Set the override action to none to leave the rule actions in effect. Set it to count to only count matches, regardless of the rule action settings.
In a Rule , you must specify either this OverrideAction setting or the rule Action setting, but not both:
If the rule statement references a rule group, use this override action setting and not the action setting.
If the rule statement does not reference a rule group, use the rule action setting and not this rule override action setting.
Count (dict) --
Override the rule action setting to count.
CustomRequestHandling (dict) --
Defines custom handling for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
InsertHeaders (list) --
The HTTP headers to insert into the request. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) --
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) --
The value of the custom header.
None (dict) --
Don't override the rule action setting.
VisibilityConfig (dict) --
Defines and enables Amazon CloudWatch metrics and web request sample collection.
SampledRequestsEnabled (boolean) --
A boolean indicating whether AWS WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the AWS WAF console.
CloudWatchMetricsEnabled (boolean) --
A boolean indicating whether the associated resource sends metrics to CloudWatch. For the list of available metrics, see AWS WAF Metrics .
MetricName (string) --
A name of the CloudWatch metric. The name can contain only the characters: A-Z, a-z, 0-9, - (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can't contain whitespace or metric names reserved for AWS WAF, for example "All" and "Default_Action."
ManagedByFirewallManager (boolean) --
Indicates whether this web ACL is managed by AWS Firewall Manager. If true, then only AWS Firewall Manager can delete the web ACL or any Firewall Manager rule groups in the web ACL.
LabelNamespace (string) --
The label namespace prefix for this web ACL. All labels added by rules in this web ACL have this prefix.
The syntax for the label namespace prefix for a web ACL is the following: awswaf:<account ID>:webacl:<web ACL name>:
When a rule with a label matches a web request, AWS WAF adds the fully qualified label to the request. A fully qualified label is made up of the label namespace from the rule group or web ACL where the rule is defined and the label from the rule, separated by a colon: <label namespace>:<label from rule>
CustomResponseBodies (dict) --
A map of custom response keys and content bodies. When you create a rule with a block action, you can send a custom response to the web request. You define these for the web ACL, and then use them in the rules and default actions that you define in the web ACL.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(string) --
(dict) --
The response body to use in a custom response to a web request. This is referenced by key from CustomResponse CustomResponseBodyKey .
ContentType (string) --
The type of content in the payload that you are defining in the Content string.
Content (string) --
The payload of the custom response.
You can use JSON escape strings in JSON content. To do this, you must specify JSON content in the ContentType setting.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .

Enables the specified LoggingConfiguration , to start logging from a web ACL, according to the configuration provided.
You can access information about all traffic that AWS WAF inspects using the following steps:
Create an Amazon Kinesis Data Firehose. Create the data firehose with a PUT source and in the Region that you are operating. If you are capturing logs for Amazon CloudFront, always create the firehose in US East (N. Virginia). Give the data firehose a name that starts with the prefix aws-waf-logs- . For example, aws-waf-logs-us-east-2-analytics .
Note
Do not create the data firehose using a Kinesis stream as your source.
Associate that firehose to your web ACL using a PutLoggingConfiguration request.
When you successfully enable logging using a PutLoggingConfiguration request, AWS WAF will create a service linked role with the necessary permissions to write logs to the Amazon Kinesis Data Firehose. For more information, see Logging Web ACL Traffic Information in the AWS WAF Developer Guide .

To inspect more than one component of a web request, create a separate rule statement for each component.
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) -- [REQUIRED]
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) -- [REQUIRED]
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) -- [REQUIRED]
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
ManagedByFirewallManager (boolean) --
Indicates whether the logging configuration was created by AWS Firewall Manager, as part of an AWS WAF policy configuration. If true, only Firewall Manager can modify or delete the configuration.
LoggingFilter (dict) --
Filtering that specifies which web requests are kept in the logs and which are dropped. You can filter on the rule action and on the web request labels that were applied by matching rules during web ACL evaluation.
Filters (list) -- [REQUIRED]
The filters that you want to apply to the logs.
(dict) --
A single logging filter, used in LoggingFilter .
Behavior (string) -- [REQUIRED]
How to handle logs that satisfy the filter's conditions and requirement.
Requirement (string) -- [REQUIRED]
Logic to apply to the filtering conditions. You can specify that, in order to satisfy the filter, a log must match all conditions or must match at least one condition.
Conditions (list) -- [REQUIRED]
Match conditions for the filter.
(dict) --
A single match condition for a Filter .
ActionCondition (dict) --
A single action condition.
Action (string) -- [REQUIRED]
The action setting that a log record must contain in order to meet the condition.
LabelNameCondition (dict) --
A single label name condition.
LabelName (string) -- [REQUIRED]
The label name that a log record must contain in order to meet the condition. This must be a fully qualified label name. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label.
DefaultBehavior (string) -- [REQUIRED]
Default handling for logs that don't match any of the specified filtering conditions.

