The RegexPatternSet specifies the regular expression (regex) pattern that you want AWS WAF to search for, such as B[a@]dB[o0]t. You can then configure AWS WAF to reject those requests.
Note that you can only create regex pattern sets using a AWS CloudFormation template. To add the regex pattern sets created through AWS CloudFormation to a RegexMatchSet, use the AWS WAF console, API, or command line interface (CLI). For more information, see UpdateRegexMatchSet.
