Inserts or deletes ByteMatchTuple objects (filters) in a ByteMatchSet . For each ByteMatchTuple object, you specify the following values:
Whether to insert or delete the object from the array. If you want to change a ByteMatchSetUpdate object, you delete the existing object and add a new one.
The part of a web request that you want AWS WAF to inspect, such as a query string or the value of the User-Agent header.
The bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to look for. For more information, including how you specify the values for the AWS WAF API and the AWS CLI or SDKs, see TargetString in the ByteMatchTuple data type.
Where to look, such as at the beginning or the end of a query string.
Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.
For example, you can add a ByteMatchSetUpdate object that matches web requests in which User-Agent headers contain the string BadBot . You can then configure AWS WAF to block those requests.
To create and configure a ByteMatchSet , perform the following steps:
Create a ByteMatchSet. For more information, see CreateByteMatchSet .
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateByteMatchSet request.
Submit an UpdateByteMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide .

ByteMatchSetUpdate : Contains Action and ByteMatchTuple
ByteMatchTuple : Contains FieldToMatch , PositionalConstraint , TargetString , and TextTransformation
FieldToMatch : Contains Data and Type
(dict) --
In an UpdateByteMatchSet request, ByteMatchSetUpdate specifies whether to insert or delete a ByteMatchTuple and includes the settings for the ByteMatchTuple .
Action (string) -- [REQUIRED]
Specifies whether to insert or delete a ByteMatchTuple .
ByteMatchTuple (dict) -- [REQUIRED]
Information about the part of a web request that you want AWS WAF to inspect and the value that you want AWS WAF to search for. If you specify DELETE for the value of Action , the ByteMatchTuple values must exactly match the values in the ByteMatchTuple that you want to delete from the ByteMatchSet .
FieldToMatch (dict) -- [REQUIRED]
The part of a web request that you want AWS WAF to search, such as a specified header or a query string. For more information, see FieldToMatch .
Type (string) -- [REQUIRED]
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER : A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data .
METHOD : The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : A query string, which is the part of a URL that appears after a ? character, if any.
URI : The part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
BODY : 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. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
Data (string) --
When the value of Type is HEADER , enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer . If the value of Type is any other value, omit Data .
The name of the header is not case sensitive.
TargetString (bytes) -- [REQUIRED]
The value that you want AWS WAF to search for. AWS WAF searches for the specified string in the part of web requests that you specified in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the values that you specified for FieldToMatch :
HEADER : The value that you want AWS WAF to search for in the request header that you specified in FieldToMatch , for example, the value of the User-Agent or Referer header.
METHOD : The HTTP method, which indicates the type of operation specified in the request. CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : The value that you want AWS WAF to search for in the query string, which is the part of a URL that appears after a ? character.
URI : The value that you want AWS WAF to search for in the part of a URL that identifies a resource, for example, /images/daily-ad.jpg .
BODY : 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. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
If TargetString 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 TargetString .
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.
TextTransformation (string) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on TargetString before inspecting a request for a match.
CMD_LINE
When you're concerned that attackers are injecting an operating system commandline 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 to perform any text transformations.
PositionalConstraint (string) -- [REQUIRED]
Within the portion of a web request that you want to search (for example, in the query string, if any), specify where you want AWS WAF to search. Valid values include the following:
CONTAINS
The specified part of the web request must include the value of TargetString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of TargetString , and TargetString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, TargetString must be a word, which means one of the following:
TargetString exactly matches the value of the specified part of the web request, such as the value of a header.
TargetString is at the beginning of the specified part of the web request and is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; .
TargetString is at the end of the specified part of the web request and is preceded by a character other than an alphanumeric character or underscore (_), for example, ;BadBot .
TargetString is in the middle of the specified part of the web request and is preceded and followed by characters other than alphanumeric characters or underscore (_), for example, -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of TargetString .
STARTS_WITH
The value of TargetString must appear at the beginning of the specified part of the web request.
ENDS_WITH
The value of TargetString must appear at the end of the specified part of the web request.

