Action
: Whether to insert the object into or delete the object
from the array. To change an 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 or custom query
parameter, the name of the header or parameter.
TextTransformation
: Which text transformation, if any, to perform
on the web request before inspecting the request for cross-site
scripting attacks.
You can only specify a single type of TextTransformation.
You use XssMatchSet
objects to specify which CloudFront requests that
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.
For more information about how to use the AWS WAF API to allow or block
HTTP requests, see the AWS WAF Developer Guide.
