Amazon Managed Rules for Amazon WAF

Amazon Managed Rules for Amazon WAF is a managed service that provides protection against common application vulnerabilities or other unwanted traffic. You have the option of selecting one or more rule groups from Amazon Managed Rules for each web ACL, up to the maximum web ACL capacity unit (WCU) limit.

Mitigating false positives and testing rule group changes

Before using any managed rule group in production, test it in a non-production environment according to the guidance at Testing and tuning your Amazon WAF protections. Follow the testing and tuning guidance when you add a rule group to your web ACL, to test a new version of a rule group, and whenever a rule group isn't handling your web traffic as you need it to.

When used in accordance with the documentation, Amazon Managed Rules rule groups add another layer of security for your applications. However, Amazon Managed Rules rule groups aren't intended as a replacement for your security responsibilities, which are determined by the Amazon resources that you select.