You use ByteMatchSetId to get information about a ByteMatchSet (see GetByteMatchSet ), update a ByteMatchSet (see UpdateByteMatchSet ), insert a ByteMatchSet into a Rule or delete one from a Rule (see UpdateRule ), and delete a ByteMatchSet from AWS WAF (see DeleteByteMatchSet ).
ByteMatchSetId is returned by CreateByteMatchSet and by ListByteMatchSets .
Name (string) --
A friendly name or description of the ByteMatchSet . You can't change Name after you create a ByteMatchSet .
ByteMatchTuples (list) --
Specifies the bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to search for in web requests, the location in requests that you want AWS WAF to search, and other settings.
(dict) --
The bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to search for in web requests, the location in requests that you want AWS WAF to search, and other settings.
FieldToMatch (dict) --
The part of a web request that you want AWS WAF to search, such as a specified header or a query string. For more information, see FieldToMatch .
Type (string) --
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER : A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data .
METHOD : The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : A query string, which is the part of a URL that appears after a ? character, if any.
URI : The part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
BODY : 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. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
Data (string) --
When the value of Type is HEADER , enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer . If the value of Type is any other value, omit Data .
The name of the header is not case sensitive.
TargetString (bytes) --
The value that you want AWS WAF to search for. AWS WAF searches for the specified string in the part of web requests that you specified in FieldToMatch . The maximum length of the value is 50 bytes.
Valid values depend on the values that you specified for FieldToMatch :
HEADER : The value that you want AWS WAF to search for in the request header that you specified in FieldToMatch , for example, the value of the User-Agent or Referer header.
METHOD : The HTTP method, which indicates the type of operation specified in the request. CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : The value that you want AWS WAF to search for in the query string, which is the part of a URL that appears after a ? character.
URI : The value that you want AWS WAF to search for in the part of a URL that identifies a resource, for example, /images/daily-ad.jpg .
BODY : 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. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
If TargetString 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 TargetString .
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.
TextTransformation (string) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on TargetString before inspecting a request for a match.
CMD_LINE
When you're concerned that attackers are injecting an operating system commandline 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

PositionalConstraint (string) --
Within the portion of a web request that you want to search (for example, in the query string, if any), specify where you want AWS WAF to search. Valid values include the following:
CONTAINS
The specified part of the web request must include the value of TargetString , but the location doesn't matter.
CONTAINS_WORD
The specified part of the web request must include the value of TargetString , and TargetString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or _). In addition, TargetString must be a word, which means one of the following:
TargetString exactly matches the value of the specified part of the web request, such as the value of a header.
TargetString is at the beginning of the specified part of the web request and is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; .
TargetString is at the end of the specified part of the web request and is preceded by a character other than an alphanumeric character or underscore (_), for example, ;BadBot .
TargetString is in the middle of the specified part of the web request and is preceded and followed by characters other than alphanumeric characters or underscore (_), for example, -BadBot; .
EXACTLY
The value of the specified part of the web request must exactly match the value of TargetString .
STARTS_WITH
The value of TargetString must appear at the beginning of the specified part of the web request.

Inserts or deletes XssMatchTuple objects (filters) in an XssMatchSet . For each XssMatchTuple object, you specify the following values:
Action : Whether to insert the object into or delete the object from the array. To change a XssMatchTuple , you delete the existing object and add a new one.
FieldToMatch : The part of web requests that you want AWS WAF to inspect and, if you want AWS WAF to inspect a header, the name of the header.
TextTransformation : Which text transformation, if any, to perform on the web request before inspecting the request for cross-site scripting attacks.
You use XssMatchSet objects to specify which CloudFront requests you want to allow, block, or count. For example, if you're receiving requests that contain cross-site scripting attacks in the request body and you want to block the requests, you can create an XssMatchSet with the applicable settings, and then configure AWS WAF to block the requests.
To create and configure an XssMatchSet , perform the following steps:
Submit a CreateXssMatchSet request.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.
Submit an UpdateXssMatchSet request to specify the parts of web requests that you want AWS WAF to inspect for cross-site scripting attacks.

FieldToMatch : The part of web requests that you want AWS WAF to inspect and, if you want AWS WAF to inspect a header, the name of the header.
TextTransformation : Which text transformation, if any, to perform on the web request before inspecting the request for snippets of malicious SQL code.
You use SqlInjectionMatchSet objects to specify which CloudFront requests you want to allow, block, or count. For example, if you're receiving requests that contain snippets of SQL code in the query string and you want to block the requests, you can create a SqlInjectionMatchSet with the applicable settings, and then configure AWS WAF to block the requests.
To create and configure a SqlInjectionMatchSet , perform the following steps:
Submit a CreateSqlInjectionMatchSet request.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.
Submit an UpdateSqlInjectionMatchSet request to specify the parts of web requests that you want AWS WAF to inspect for snippets of SQL code.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide .

