2017/06/21 - AWS WAF Regional - 6 new 3 updated api methods
Changes You can now create, edit, update, and delete a new type of WAF rule with a rate tracking component.
Inserts or deletes Predicate objects in a rule and updates the RateLimit in the rule.
Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet , that specifies the web requests that you want to block or count. The RateLimit specifies the number of requests every five minutes that triggers the rule.
If you add more than one predicate to a RateBasedRule , a request must match all the predicates and exceed the RateLimit to be counted or blocked. For example, suppose you add the following to a RateBasedRule :
An IPSet that matches the IP address 192.0.2.44/32
A ByteMatchSet that matches BadBot in the User-Agent header
Further, you specify a RateLimit of 15,000.
You then add the RateBasedRule to a WebACL and specify that you want to block requests that satisfy the rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot . Further, requests that match these two conditions much be received at a rate of more than 15,000 every five minutes. If the rate drops below this limit, AWS WAF no longer blocks the requests.
As a second example, suppose you want to limit requests to a particular page on your site. To do this, you could add the following to a RateBasedRule :
A ByteMatchSet with FieldToMatch of URI
A PositionalConstraint of STARTS_WITH
A TargetString of login
Further, you specify a RateLimit of 15,000.
By adding this RateBasedRule to a WebACL , you could limit requests to your login page without affecting the rest of your site.

Specify INSERT to add a Predicate to a Rule . Use DELETE to remove a Predicate from a Rule .
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 .

ChangeToken (string) --
The ChangeToken that you used to submit the UpdateRateBasedRule request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus .
Creates a RateBasedRule . The RateBasedRule contains a RateLimit , which specifies the maximum number of requests that AWS WAF allows from a specified IP address in a five-minute period. The RateBasedRule also contains the IPSet objects, ByteMatchSet objects, and other predicates that identify the requests that you want to count or block if these requests exceed the RateLimit .
If you add more than one predicate to a RateBasedRule , a request not only must exceed the RateLimit , but it also must match all the specifications to be counted or blocked. For example, suppose you add the following to a RateBasedRule :
An IPSet that matches the IP address 192.0.2.44/32
A ByteMatchSet that matches BadBot in the User-Agent header
Further, you specify a RateLimit of 15,000.
You then add the RateBasedRule to a WebACL and specify that you want to block requests that meet the conditions in the rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot . Further, requests that match these two conditions must be received at a rate of more than 15,000 requests every five minutes. If both conditions are met and the rate is exceeded, AWS WAF blocks the requests. If the rate drops below 15,000 for a five-minute period, AWS WAF no longer blocks the requests.
As a second example, suppose you want to limit requests to a particular page on your site. To do this, you could add the following to a RateBasedRule :
A ByteMatchSet with FieldToMatch of URI
A PositionalConstraint of STARTS_WITH
A TargetString of login
Further, you specify a RateLimit of 15,000.
By adding this RateBasedRule to a WebACL , you could limit requests to your login page without affecting the rest of your site.
To create and configure a RateBasedRule , perform the following steps:
Create and update the predicates that you want to include in the rule. For more information, see CreateByteMatchSet , CreateIPSet , and CreateSqlInjectionMatchSet .
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateRule request.
Submit a CreateRateBasedRule request.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.
Submit an UpdateRateBasedRule request to specify the predicates that you want to include in the rule.
Create and update a WebACL that contains the RateBasedRule . For more information, see CreateWebACL .

