AWS WAF Regional

2018/11/06 - AWS WAF Regional - 3 updated api methods

Changes  You can now use AWS WAF to configure protections for your Amazon API Gateway APIs. This will enable you to block (or count) undesired traffic to your APIs based on the different AWS WAF rules and conditions you create. For more information about AWS WAF, see the AWS WAF Developer Guide.

CreateWebACL (updated) Link ¶
Changes (response)
{'WebACL': {'WebACLArn': 'string'}}

Creates a WebACL , which contains the Rules that identify the CloudFront web requests that you want to allow, block, or count. AWS WAF evaluates Rules in order based on the value of Priority for each Rule .

You also specify a default action, either ALLOW or BLOCK . If a web request doesn't match any of the Rules in a WebACL , AWS WAF responds to the request with the default action.

To create and configure a WebACL , perform the following steps:

  • Create and update the ByteMatchSet objects and other 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 .

  • Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateWebACL request.

  • Submit a CreateWebACL request.

  • 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.

For more information about how to use the AWS WAF API, see the AWS WAF Developer Guide .

Response Structure

  • (dict) --

    • WebACL (dict) --

      The WebACL returned in the CreateWebACL response.

      • WebACLId (string) --

        A unique identifier for a WebACL . You use WebACLId to get information about a WebACL (see GetWebACL ), update a WebACL (see UpdateWebACL ), and delete a WebACL from AWS WAF (see DeleteWebACL ).

        WebACLId is returned by CreateWebACL and by ListWebACLs .

      • Name (string) --

        A friendly name or description of the WebACL . You can't change the name of a WebACL after you create it.

      • MetricName (string) --

        A friendly name or description for the metrics for this WebACL . The name can contain only alphanumeric characters (A-Z, a-z, 0-9); the name can't contain whitespace. You can't change MetricName after you create the WebACL .

      • DefaultAction (dict) --

        The action to perform if none of the Rules contained in the WebACL match. The action is specified by the WafAction object.

        • Type (string) --

          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 .

      • Rules (list) --

        An array that contains the action for each Rule in a WebACL , the priority of the Rule , and the ID of the Rule .

        • (dict) --

          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 ).

          To specify whether to insert or delete a Rule , use the Action parameter in the WebACLUpdate data type.

          • Priority (integer) --

            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) --

            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) --

            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.

            ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL . In this case you do not use ActivatedRule|Action . For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction .

            • Type (string) --

              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 .

          • OverrideAction (dict) --

            Use the OverrideAction to test your RuleGroup .

            Any rule in a RuleGroup can potentially block a request. If you set the OverrideAction to None , the RuleGroup will block a request if any individual rule in the RuleGroup matches the request and is configured to block that request. However if you first want to test the RuleGroup , set the OverrideAction to Count . The RuleGroup will then override any block action specified by individual rules contained within the group. Instead of blocking matching requests, those requests will be counted. You can view a record of counted requests using GetSampledRequests .

            ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL . In this case you do not use ActivatedRule|Action . For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction .

            • Type (string) --

              COUNT overrides the action specified by the individual rule within a RuleGroup . If set to NONE , the rule's action will take place.

          • Type (string) --

            The rule type, either REGULAR , as defined by Rule , RATE_BASED , as defined by RateBasedRule , or GROUP , as defined by RuleGroup . 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.

      • WebACLArn (string) --

        Tha Amazon Resource Name (ARN) of the web ACL.

    • ChangeToken (string) --

      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 .
