Goal-6-Task-2 Security Validation Report

Security Assessment (2025-05-04)

1. RBAC Implementation Validation

✅ Verified:

• Core RBAC engine tests (test_rbac_engine.py)
• Permission validation (lines 51-60 in test report)

⚠️ Missing:

• Event framework integration tests
• Role-based event type restrictions
• Publisher/subscriber permission validation

2. Event Security Boundaries

✅ Verified:

• Basic payload validation (test_core.py lines 36-41)
• Event type validation (test_core.py lines 29-34)

⚠️ Missing:

• Sender authentication verification
• Boundary enforcement between event domains
• Encrypted payload integration (AES-256)

3. Test Coverage Completeness

Coverage Gaps:

1. Security Integration:

   • No tests for encrypted event payloads
   • Missing key rotation scenarios
   • No negative tests for invalid security tokens

2. RBAC Integration:

   • No role-based event filtering
   • Missing permission escalation tests
   • No audit logging verification

Critical Recommendations

1. Immediate Actions:

   • Add RBAC integration tests (events + security)
   • Implement encrypted payload tests
   • Verify boundary enforcement

2. Test Cases Required:

# Example test case needed:
def test_unauthorized_event_publishing():
    """Verify RBAC prevents unauthorized event publishing"""
    with pytest.raises(PermissionError):
        publish_event(event_type="restricted", 
                     payload={}, 
                     user=low_privilege_user)

3. Documentation Updates:
   • Add security requirements to architecture.md
   • Document encryption integration pattern
   • Update threat model with event boundaries

Validation Status

Conditional Approval - Core security mechanisms exist but require integration testing before production deployment.

Next Steps:

1. Implement integration tests
2. Verify encryption/RBAC integration
3. Revalidate before 2025-05-06 deadline
