pyats-security

pyats-security is a skill for Claude Code from automateyournetwork/netclaw. It costs 58 tokens per session (2,514 once invoked), scanned A, original, Apache-2.0.

A network-security audit skill for reviewing router and switch configurations against security practices and compliance benchmarks.

In plain words
What is it for?
Use it to audit ACLs, AAA, control-plane policing, encryption, port security, management-plane hardening, and CIS, NIST, SOC 2, or PCI-DSS checks.
Why use it?
It helps expose weak management access, unsafe settings, missing controls, and signs of unauthorized access before they become larger problems.

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

pyats-security 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 9d 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.

Network Security Audit

When to Use

  • Security posture assessment for compliance (SOC2, PCI-DSS, NIST, CIS)
  • Pre-deployment security review
  • Incident response — checking for unauthorized access or configuration
  • Hardening audit for new devices
  • Periodic security validation

Security Audit Procedure

Step 1: Pull Running Configuration

Always start by capturing the full running config for analysis:

PYATS_TESTBED_PATH=$PYATS_TESTBED_PATH python3 $MCP_CALL "${PYATS_PYTHON:-python3} -u $PYATS_MCP_SCRIPT" pyats_show_running_config '{"device_name":"R1"}'

Scan the full config for the checks below.

Step 2: Management Plane Hardening

Check these items in the running config:

Check What to Look For Finding If Missing
SSH version ip ssh version 2 CRITICAL: SSHv1 vulnerable to MITM
Telnet disabled No transport input telnet on VTY lines CRITICAL: Telnet sends cleartext credentials
VTY ACL access-class on VTY lines HIGH: Unrestricted management access
Console timeout exec-timeout on console (not 0 0) MEDIUM: Unattended console sessions
VTY timeout exec-timeout on VTY lines (not 0 0) MEDIUM: Stale management sessions
Password encryption service password-encryption MEDIUM: Type 0 passwords visible
Enable secret enable secret (not enable password) HIGH: Enable password uses weak hash
Login banner banner login or banner motd LOW: Legal/compliance requirement
HTTP server disabled no ip http server MEDIUM: Unnecessary attack surface
HTTPS server ip http secure-server if web management needed MEDIUM: Use HTTPS not HTTP
Aux port disabled no exec on aux line LOW: Unused port open

Step 3: AAA Configuration

PYATS_TESTBED_PATH=$PYATS_TESTBED_PATH python3 $MCP_CALL "${PYATS_PYTHON:-python3} -u $PYATS_MCP_SCRIPT" pyats_run_show_command '{"device_name":"R1","command":"show aaa servers"}'

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.
