This is AWS WAF Classic documentation. For more information, see
AWS WAF Classic
in the developer guide.
For the latest version of AWS WAF, use the AWS WAFV2 API and see the
AWS WAF Developer Guide.
With the latest version, AWS WAF has a single set of endpoints for
regional and global use.
Inserts or deletes XssMatchTuple objects (filters) in an XssMatchSet.
For each XssMatchTuple
object, you specify the following values:
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 create_xss_match_set
request.
Use get_change_token
to get the change
token that you provide in the ChangeToken
parameter of an
update_ip_set
request.
Submit an update_xss_match_set
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.