Updates the specified RuleGroup .
A rule group defines a collection of rules to inspect and control web requests that you can use in a WebACL . When you create a rule group, you define an immutable capacity limit. If you update a rule group, you must stay within the capacity. This allows others to reuse the rule group with confidence in its capacity requirements.

string
[REQUIRED]
The name of the rule group. You cannot change the name of a rule group after you create it.
string
[REQUIRED]
Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an API Gateway REST API, or an AppSync GraphQL API.
To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:
CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
API and SDKs - For all calls, use the Region endpoint us-east-1.
string
[REQUIRED]
A unique identifier for the rule group. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.
string
A description of the rule group that helps with identification.
list
The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
(dict) --
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
Name (string) -- [REQUIRED]
The name of the rule. You can't change the name of a Rule after you create it.
Priority (integer) -- [REQUIRED]
If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.
Statement (dict) -- [REQUIRED]
The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) -- [REQUIRED]
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) -- [REQUIRED]
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) -- [REQUIRED]
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) -- [REQUIRED]
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) -- [REQUIRED]
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) -- [REQUIRED]
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
PositionalConstraint (string) -- [REQUIRED]
The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:
CONTAINS
The specified part of the web request must include the value of SearchString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:
SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of SearchString .
STARTS_WITH
The value of SearchString must appear at the beginning of the specified part of the web request.
ENDS_WITH
The value of SearchString must appear at the end of the specified part of the web request.
SqliMatchStatement (dict) --
Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .

XssMatchStatement (dict) --
A rule statement that defines a cross-site scripting (XSS) match search for AWS WAF to apply to web requests. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a vehicle to inject malicious client-site scripts into other legitimate web browsers. The XSS match statement provides the location in requests that you want AWS WAF to search and text transformations to use on the search area before AWS WAF searches for character sequences that are likely to be malicious strings.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --

RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.

ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .

The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
OrStatement (dict) --
A logical rule statement used to combine other rule statements with OR logic. You provide more than one Statement within the OrStatement .
Statements (list) -- [REQUIRED]
The statements to combine with OR logic. You can use any statements that can be nested.
(dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
NotStatement (dict) --
A logical rule statement used to negate the results of another rule statement. You provide one Statement within the NotStatement .
Statement (dict) --
The statement to negate. You can use any statement that can be nested.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) -- [REQUIRED]
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) -- [REQUIRED]
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) -- [REQUIRED]
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) -- [REQUIRED]
Specify whether you want to match using the label name or just the namespace.
Key (string) -- [REQUIRED]
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
Action (dict) --
The action that AWS WAF should take on a web request when it matches the rule statement. Settings at the web ACL level can override the rule action setting.
This is used only for rules whose statements do not reference a rule group. Rule statements that reference a rule group include RuleGroupReferenceStatement and ManagedRuleGroupStatement .
You must specify either this Action setting or the rule OverrideAction setting, but not both:
If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this action setting.
Block (dict) --
Instructs AWS WAF to block the web request.
CustomResponse (dict) --
Defines a custom response for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .

For a list of status codes that you can use in your custom reqponses, see Supported status codes for custom response in the AWS WAF Developer Guide .
CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.
ResponseHeaders (list) --
The HTTP headers to use in the response. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .

RuleLabels (list) --
Labels to apply to web requests that match the rule match statement. AWS WAF applies fully qualified labels to matching web requests. A fully qualified label is the concatenation of a label namespace and a rule label. The rule's rule group or web ACL defines the label namespace.
Rules that run after this rule in the web ACL can match against these labels using a LabelMatchStatement .
For each label, provide a case-sensitive string containing optional namespaces and a label name, according to the following guidelines:
Separate each component of the label with a colon.
Each namespace or name can have up to 128 characters.
You can specify up to 5 namespaces in a label.
Don't use the following reserved words in your label specification: aws , waf , managed , rulegroup , webacl , regexpatternset , or ipset .
For example, myLabelName or nameSpace1:nameSpace2:myLabelName .

string
[REQUIRED]
A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.
dict
A map of custom response keys and content bodies. When you create a rule with a block action, you can send a custom response to the web request. You define these for the rule group, and then use them in the rules that you define in the rule group.

