network-audit

network-audit is a command for Claude Code from HermeticOrmus/LibreSecOps-Claude-Code. It costs 25 tokens per session (1,086 once invoked), scanned A, original, MIT.

A guided network security audit that reviews firewalls, network separation, internet exposure, VPNs, and monitoring. It can use configuration files, network diagrams, cloud settings, or live system checks.

In plain words
What is it for?
Use it to review firewall configurations, check network zones and traffic paths, inspect VPN or tunnel settings, and assess monitoring and intrusion-detection coverage.
Why use it?
It helps reveal services that should not be reachable, weak firewall rules, and paths an intruder could use to move between systems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

network-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/network-audit

Structured audit of network configuration covering firewalls, segmentation, exposure, and monitoring.

Trigger

Use when you need to:

  • Review firewall rules (iptables, nftables, cloud security groups) for security
  • Assess network segmentation and lateral movement risk
  • Identify unnecessary network exposure
  • Audit VPN or tunnel configurations
  • Evaluate network monitoring and IDS/IPS coverage

Input

One or more of:

  • Firewall rules: iptables-save output, nft list ruleset output, cloud security group exports
  • Network diagram: Topology showing segments, trust zones, and traffic flows
  • Live system access: SSH access to hosts for ss, iptables-save, ip route inspection
  • Cloud configuration: Terraform files defining security groups/NSGs/firewall rules
  • Specific scope: Focus area (e.g., "DMZ security", "internal segmentation", "VPN config")

Process

Phase 1: Topology & Exposure

  1. External attack surface

    • Internet-facing IP addresses and services
    • Open ports visible from the internet (authorized scan or cloud config review)
    • Services that should NOT be internet-facing (databases, admin panels, monitoring)
    • Management interfaces (SSH, RDP) accessible from internet
  2. Network segments

    • Identified trust zones (public, DMZ, internal, management, database)
    • Inter-zone firewall rules
    • Flat network segments (no internal firewalling)
    • VLAN configuration and trunk security

Phase 2: Firewall Rules

  1. Rule assessment

    • Default policy (ACCEPT is a critical finding for INPUT/FORWARD chains)
    • Rules allowing 0.0.0.0/0 ingress (any source)
    • Rules allowing broad port ranges or any port
    • Rules with no logging
    • Orphaned rules (reference dead IPs or decommissioned services)
    • Rule ordering (iptables processes sequentially -- early broad allows bypass later specific denies)
  2. Egress filtering

    • Outbound traffic restrictions (default allow outbound is common and dangerous)
    • Permitted outbound ports (HTTP/HTTPS/DNS are common, but should be the only allowed)
    • Data exfiltration paths (can internal hosts send arbitrary traffic outbound?)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

network-audit is a command published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 9d ago), licensed MIT. It adds 25 tokens to every session and 1,086 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
