Documentation

README

Excerpt

VPN Infrastructure Security Audit

Checks that the VPN server is properly hardened. All checks run via ssh_exec.py — no additional tools needed.

When to Use

User asks about security: "check security", "is my VPN safe"
After initial deployment (offer proactively)
User has security concerns
Periodic security checkup

The Iron Law

EVERY CHECK MUST RUN A COMMAND. NO ASSUMPTIONS.

"quick-rebuild.sh enables the firewall" is not evidence that the firewall is active. Run the check.

Security Checks

Run ALL checks in order. Report each as PASS/FAIL/WARN with evidence.

1. SSH Hardening

1a. SSH Port

Command: python ssh_exec.py exec "grep -E '^Port ' /etc/ssh/sshd_config"