Updates the specified WebACL .
A Web ACL defines a collection of rules to use to inspect and control web requests. Each rule has an action defined (allow, block, or count) for requests that match the statement of the rule. In the Web ACL, you assign a default action to take (allow, block) for any request that does not match any of the rules. The rules in a Web ACL can be a combination of the types Rule , RuleGroup , and managed rule group. You can associate a Web ACL with one or more AWS resources to protect. The resources can be Amazon CloudFront, an Amazon API Gateway REST API, an Application Load Balancer, or an AWS AppSync GraphQL API.

string
[REQUIRED]
The name of the Web ACL. You cannot change the name of a Web ACL after you create it.
string
[REQUIRED]
Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an API Gateway REST API, or an AppSync GraphQL API.
To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:
CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .
API and SDKs - For all calls, use the Region endpoint us-east-1.
string
[REQUIRED]
The unique identifier for the Web ACL. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.
dict
[REQUIRED]
The action to perform if none of the Rules contained in the WebACL match.
Block (dict) --
Specifies that AWS WAF should block requests by default.
CustomResponse (dict) --
Defines a custom response for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .
ResponseCode (integer) -- [REQUIRED]
The HTTP status code to return to the client.
For a list of status codes that you can use in your custom reqponses, see Supported status codes for custom response in the AWS WAF Developer Guide .
CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.
ResponseHeaders (list) --
The HTTP headers to use in the response. Duplicate header names are not allowed.
For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .
(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) -- [REQUIRED]
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) -- [REQUIRED]
The value of the custom header.
Allow (dict) --
Specifies that AWS WAF should allow requests by default.
CustomRequestHandling (dict) --
Defines custom handling for the web request.
For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .

