# Goal-1-Task-4 Security Review

## Version Control Configuration Security Assessment

### Verified Controls:
✅ **Authentication Security**
- TLS 1.3 with modern ciphers (AES256-GCM)
- Client certificate pinning implemented
- Signed OU claims for role mapping

✅ **Authorization Controls**  
- RBAC with boundary enforcement (GLOBAL/INTERNAL/RESTRICTED)
- Least privilege principle enforced
- Admin-only merge requirement

✅ **Data Protection**  
- AES-256 artifact encryption
- HMAC-SHA256 audit log integrity
- Signed SBOMs (CycloneDX format)

### Recommendations:
1. Consider adding automated rotation for HMAC keys (currently manual)
2. Document certificate pinning exceptions process
3. Add periodic review of RBAC role assignments

### Status: APPROVED
All security requirements met with proper implementation.
