Firewall Security Audit Procedure
Firewall Rules Review
Remove overly permissive, obsolete, or risky rules.
We analyze every rule for necessity, scope, and alignment with security best practices.
Access Control Policies
Ensure least-privilege principles are applied.
We verify that users and systems only have access to what they absolutely need — nothing more.
Change Management
Validate documentation of all firewall rule changes.
We assess whether proper approval, tracking, and rollback procedures are in place for every change.
Logging & Monitoring
Verify logging is active and sent to a SIEM or SOC.
We also check that alerts are actionable and monitored consistently to detect suspicious activity in real time.
Firmware & Patch Review
Ensure the firewall OS is up-to-date.
We look for known vulnerabilities and confirm your devices are patched against the latest threats.
Redundancy & Failover
Assess HA configuration and reliability.
We simulate failover scenarios to ensure your firewall infrastructure won’t become a single point of failure.
