Acl Rule Analysisv0.1.1

After migrating from one firewall platform to another (e.g., Cisco ASA to Palo Alto), this skill identifies shadowed rules introduced during migration and overly permissive rules that were copied over. It ensures the new rulebase is lean and secure, removing technical debt.

Financial organizations subject to PCI-DSS or SOX must maintain least privilege. This skill scans firewall policies quarterly to detect unused rules with zero hits over 90 days, flags overly permissive rules like 'permit any any', and suggests removals to reduce attack surface.

When two companies merge, their overlapping firewall policies often contain redundant rules. This skill analyzes both rulebases, identifies common patterns, and recommends consolidated rules that eliminate shadows and redundancies while preserving security intent.

During a security incident, this skill helps determine if a specific malicious traffic flow matched an existing firewall rule. By analyzing rule hit counts and match criteria, it confirms whether the rulebase was breached or if the traffic was properly blocked, aiding forensic conclusions.

When preparing for an audit (e.g., ISO 27001), this skill identifies overly permissive rules such as 'permit ip any any' and suggests narrowing them based on actual traffic logs. It provides a clear audit trail of rule justifications and minimizations.
