Generating Amazon Web Services WAF Rules From Invicti

This document is for:

Invicti Standard

Amazon Web Services Web Application Firewall (AWS WAF) enables you to monitor the HTTP and HTTPS requests that are forwarded to an Amazon CloudFront, Application Load Balancer or API Gateway. With AWS WAF, you can create rules for traffic to allow or block requests. This function is only available in Invicti Standard.

If you can't immediately fix all vulnerabilities that Invicti has detected, you can cover them up and defer fixing them until another time. This is achieved by exporting Invicti’s findings as rules for the AWS WAF.

Since AWS WAF has limits for Regex patterns, be careful not to exceed them, otherwise Invicti cannot create the rule.

For more information about AWS WAF, see AWS WAF, AWS Firewall Manager, and AWS Shield Advanced and AWS WAF Limits.

See the Web Application Firewalls before reading this document. It describes WAF rule creation process and how to configure Auto WAF Rule.

This topic explains how to configure Invicti Standard to send a detected vulnerability to AWS WAF.