Specifies the part of a web request that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header.
FieldToMatch (dict) -- [REQUIRED]
Specifies where in a web request to look for snippets of malicious SQL code.
Type (string) -- [REQUIRED]
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER : A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data .
METHOD : The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : A query string, which is the part of a URL that appears after a ? character, if any.
URI : The part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
BODY : 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. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
Data (string) --
When the value of Type is HEADER , enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer . If the value of Type is any other value, omit Data .
The name of the header is not case sensitive.
TextTransformation (string) -- [REQUIRED]
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting a request for a match.

The ChangeToken that you used to submit the CreateWebACL request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus .
When you want to create, update, or delete AWS WAF objects, get a change token and include the change token in the create, update, or delete request. Change tokens ensure that your application doesn't submit conflicting requests to AWS WAF.
Each create, update, or delete request must use a unique change token. If your application submits a GetChangeToken request and then submits a second GetChangeToken request before submitting a create, update, or delete request, the second GetChangeToken request returns the same value as the first GetChangeToken request.
When you use a change token in a create, update, or delete request, the status of the change token changes to PENDING , which indicates that AWS WAF is propagating the change to all AWS WAF servers. Use GetChangeTokenStatus to determine the status of your change token.

Inserts or deletes IPSetDescriptor objects in an IPSet . For each IPSetDescriptor object, you specify the following values:
Whether to insert or delete the object from the array. If you want to change an IPSetDescriptor object, you delete the existing object and add a new one.
The IP address version, IPv4 or IPv6 .
The IP address in CIDR notation, for example, 192.0.2.0/24 (for the range of IP addresses from 192.0.2.0 to 192.0.2.255 ) or 192.0.2.44/32 (for the individual IP address 192.0.2.44 ).
AWS WAF supports /8, /16, /24, and /32 IP address ranges for IPv4, and /24, /32, /48, /56, /64 and /128 for IPv6. For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing .
IPv6 addresses can be represented using any of the following formats:
1111:0000:0000:0000:0000:0000:0000:0111/128
1111:0:0:0:0:0:0:0111/128
1111::0111/128
1111::111/128
You use an IPSet to specify which web requests you want to allow or block based on the IP addresses that the requests originated from. For example, if you're receiving a lot of requests from one or a small number of IP addresses and you want to block the requests, you can create an IPSet that specifies those IP addresses, and then configure AWS WAF to block the requests.
To create and configure an IPSet , perform the following steps:
Submit a CreateIPSet request.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.
Submit an UpdateIPSet request to specify the IP addresses that you want AWS WAF to watch for.
When you update an IPSet , you specify the IP addresses that you want to add and/or the IP addresses that you want to delete. If you want to change an IP address, you delete the existing IP address and add the new one.

FieldToMatch (dict) --
Specifies where in a web request to look for the size constraint.
Type (string) --
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER : A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data .
METHOD : The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : A query string, which is the part of a URL that appears after a ? character, if any.
URI : The part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
BODY : 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. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
Data (string) --
When the value of Type is HEADER , enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer . If the value of Type is any other value, omit Data .
The name of the header is not case sensitive.
TextTransformation (string) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting a request for a match.
Note that if you choose BODY for the value of Type , you must choose NONE for TextTransformation because CloudFront forwards only the first 8192 bytes for inspection.
NONE
Specify NONE if you don't want to perform any text transformations.
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

Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
ComparisonOperator (string) --
The type of comparison you want AWS WAF to perform. AWS WAF uses this in combination with the provided Size and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch ". If that expression is true, the SizeConstraint is considered to match.
EQ : Used to test if the Size is equal to the size of the FieldToMatch
NE : Used to test if the Size is not equal to the size of the FieldToMatch
LE : Used to test if the Size is less than or equal to the size of the FieldToMatch
LT : Used to test if the Size is strictly less than the size of the FieldToMatch
GE : Used to test if the Size is greater than or equal to the size of the FieldToMatch
GT : Used to test if the Size is strictly greater than the size of the FieldToMatch
Size (integer) --
The size in bytes that you want AWS WAF to compare against the size of the specified FieldToMatch . AWS WAF uses this in combination with ComparisonOperator and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch ". If that expression is true, the SizeConstraint is considered to match.
Valid values for size are 0 - 21474836480 bytes (0 - 20 GB).
If you specify URI for the value of Type , the / in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.
Creates a SizeConstraintSet . You then use UpdateSizeConstraintSet to identify the part of a web request that you want AWS WAF to check for length, such as the length of the User-Agent header or the length of the query string. For example, you can create a SizeConstraintSet that matches any requests that have a query string that is longer than 100 bytes. You can then configure AWS WAF to reject those requests.
To create and configure a SizeConstraintSet , perform the following steps:
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateSizeConstraintSet request.
Submit a CreateSizeConstraintSet request.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateSizeConstraintSet request.
Submit an UpdateSizeConstraintSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

BLOCK : AWS WAF blocks requests
COUNT : AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL .

