acl-rule-analysis

separate

Vendor-agnostic ACL and firewall rule analysis with shadowed rule detection, overly permissive rule identification, unused rule discovery, redundant rule flagging, and rule ordering optimization. Covers ACLs (Cisco/JunOS/EOS) and firewall policies (PAN-OS/FortiGate/CheckPoint).

When to use

• Post-migration rule cleanup after converting from one platform to another
• Periodic rulebase hygiene to remove accumulated technical debt
• Compliance preparation requiring rule-level justification and minimal privilege
• Incident investigation — determining whether a rule permitted malicious traffic
• Change validation after rulebase modifications to confirm no shadowed rules
• Capacity optimization — reducing rule count to improve lookup performance
• Merger/acquisition integration — consolidating overlapping rulebases

When not to use

• vendor-specific firewall audit skills
• platform feature evaluation (App-ID, Security Profile Groups, zone protection)
