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.
