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.
