XssMatchStatement - AWS WAFV2

XssMatchStatement

Note

This is the latest version of AWS WAF, named AWS WAFV2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide.

A rule statement that defines a cross-site scripting (XSS) match search for AWS WAF to apply to web requests. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a vehicle to inject malicious client-site scripts into other legitimate web browsers. The XSS match statement provides the location in requests that you want AWS WAF to search and text transformations to use on the search area before AWS WAF searches for character sequences that are likely to be malicious strings.

Contents

FieldToMatch

The part of a web request that you want AWS WAF to inspect. For more information, see FieldToMatch.

Type: FieldToMatch object

Required: Yes

TextTransformations

Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. If you specify one or more transformations in a rule statement, AWS WAF performs all transformations on the content of the request component identified by FieldToMatch, starting from the lowest priority setting, before inspecting the content for a match.

Type: Array of TextTransformation objects

Array Members: Minimum number of 1 item.
