How to configure a WAF Custom Allowed Rule

Configuring a WAF Custom Allowed Rule allows you to instantiate specific rules for the needs of your application. These rules permit specific, legitimate traffic while maintaining robust protection against malicious attacks.

This guide explains how to configure a WAF Custom Allowed Rule via Azion Web Platform.

To instantiate Custom Allowed Rules in a WAF Rule Set, you must have:

• A firewall with the Web Application Firewall module activated.
