# 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**:
```python
# 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
