Audit normalized Cisco, Fortinet, Palo Alto, and Juniper firewall rulebases for security hygiene. Use when finding any-any, shadowed, redundant, or orphaned rules, missing deny or logging, exposed management, weak VPN crypto, hardening gaps, or unused objects. Parse raw configs first.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## Overview

Use this skill to audit a firewall or NGFW rulebase for security and operational hygiene, vendor-neutrally, over the `parsing-*` intermediate JSON schema. The audit reads normalized `security_policies`, `nat_rules`, address/service objects and groups, `zones`, `vpn_tunnels`, `system`, and `admin_users`, then emits prioritized findings across the security and operational check families (full catalog: `references/check-catalog.md`). Each finding carries a severity, a confidence, the affected references, why it matters, and remediation.

How to install

The exact contents, by fingerprint
mdr add mechubsec/fwskillsshare/firewall-best-practices-audit@sha256:87dbc5c753a40a9e

The line at the top of this page pins the label v1.3.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
