Security Checklist

This guides your security review methodology. You scan new/changed code for vulnerabilities using two frameworks: OWASP Top 10 (specific vulnerability categories) and STRIDE (threat modeling).

Review Scope

Focus on code that was created or modified in this factory run. Use Cyborg's briefings (.factory-run/briefings/cyborg-*.json) to identify which files changed. Don't audit the entire codebase — that's noise, not signal.

For each changed file, assess:

• Does it handle user input?
• Does it interact with databases, filesystems, or external services?
• Does it handle authentication or authorization?
• Does it expose data to the client?

Files that do none of these are low-risk. Spend your time on the ones that do.

OWASP Top 10 Scan

For each category, check the changed code for common patterns. See references/owasp-top-10.md for detailed patterns to look for in each category. Use the Read tool to load this file — it is not auto-loaded with the skill.

Quick reference:

• A01: Broken Access Control — Missing auth checks, IDOR, privilege escalation
• A02: Cryptographic Failures — Weak algorithms, hardcoded keys, plaintext storage
• A03: Injection — SQL, NoSQL, OS command, LDAP injection
• A04: Insecure Design — Missing rate limiting, no abuse controls
• A05: Security Misconfiguration — Debug mode, default credentials, overly permissive CORS
• A06: Vulnerable Components — Known-vulnerable dependencies
• A07: Auth Failures — Weak password rules, missing brute-force protection
• A08: Data Integrity — Unsigned updates, insecure deserialization
• A09: Logging Failures — Missing audit logs, logging sensitive data
• A10: SSRF — Unvalidated URL fetching, internal service access

STRIDE Threat Analysis

For the feature as a whole, consider each STRIDE category. See references/stride.md for detailed guidance. Use the Read tool to load this file — it is not auto-loaded with the skill.

• Spoofing — Can an attacker pretend to be someone else?
• Tampering — Can data be modified in transit or at rest?
• Repudiation — Can actions be performed without accountability?
• Information Disclosure — Can sensitive data leak?
• Denial of Service — Can the feature be abused to degrade service?
• Elevation of Privilege — Can a user gain unauthorized access?

Secrets Scan

Grep for common secret patterns in changed files:

• API keys, tokens, passwords in code or config
• Private keys, certificates
• Connection strings with credentials
• Patterns: password=, secret=, api_key=, token=, -----BEGIN

Output Field Names

Your output JSON MUST use these exact field names to pass schema validation:

{
  "verdict": "pass",
  "summary": "...",
  "owasp_findings": [],
  "stride_analysis": {
    "spoofing": [],
    "tampering": [],
    "repudiation": [],
    "information_disclosure": [],
    "denial_of_service": [],
    "elevation_of_privilege": []
  },
  "secrets_scan": {
    "clean": true,
    "findings": []
  }
}

Do NOT use alternative names like findings, owasp_check, or owasp_results. The PostToolUse validation hook will reject the write if field names don't match the schema.

Severity Guide

• Critical: Exploitable vulnerability with direct impact (SQL injection, exposed credentials, missing auth on sensitive endpoint)
• High: Vulnerability that requires some conditions to exploit but would have significant impact
• Medium: Security weakness that should be addressed but isn't immediately exploitable
• Low: Best practice violation with minimal direct risk

Only critical and high cause a "fail" verdict.
