Firewall rule review is the examination of firewall policy to verify that network access rules are still necessary, correct, and appropriately restricted. It matters because firewall policies tend to grow messy and over-permissive over time unless someone actively cleans them up.
What is Firewall Rule Review?
Review helps identify stale rules, shadowed rules, overly broad access, temporary exceptions that never expired, and gaps between policy intent and implementation. It supports stronger segmentation and lower exposure.
What Firewall Rule Review Commonly Supports
Common uses include change governance, network hardening, audit readiness, segmentation improvement, and risk reduction from outdated access paths.
Firewall Rule Review vs. Untended Firewall Policy
Rule review keeps policy aligned to current need and risk. Untended policy accumulates drift, clutter, and excessive permissions over time.
Frequently Asked Questions
Why review firewall rules regularly?
Because exceptions and temporary access often linger long after the original need has disappeared.
Is this only a compliance exercise?
No. It is also a practical way to reduce attack surface and simplify incident response.