(dict) --
A custom header for custom request and response handling. This is used in CustomResponse and CustomRequestHandling .
Name (string) -- [REQUIRED]
The name of the custom header.
For custom request header insertion, when AWS WAF inserts the header into the request, it prefixes this name x-amzn-waf- , to avoid confusion with the headers that are already in the request. For example, for the header name sample , AWS WAF inserts the header x-amzn-waf-sample .
Value (string) -- [REQUIRED]
The value of the custom header.
string
A description of the Web ACL that helps with identification.
list
The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
(dict) --
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.
Name (string) -- [REQUIRED]
The name of the rule. You can't change the name of a Rule after you create it.
Priority (integer) -- [REQUIRED]
If you define more than one Rule in a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . AWS WAF processes rules with lower priority first. The priorities don't need to be consecutive, but they must all be different.
Statement (dict) -- [REQUIRED]
The AWS WAF processing statement for the rule, for example ByteMatchStatement or SizeConstraintStatement .
ByteMatchStatement (dict) --
A rule statement that defines a string match search for AWS WAF to apply to web requests. The byte match statement provides the bytes to search for, the location in requests that you want AWS WAF to search, and other settings. The bytes to search for are typically a string that corresponds with ASCII characters. In the AWS WAF console and the developer guide, this is refered to as a string match statement.
SearchString (bytes) -- [REQUIRED]
A string value that you want AWS WAF to search for. AWS WAF searches only in the part of web requests that you designate for inspection in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the component that you specify for inspection in FieldToMatch :
Method : The HTTP method that you want AWS WAF to search for. This indicates the type of operation specified in the request.
UriPath : The value that you want AWS WAF to search for in the URI path, for example, /images/daily-ad.jpg .
If SearchString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.
If you're using the AWS WAF API
Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.
For example, suppose the value of Type is HEADER and the value of Data is User-Agent . If you want to search the User-Agent header for the value BadBot , you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90 , in the value of SearchString .
If you're using the AWS CLI or one of the AWS SDKs
The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }
Name (string) -- [REQUIRED]
The name of the query header to inspect.
SingleQueryArgument (dict) --
Inspect a single query argument. Provide the name of the query argument to inspect, such as UserName or SalesRegion . The name can be up to 30 characters long and isn't case sensitive.
This is used only to indicate the web request component for AWS WAF to inspect, in the FieldToMatch specification.
Example JSON: "SingleQueryArgument": { "Name": "myArgument" }
Name (string) -- [REQUIRED]
The name of the query argument to inspect.
AllQueryArguments (dict) --
Inspect all query arguments.
UriPath (dict) --
Inspect the request URI path. This is the part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
QueryString (dict) --
Inspect the query string. This is the part of a URL that appears after a ? character, if any.
Body (dict) --
Inspect the request body as plain text. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
Method (dict) --
Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
JsonBody (dict) --
Inspect the request body as JSON. The request body immediately follows the request headers. This is the part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form.
Note that only the first 8 KB (8192 bytes) of the request body are forwarded to AWS WAF for inspection by the underlying host service. If you don't need to inspect more than 8 KB, you can guarantee that you don't allow additional bytes in by combining a statement that inspects the body of the web request, such as ByteMatchStatement or RegexPatternSetReferenceStatement , with a SizeConstraintStatement that enforces an 8 KB size limit on the body of the request. AWS WAF doesn't support inspecting the entire contents of web requests whose bodies exceed the 8 KB limit.
MatchPattern (dict) -- [REQUIRED]
The patterns to look for in the JSON body. AWS WAF inspects the results of these pattern matches against the rule inspection criteria.
All (dict) --
Match all of the elements. See also MatchScope in JsonBody .
You must specify either this setting or the IncludedPaths setting, but not both.
IncludedPaths (list) --
Match only the specified include paths. See also MatchScope in JsonBody .
Provide the include paths using JSON Pointer syntax. For example, "IncludedPaths": ["/dogs/0/name", "/dogs/1/name"] . For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer .
You must specify either this setting or the All setting, but not both.
Note
Don't use this option to include all paths. Instead, use the All setting.
(string) --
MatchScope (string) -- [REQUIRED]
The parts of the JSON to match against using the MatchPattern . If you specify All , AWS WAF matches against keys and values.
InvalidFallbackBehavior (string) --
What AWS WAF should do if it fails to completely parse the JSON body. The options are the following:
EVALUATE_AS_STRING - Inspect the body as plain text. AWS WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
If you don't provide this setting, AWS WAF parses and evaluates the content only up to the first parsing failure that it encounters.
AWS WAF does its best to parse the entire JSON body, but might be forced to stop for reasons such as invalid characters, duplicate keys, truncation, and any content whose root node isn't an object or an array.
AWS WAF parses the JSON in the following examples as two valid key, value pairs:
Missing comma: {"key1":"value1""key2":"value2"}
Missing colon: {"key1":"value1","key2""value2"}
Extra colons: {"key1"::"value1","key2""value2"}
TextTransformations (list) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch , starting from the lowest priority setting, before inspecting the content for a match.
(dict) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
Priority (integer) -- [REQUIRED]
Sets the relative processing order for multiple transformations that are defined for a rule statement. AWS WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don't need to be consecutive, but they must all be different.
Type (string) -- [REQUIRED]
You can specify the following transformation types:
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: " ' ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:
Replaces (ampersand)quot; with "
Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
Replaces (ampersand)lt; with a "less than" symbol
Replaces (ampersand)gt; with >
Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE if you don't want any text transformations.
PositionalConstraint (string) -- [REQUIRED]
The area within the portion of a web request that you want AWS WAF to search for SearchString . Valid values include the following:
CONTAINS
The specified part of the web request must include the value of SearchString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of SearchString , and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, SearchString must be a word, which means that both of the following are true:
SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (_). Examples include the value of a header and ;BadBot .
SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of SearchString .
STARTS_WITH
The value of SearchString must appear at the beginning of the specified part of the web request.
ENDS_WITH
The value of SearchString must appear at the end of the specified part of the web request.
SqliMatchStatement (dict) --
Attackers sometimes insert malicious SQL code into web requests in an effort to extract data from your database. To allow or block web requests that appear to contain malicious SQL code, create one or more SQL injection match conditions. An SQL injection match condition identifies the part of web requests, such as the URI or the query string, that you want AWS WAF to inspect. Later in the process, when you create a web ACL, you specify whether to allow or block requests that appear to contain malicious SQL code.

XssMatchStatement (dict) --
A rule statement that defines a cross-site scripting (XSS) match search for AWS WAF to apply to web requests. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a vehicle to inject malicious client-site scripts into other legitimate web browsers. The XSS match statement provides the location in requests that you want AWS WAF to search and text transformations to use on the search area before AWS WAF searches for character sequences that are likely to be malicious strings.
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch .
SingleHeader (dict) --
Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer . This setting isn't case sensitive.
Example JSON: "SingleHeader": { "Name": "haystack" }

