Building a Cisco ASA Firewall Review Tool in a Day with AI
·11 mins
From an empty repository to a useful Cisco ASA firewall review tool in about a day. Here is how it works, and where I had to overrule the AI.
TL;DR # I built an offline, read-only tool that reviews a Cisco ASA firewall configuration and reports security findings. Point it at a show running-config dump and it returns a prioritized report: insecure management access, weak or deprecated crypto, overly permissive access rules, missing logging and hardening, and cleartext secrets. Every finding is backed by the exact config line that proves it, or a clear marker when the problem is a missing setting. The review runs entirely on your machine, with no internet and no device access, so nothing leaves the host. The tool is public at github.com/cutaway-security/cisco-asa-review.
