What is Cisco Firewall Audit?
The Cisco Firewall Audit skill provides a dual-platform framework for conducting deep-dive security assessments on Cisco ASA (classic) and Firepower Threat Defense (FTD) systems. Unlike basic port scanners, this Openclaw Skills integration analyzes platform-specific architectures, including ASA security levels and FTD Access Control Policies (ACP). It ensures that your firewall configurations align with modern security standards by evaluating Snort IPS integration, VPN encryption strengths, and Modular Policy Framework (MPF) maps.
This skill is designed for network security engineers and auditors who need to validate complex rule sets across physical and virtual appliances. By leveraging both the diagnostic CLI and management interfaces (FMC/FDM), it provides a holistic view of the security posture, identifying gaps in rule ordering, overly permissive entries, and logging deficiencies that could leave a network vulnerable.
Cisco Firewall Audit Use Cases
- Annual or quarterly compliance audits requiring per-rule justification and risk assessment.
- Post-incident forensic reviews to identify how specific traffic was permitted through the firewall.
- Pre-migration baselining when converting from legacy ASA hardware to Firepower Threat Defense.
- Validation of NAT policies following significant network re-addressing or infrastructure changes.
- Assessing VPN security to ensure remote access and site-to-site tunnels use modern, high-strength encryption.
How Cisco Firewall Audit Works
- Perform Platform Identification to determine if the device is ASA or FTD and inventory the architectural baseline, including software versions and licensed features.
- Execute Access Policy Analysis by evaluating interface-bound ACLs on ASA or Access Control Policies on FTD, looking for 'permit any' risks and unused rules.
- Conduct a NAT Policy Audit to verify the three-section evaluation order and identify rule conflicts between manual and auto-NAT.
- Review Inspection and IPS settings, checking ASA Modular Policy Framework maps or FTD Snort IPS and File/Malware policy bindings.
- Audit VPN and Remote Access configurations for cryptographic strength (IKEv2, AES-256) and secure authentication methods.
- Verify Logging and Monitoring completeness to ensure security events are correctly captured at the informational level and forwarded to SIEMs.
Cisco Firewall Audit Setup
Ensure you have SSH access to the target device. Openclaw Skills requires a minimum privilege level for read-only commands.
# For ASA: Ensure Privilege Level 5+
ssh admin@asa-hostname
show version
# For FTD: Access the diagnostic CLI
system support diagnostic-cli
show access-control-config
Cisco Firewall Audit Data Schema & Taxonomy
The audit organizes findings based on platform-specific logic and severity levels. Data is typically structured as follows:
| Component | Data Tracked |
|---|---|
| ACL/ACE | Hit counts, rule ordering, and object group expansions |
| NAT | Section 1 (Manual), Section 2 (Auto), and Section 3 (After-Auto) rules |
| VPN | IKE/IPSec SA lifetimes, DH groups, and encryption algorithms |
| IPS | Snort ruleset (e.g., Balanced Security) and deployment mode (Inline/Passive) |
| Logging | Syslog severity levels (0-7) and eStreamer connectivity status |
Cisco Firewall Audit Advanced Features
- Multi-context ASA support: Capability to switch between security contexts for independent auditing.
- Packet Tracer Simulation: Use of the packet-tracer utility to verify policy evaluation phases (NAT, ACL, Routing) for specific flows.
- FTD Diagnostic CLI integration: Accessing the ASA-derived data plane within Firepower for low-level troubleshooting.
- Threshold-based Severity Classification: Automated categorization of findings from Critical (e.g., permit any any) to Low.
