FREE TOOLS / FIREWALL RULE REVIEW CHECKLIST

Firewall Rule Review Checklist

Evaluate your firewall policy hygiene and rule configurations against industry best practices. No config files or policy files are ever uploaded.

1. Are there any "any-any" (unrestricted source and destination) rules?
2. Do temporary rules have a defined expiration or review date?
3. Are rule descriptions meaningful and kept up to date?
4. Is the rule owner or requesting business unit clearly identified?
5. Is administrative access restricted using dedicated rules?
6. Is source IP restriction enforced for internet-facing services?
7. Is logging enabled for all critical and high-priority rules?
8. Are rules with no hit count for a long period reviewed and pruned?
9. Are legacy user or decommissioned project rules cleaned up?
10. Are rule modifications processed through an approved change management workflow?
11. Are third-party and VPN access rules tracked and reviewed separately?
12. Is the last periodic review date of the firewall policy documented?

What is Firewall Policy Hygiene?

As firewall rule bases grow over time, complexity increases and creates security blind spots. Proper policy hygiene:

  • Restricts overly permissive access rules.
  • Prunes stale, unused rule configurations.
  • Secures critical management gateways.
  • Limits lateral movement speed of threats.