RateBasedStatement (dict) --
A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.
When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.
You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:
An IP match statement with an IP set that specified the address 192.0.2.44.
A string match statement that searches in the User-Agent header for the string BadBot.
In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.
You cannot nest a RateBasedStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
Limit (integer) -- [REQUIRED]
The limit on requests per 5-minute period for a single originating IP address. If the statement includes a ScopeDownStatement , this limit is applied only to the requests that match the statement.
AggregateKeyType (string) -- [REQUIRED]
Setting that indicates how to aggregate the request counts. The options are the following:
IP - Aggregate the request counts on the IP address from the web request origin.
FORWARDED_IP - Aggregate the request counts on the first IP address in an HTTP header. If you use this, configure the ForwardedIPConfig , to specify the header to use.
ScopeDownStatement (dict) --
An optional nested statement that narrows the scope of the rate-based statement to matching web requests. This can be any nestable statement, and you can nest statements at any level below this scope-down statement.
ForwardedIPConfig (dict) --
The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that's reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
This is required if AggregateKeyType is set to FORWARDED_IP .
HeaderName (string) -- [REQUIRED]
The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For .
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
FallbackBehavior (string) -- [REQUIRED]
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Note
If the specified header isn't present in the request, AWS WAF doesn't apply the rule to the web request at all.
You can specify the following fallback behaviors:
MATCH - Treat the web request as matching the rule statement. AWS WAF applies the rule action to the request.
NO_MATCH - Treat the web request as not matching the rule statement.
AndStatement (dict) --
A logical rule statement used to combine other rule statements with AND logic. You provide more than one Statement within the AndStatement .
Statements (list) -- [REQUIRED]
The statements to combine with AND logic. You can use any statements that can be nested.
(dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.

A logical rule statement used to negate the results of another rule statement. You provide one Statement within the NotStatement .
Statement (dict) --
The statement to negate. You can use any statement that can be nested.
ManagedRuleGroupStatement (dict) --
A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups .
You can't nest a ManagedRuleGroupStatement , for example for use inside a NotStatement or OrStatement . It can only be referenced as a top-level statement within a rule.
VendorName (string) -- [REQUIRED]
The name of the managed rule group vendor. You use this, along with the rule group name, to identify the rule group.
Name (string) -- [REQUIRED]
The name of the managed rule group. You use this, along with the vendor name, to identify the rule group.
ExcludedRules (list) --
The rules whose actions are set to COUNT by the web ACL, regardless of the action that is set on the rule. This effectively excludes the rule from acting on web requests.
(dict) --
Specifies a single rule to exclude from the rule group. Excluding a rule overrides its action setting for the rule group in the web ACL, setting it to COUNT . This effectively excludes the rule from acting on web requests.
Name (string) -- [REQUIRED]
The name of the rule to exclude.
ScopeDownStatement (dict) --
The processing guidance for a Rule , used by AWS WAF to determine whether a web request matches the rule.
LabelMatchStatement (dict) --
A rule statement that defines a string match search against labels that have been added to the web request by rules that have already run in the web ACL.
The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, AWS WAF performs the search for labels that were added in the same context as the label match statement.
Scope (string) -- [REQUIRED]
Specify whether you want to match using the label name or just the namespace.
Key (string) -- [REQUIRED]
The string to match against. The setting you provide for this depends on the match statement's Scope settings:
If the Scope indicates LABEL , then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
If the Scope indicates NAMESPACE , then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name .
Action (dict) --
The action that AWS WAF should take on a web request when it matches the rule statement. Settings at the web ACL level can override the rule action setting.
This is used only for rules whose statements do not reference a rule group. Rule statements that reference a rule group include RuleGroupReferenceStatement and ManagedRuleGroupStatement .
You must specify either this Action setting or the rule OverrideAction setting, but not both:
If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
If the rule statement references a rule group, use the override action setting and not this action setting.
Block (dict) --
Instructs AWS WAF to block the web request.
CustomResponse (dict) --
Defines a custom response for the web request.

For a list of status codes that you can use in your custom reqponses, see Supported status codes for custom response in the AWS WAF Developer Guide .
CustomResponseBodyKey (string) --
References the response body that you want AWS WAF to return to the web request client. You can define a custom response for a rule action or a default web ACL action that is set to block. To do this, you first define the response body key and value in the CustomResponseBodies setting for the WebACL or RuleGroup where you want to use it. Then, in the rule action or web ACL default action BlockAction setting, you reference the response body using this key.

Rules that run after this rule in the web ACL can match against these labels using a LabelMatchStatement .
For each label, provide a case-sensitive string containing optional namespaces and a label name, according to the following guidelines:
Separate each component of the label with a colon.
Each namespace or name can have up to 128 characters.
You can specify up to 5 namespaces in a label.
Don't use the following reserved words in your label specification: aws , waf , managed , rulegroup , webacl , regexpatternset , or ipset .
For example, myLabelName or nameSpace1:nameSpace2:myLabelName .

string
[REQUIRED]
A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.
dict
