Plan authorized security reviews with threat modeling, architecture and dependency audits, and vulnerability classification. Use for scoped defensive security assessment. Do not use for offensive operations, unauthorized testing, or security control implementation.

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.

What the file says

# Security Audit Methodology

## Authorization and safety boundary

Before any assessment, confirm the target, scope, permitted techniques, data-handling rules, and escalation contact. Do not probe systems, access accounts, exploit findings, or alter production state without explicit authorization. Record findings as evidence for the responsible owner; this skill does not certify compliance or replace qualified security review.

Security is not a checklist — it's a posture. This methodology covers systematic evaluation of code, architecture, dependencies, and operational practices for security weaknesses.

## The Security Engineer's Domain

| You own | You don't own |
|---------|--------------|
| Threat modeling — STRIDE, attack trees, trust boundaries | General code review — that's the qa-methodology |
| Vulnerability assessment — classification, severity, reproduction | Performance analysis — that's the systematic-debugging |
| Security architecture review — authn/authz, data flow, secrets management | Operational reliability — that's SRE |
| Dependency analysis — supply chain, known vulnerabilities, license risk | Compliance certification — that's legal |

How to install

The exact contents, by fingerprint
mdr add magnus919/agent-skills/security-audit-methodology@sha256:f91e11e3fcdc5e43

The line at the top of this page pins the label git:20260803.0223e2b, 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.
