Version Control Security Audit Checklist

Core Security Domains

1. Authentication

   • MFA required for lock overrides (Branch Locking.md Line 58)
   • Session invalidation on permission changes

2. Authorization

   • Role hierarchy enforcement (Approval Workflow.md Line 22)
   • Context-sensitive permission checks

3. Data Protection

   • Encryption of comparison metadata (Version Comparison.md Line 6)
   • Audit log integrity verification

4. Workflow Security

   • State machine tamper detection (Approval Workflow.md Line 45)
   • Comment edit history immutability

Threat Mitigation Table

Threat Type	Affected Feature	Mitigation Strategy
Race Conditions	Branch Locking	Optimistic locking with version stamps
XSS	Change Comments	DOMPurify integration (Line 89)
Data Leakage	Version Comparison	Strict field-level encryption
Repudiation	Approval Workflow	Blockchain-style audit trail

Testing Procedures

1. Penetration Tests

   • Lock bypass attempts via API fuzzing
   • Approval state injection attacks

2. Static Analysis

   • OWASP ZAP scan configuration
   • SonarQube security rule activation

3. Runtime Monitoring

   • Unauthorized diff access alerts
   • Abnormal approval pattern detection

Phase Integration

Development Phase	Security Focus
Locking Implementation	Permission model validation
Workflow Development	State transition auditing
Comment System	Content sanitization checks
Comparison Tool	Data anonymization tests

Severity Levels

• Critical: Direct system access vulnerabilities
• High: Data integrity risks
• Medium: UX security weaknesses
• Low: Informational exposure
