A WAF Policy is the set of WAF configurations for a distribution or a group of distributions. Most of the time, the same WAF rules are used for several distributions. Therefore, we combined them under policies. You can create a policy and apply it to as many distributions as you want. You can also generate and save several WAF policies for different security levels and conditions.
A policy contains Managed Rules settings and Custom Rules. Each policy has a unique name, which is the identifier of it.
