Strengthen your Cisco network by automating configuration audits with ease. A practical guide to security compliance checking.
Introduction
Network security and infrastructure reliability depend heavily on correctly configured network devices, especially Cisco routers, switches, and firewalls. A single misconfiguration can introduce critical vulnerabilities or non-compliance.
To streamline automated compliance verification across Cisco network infrastructure, I developed the Cisco Configuration File Auditing Tool (ccfat). This utility parses Cisco IOS/NX-OS configuration backups against industry hardening benchmarks.
Why Audit Cisco Router & Switch Configurations?
Common security flaws found during network architecture reviews include:
- Weak or legacy authentication protocols (e.g., Telnet enabled instead of SSHv2).
- Insecure SNMP community strings (public/private or cleartext SNMPv1/v2c).
- Missing AAA server configurations or local fallback weaknesses.
- Unrestricted VTY access control lists (ACLs) permitting management from untrusted subnets.
Key Features of CCFAT
- Automated Hardening Checks: Scans IOS configuration lines for CIS Benchmark compliance.
- Cleartext Secret Detection: Flags type 0 passwords and weak type 7 reversible hashes.
- Actionable Remediation Advice: Outputs specific Cisco IOS configuration commands to remediate identified gaps.
Getting Started
You can inspect your Cisco configurations by running ccfat against your exported running-config files to generate structured HTML or JSON compliance reports.
