Palo Alto Firewall Auditv1.0.0

After migrating from port-based rules to App-ID, systematically verify that all new rules correctly enforce application identification and no overly permissive 'application any' rules remain. Use the rule-by-rule analysis to ensure each allow rule has specific App-IDs and proper Security Profile Groups.

Conduct a compliance-mandated review of all firewall rules to ensure they have documented business justification, no disabled or shadowed rules exist, and all allow rules include threat prevention profiles. Generate a findings report for auditors.

After a security incident, audit the security policy to identify how the malicious traffic was permitted. Use 'test security-policy-match' to trace the exact rule that allowed the traffic and assess if additional restrictions or profile updates are needed.

After network redesign or VLAN changes, verify that inter-zone policies enforce proper segmentation. Use the zone architecture inventory to confirm zone protection profiles are assigned and that rules between trust zones (e.g., DMZ to internal) are appropriately restrictive.

Before pushing policy changes from Panorama to managed firewalls, audit the device group hierarchy and pre/post-rule evaluation order to ensure no inconsistencies or shadowed rules exist across multiple firewalls. Validate that all managed firewalls have consistent Security Profile Group bindings.

Package the firewall audit as a recurring managed service for clients. Perform quarterly audits as part of a managed firewall service, providing compliance reports and actionable recommendations. Revenue generated via monthly subscription or per-audit fee.

Offer one-time or annual firewall audit consulting for organizations needing to meet regulatory standards (PCI DSS, HIPAA, SOC 2). Deliver detailed findings and remediation plans. Revenue from hourly consulting or fixed-price projects.

Provide a baseline audit before major PAN-OS version upgrades to identify rule changes needed for compatibility and to ensure current policy is clean. This minimizes upgrade risk and is billed as a standalone project.
