Section 02 · Analysis
SecOps Signal analysisSOC analysts and security engineers can use WAF exceptions in Azure Application Gateway and Azure Front Door to tune false positives precisely without entirely disabling rules or broad exclusions.
Reduces operational alert fatigue by suppressing known safe requests while maintaining strict rule enforcement for the remainder of the web traffic.
Section 03 · Recommended actions
- Navigate to WAF policies in the Azure portal, select Managed rules, and configure exceptions for expected traffic patterns that previously triggered false positives.
- Review current WAF policies in the Azure portal under Managed rules to identify frequently occurring false positives.
- Evaluate whether fine-grained exceptions based on request URI, remote IP address, or header name and value are more appropriate than broad exclusions.