The ChangeToken that you used to submit the UpdateWebACL request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus .
Inserts or deletes Predicate objects in a Rule . Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet , that specifies the web requests that you want to allow, block, or count. If you add more than one predicate to a Rule , a request must match all of the specifications to be allowed, blocked, or counted. For example, suppose you add the following to a Rule :
A ByteMatchSet that matches the value BadBot in the User-Agent header
An IPSet that matches the IP address 192.0.2.44
You then add the Rule to a WebACL and specify that you want to block requests that satisfy the Rule . For a request to be blocked, the User-Agent header in the request must contain the value BadBot and the request must originate from the IP address 192.0.2.44.
To create and configure a Rule , perform the following steps:
Create and update the predicates that you want to include in the Rule .
Create the Rule . See CreateRule .
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.
Submit an UpdateRule request to add predicates to the Rule .
Create and update a WebACL that contains the Rule . See CreateWebACL .
If you want to replace one ByteMatchSet or IPSet with another, you delete the existing one and add the new one.

Predicate (dict) -- [REQUIRED]
The ID of the Predicate (such as an IPSet ) that you want to add to a Rule .
Negated (boolean) -- [REQUIRED]
Set Negated to False if you want AWS WAF to allow, block, or count requests based on the settings in the specified ByteMatchSet , IPSet , SqlInjectionMatchSet , XssMatchSet , or SizeConstraintSet . For example, if an IPSet includes the IP address 192.0.2.44 , AWS WAF will allow or block requests based on that IP address.
Set Negated to True if you want AWS WAF to allow or block a request based on the negation of the settings in the ByteMatchSet , IPSet , SqlInjectionMatchSet , XssMatchSet , or SizeConstraintSet . For example, if an IPSet includes the IP address 192.0.2.44 , AWS WAF will allow, block, or count requests based on all IP addresses except 192.0.2.44 .
Type (string) -- [REQUIRED]
The type of predicate in a Rule , such as ByteMatchSet or IPSet .
DataId (string) -- [REQUIRED]

Creates a SqlInjectionMatchSet , which you use to allow, block, or count requests that contain snippets of SQL code in a specified part of web requests. AWS WAF searches for character sequences that are likely to be malicious strings.
To create and configure a SqlInjectionMatchSet , perform the following steps:
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateSqlInjectionMatchSet request.
Submit a CreateSqlInjectionMatchSet request.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateSqlInjectionMatchSet request.
Submit an UpdateSqlInjectionMatchSet request to specify the parts of web requests in which you want to allow, block, or count malicious SQL code.

Response Structure
(dict) --
The response to a CreateSqlInjectionMatchSet request.
SqlInjectionMatchSet (dict) --
A SqlInjectionMatchSet .
SqlInjectionMatchSetId (string) --
A unique identifier for a SqlInjectionMatchSet . You use SqlInjectionMatchSetId to get information about a SqlInjectionMatchSet (see GetSqlInjectionMatchSet ), update a SqlInjectionMatchSet (see UpdateSqlInjectionMatchSet ), insert a SqlInjectionMatchSet into a Rule or delete one from a Rule (see UpdateRule ), and delete a SqlInjectionMatchSet from AWS WAF (see DeleteSqlInjectionMatchSet ).
SqlInjectionMatchSetId is returned by CreateSqlInjectionMatchSet and by ListSqlInjectionMatchSets .
Name (string) --
The name, if any, of the SqlInjectionMatchSet .
SqlInjectionMatchTuples (list) --
Specifies the parts of web requests that you want to inspect for snippets of malicious SQL code.
(dict) --
Specifies the part of a web request that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header.
FieldToMatch (dict) --
Specifies where in a web request to look for snippets of malicious SQL code.
Type (string) --
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER : A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data .
METHOD : The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE , GET , HEAD , OPTIONS , PATCH , POST , and PUT .
QUERY_STRING : A query string, which is the part of a URL that appears after a ? character, if any.
URI : The part of a web request that identifies a resource, for example, /images/daily-ad.jpg .
BODY : 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. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet .
Data (string) --
When the value of Type is HEADER , enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer . If the value of Type is any other value, omit Data .
The name of the header is not case sensitive.
TextTransformation (string) --
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting a request for a match.
CMD_LINE
When you're concerned that attackers are injecting an operating system commandline 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 to perform any text transformations.
ChangeToken (string) --
The ChangeToken that you used to submit the CreateSqlInjectionMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus .
