Parameters

>> from AWS CloudFormation Documentation

Explanation in CloudFormation Registry

Note 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. A combination of ByteMatchSet, IPSet, and/or SqlInjectionMatchSet objects that identify the web requests that you want to allow, block, or count. For example, you might create a Rule that includes the following predicates:+ An IPSet that causes AWS WAF to search for web requests that originate from the IP address 192.0.2.44 + A ByteMatchSet that causes AWS WAF to search for web requests for which the value of the User-Agent header is BadBot.

To match the settings in this Rule, a request must originate from 192.0.2.44 AND include a User-Agent header for which the value is BadBot.
