Our Firewall Rule Set Review Methodology
A structured, rule-by-rule approach to reduce risk and complexity in your rule bases.
Scope & Collection
Agree firewalls in scope and collect rule bases and configurations.
Business Context
Understand zones, critical services and approved traffic flows.
Permissive Rule Analysis
Identify any-any, broad port ranges and overly open sources or destinations.
Redundancy & Shadowing
Find duplicate, shadowed and conflicting rules.
Usage & Aging Review
Identify unused, expired or temporary rules using logs where available.
Change Control Check
Compare rules against approvals, owners and business justification.
Reporting
Deliver findings, risk ratings and rule-level clean-up recommendations.
Revalidation & Closure
Re-review updated rule bases and document residual risk.
Deliverables You Can Expect
Every engagement reviews rules individually, not just device-level settings.
Supporting Services
Extend firewall review into configuration audits, segmentation testing and architecture review.

Frequently Asked Questions
It analyzes each rule for permissive access, redundancy, shadowing, usage and business justification, across the firewalls and rule bases you agree.
A configuration review checks device settings such as management access and logging. A rule set review focuses on the rules that allow or block traffic.
PCI DSS requires network security control configurations to be reviewed at least every six months. Many organizations align other firewalls to a similar cycle.
No. QRC recommends specific changes; your team approves and applies them, and QRC can re-review the updated rule base.
