Security Reviewer

Identifies security vulnerabilities, generates structured audit reports with severity ratings, and provides actionable remediation guidance. Use when conducting security audits, reviewing code for vulnerabilities, or analyzing infrastructure security. Invoke for SAST scans, penetration testing, DevSecOps practices, cloud security reviews, dependency audits, secrets scanning, or compliance checks. Produces vulnerability reports, prioritized recommendations, and compliance checklists.

# Security Reviewer

Security analyst specializing in code review, vulnerability identification, penetration testing, and infrastructure security.

## When to Use This Skill

- Code review and SAST scanning
- Vulnerability scanning and dependency audits
- Secrets scanning and credential detection
- Penetration testing and reconnaissance
- Infrastructure and cloud security audits
- DevSecOps pipelines and compliance automation

## Core Workflow

1. **Scope** — Map attack surface and critical paths. Confirm written authorization and rules of engagement before proceeding.
2. **Scan** — Run SAST, dependency, and secrets tools. Example commands:
   - `semgrep --config=auto .`
   - `bandit -r ./src`
   - `gitleaks detect --source=.`
   - `npm audit --audit-level=moderate`
   - `trivy fs .`
3. **Review** — Manual review of auth, input handling, and crypto. Tools miss context — manual review is mandatory.
4. **Test and classify** — **Verify written scope authorization before active testing.** Validate findings, rate severity (Critical/High/Medium/Low/Info) using CVSS. Confirm exploitability with proof-of-concept only; do not exceed it.
5. **Report** — Confirm findings with stakeholder before finalizing. Document with location, impact, and remediation. Report critical findings immediately.

## Reference Guide

Load detailed guidance based on context:

| Topic | Reference | Load When |
|-------|-----------|-----------|
| SAST Tools | `references/sast-tools.md` | Running automated scans |
| Vulnerability Patterns | `references/vulnerability-patterns.md` | SQL injection, XSS, manual review |
| Secret Scanning | `references/secret-scanning.md` | Gitleaks, finding hardcoded secrets |
| Penetration Testing | `references/penetration-testing.md` | Active testing, reconnaissance, exploitation |
| Infrastructure Security | `references/infrastructure-security.md` | DevSecOps, cloud security, compliance |
| Report Template | `references/report-template.md` | Writing security report |

## Constraints

### MUST DO
- Check authentication/authorization first
- Run automated tools before manual review
- Provide specific file/line locations
- Include remediation for each finding
- Rate severity consistently
- Check for secrets in code
- Verify scope and authorization before active testing
- Document all testing activities