Specifies how you want AWS WAF to respond to requests that match the settings in a Rule . Valid settings include the following:
ALLOW : AWS WAF allows requests
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 .
Type (string) --
The rule type, either REGULAR , as defined by Rule , or RATE_BASED , as defined by RateBasedRule . The default is REGULAR. Although this field is optional, be aware that if you try to add a RATE_BASED rule to a web ACL without setting the type, the UpdateWebACL request will fail because the request tries to add a REGULAR rule with the specified ID, which does not exist.
{'Updates': {'ActivatedRule': {'Type': 'REGULAR | RATE_BASED'}}}
Inserts or deletes ActivatedRule objects in a WebACL . Each Rule identifies web requests that you want to allow, block, or count. When you update a WebACL , you specify the following values:
A default action for the WebACL , either ALLOW or BLOCK . AWS WAF performs the default action if a request doesn't match the criteria in any of the Rules in a WebACL .
The Rules that you want to add and/or delete. If you want to replace one Rule with another, you delete the existing Rule and add the new one.
For each Rule , whether you want AWS WAF to allow requests, block requests, or count requests that match the conditions in the Rule .
The order in which you want AWS WAF to evaluate the Rules in a WebACL . If you add more than one Rule to a WebACL , AWS WAF evaluates each request against the Rules in order based on the value of Priority . (The Rule that has the lowest value for Priority is evaluated first.) When a web request matches all of the predicates (such as ByteMatchSets and IPSets ) in a Rule , AWS WAF immediately takes the corresponding action, allow or block, and doesn't evaluate the request against the remaining Rules in the WebACL , if any.
To create and configure a WebACL , perform the following steps:
Create and update the predicates that you want to include in Rules . For more information, see CreateByteMatchSet , UpdateByteMatchSet , CreateIPSet , UpdateIPSet , CreateSqlInjectionMatchSet , and UpdateSqlInjectionMatchSet .
Create and update the Rules that you want to include in the WebACL . For more information, see CreateRule and UpdateRule .
Create a WebACL . See CreateWebACL .
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.
Submit an UpdateWebACL request to specify the Rules that you want to include in the WebACL , to specify the default action, and to associate the WebACL with a CloudFront distribution.
Be aware that if you try to add a RATE_BASED rule to a web ACL without setting the rule type when first creating the rule, the UpdateWebACL request will fail because the request tries to add a REGULAR rule (the default rule type) with the specified ID, which does not exist.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide .

string
[REQUIRED]
The WebACLId of the WebACL that you want to update. WebACLId is returned by CreateWebACL and by ListWebACLs .
string
[REQUIRED]
The value returned by the most recent call to GetChangeToken .
list
An array of updates to make to the WebACL .
An array of WebACLUpdate objects that you want to insert into or delete from a WebACL . For more information, see the applicable data types:
WebACLUpdate : Contains Action and ActivatedRule
ActivatedRule : Contains Action , Priority , RuleId , and Type
WafAction : Contains Type
(dict) --
Specifies whether to insert a Rule into or delete a Rule from a WebACL .
Action (string) -- [REQUIRED]
Specifies whether to insert a Rule into or delete a Rule from a WebACL .
ActivatedRule (dict) -- [REQUIRED]
The ActivatedRule object in an UpdateWebACL request specifies a Rule that you want to insert or delete, the priority of the Rule in the WebACL , and the action that you want AWS WAF to take when a web request matches the Rule (ALLOW , BLOCK , or COUNT ).
Priority (integer) -- [REQUIRED]
Specifies the order in which the Rules in a WebACL are evaluated. Rules with a lower value for Priority are evaluated before Rules with a higher value. The value must be a unique integer. If you add multiple Rules to a WebACL , the values don't need to be consecutive.
RuleId (string) -- [REQUIRED]
The RuleId for a Rule . You use RuleId to get more information about a Rule (see GetRule ), update a Rule (see UpdateRule ), insert a Rule into a WebACL or delete a one from a WebACL (see UpdateWebACL ), or delete a Rule from AWS WAF (see DeleteRule ).
RuleId is returned by CreateRule and by ListRules .
Action (dict) -- [REQUIRED]
Specifies the action that CloudFront or AWS WAF takes when a web request matches the conditions in the Rule . Valid values for Action include the following:
ALLOW : CloudFront responds with the requested object.
BLOCK : CloudFront responds with an HTTP 403 (Forbidden) status code.
COUNT : AWS WAF increments a counter of requests that match the conditions in the rule and then continues to inspect the web request based on the remaining rules in the web ACL.
Type (string) -- [REQUIRED]
Specifies how you want AWS WAF to respond to requests that match the settings in a Rule . Valid settings include the following:
ALLOW : AWS WAF allows requests
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 .
Type (string) --
The rule type, either REGULAR , as defined by Rule , or RATE_BASED , as defined by RateBasedRule . The default is REGULAR. Although this field is optional, be aware that if you try to add a RATE_BASED rule to a web ACL without setting the type, the UpdateWebACL request will fail because the request tries to add a REGULAR rule with the specified ID, which does not exist.
dict
A default action for the web ACL, either ALLOW or BLOCK. AWS WAF performs the default action if a request doesn't match the criteria in any of the rules in a web ACL.
Type (string) -- [REQUIRED]
