Security Audit

4-phase security audit covering supply chain risks, OWASP Top 10 code review, STRIDE threat modeling, and trend-tracked reporting. Produces structured JSON findings in .workflow/.security/.

Architecture Overview

+-------------------------------------------------------------------+
|  Phase 1: Supply Chain Scan                                       |
|  -> Dependency audit, secrets detection, CI/CD review, LLM risks  |
|  -> Output: supply-chain-report.json                              |
+-----------------------------------+-------------------------------+
                                    |
+-----------------------------------v-------------------------------+
|  Phase 2: OWASP Review                                           |
|  -> OWASP Top 10 2021 code-level analysis via ccw cli            |
|  -> Output: owasp-findings.json                                  |
+-----------------------------------+-------------------------------+
                                    |
+-----------------------------------v-------------------------------+
|  Phase 3: Threat Modeling (STRIDE)                                |
|  -> 6 threat categories mapped to architecture components         |
|  -> Output: threat-model.json                                    |
+-----------------------------------+-------------------------------+
                                    |
+-----------------------------------v-------------------------------+
|  Phase 4: Report & Tracking                                      |
|  -> Score calculation, trend comparison, dated report             |
|  -> Output: .workflow/.security/audit-report-{date}.json         |

Key Design Principles

1. Infrastructure-first: Phase 1 catches low-hanging fruit (leaked secrets, vulnerable deps) before deeper analysis
2. Standards-based: OWASP Top 10 2021 and STRIDE provide systematic coverage
3. Scoring gates: Daily quick-scan must score 8/10; comprehensive audit minimum 2/10 for initial baseline
4. Trend tracking: Each audit compares against prior results in .workflow/.security/

Execution Flow

Quick-Scan Mode (daily)

Run Phase 1 only. Must score >= 8/10 to pass.

Comprehensive Mode (full audit)

Run all 4 phases sequentially. Initial baseline minimum 2/10.

Phase Sequence

1. Phase 1: Supply Chain Scan -- phases/01-supply-chain-scan.md
   • Dependency audit (npm audit / pip-audit / safety check)
   • Secrets detection (API keys, tokens, passwords in source)
   • CI/CD config review (injection risks in workflow YAML)
   • LLM/AI prompt injection check
2. Phase 2: OWASP Review -- phases/02-owasp-review.md
   • Systematic OWASP Top 10 2021 code review
   • Uses ccw cli --tool gemini --mode analysis --rule analysis-assess-security-risks
3. Phase 3: Threat Modeling -- phases/03-threat-modeling.md
   • STRIDE threat model mapped to architecture components
   • Trust boundary identification and attack surface assessment
4. Phase 4: Report & Tracking -- phases/04-report-tracking.md
   • Score calculation with severity weights
   • Trend comparison with previous audits
   • Date-stamped report to .workflow/.security/

Scoring Overview

See specs/scoring-gates.md for full specification.

| Severity | Weight | Example | |----------|--------|---------| | Critical | 10 | RCE, SQL injection, leaked credentials | | High | 7 | Broken auth, SSRF, privilege escalation | | Medium | 4 | XSS, CSRF, verbose error messages | | Low | 1 | Missing headers, informational disclosures |

Gates: Daily quick-scan >= 8/10, Comprehensive initial >= 2/10.

Completion Status Protocol

This skill follows the Completion Status Protocol defined in _shared/SKILL-DESIGN-SPEC.md sections 13-14.

Possible termination statuses:

• DONE: All phases completed, score calculated, report generated
• DONE_WITH_CONCERNS: Audit completed but findings exceed acceptable thresholds
• BLOCKED: Required tools unavailable (e.g., npm/pip not installed), permission denied
• NEEDS_CONTEXT: Ambiguous project scope, unclear trust boundaries

Escalation follows the Three-Strike Rule (section 14) per step.
