# Security Controls Verification - TLS-RBAC Integration (Goal-2 Task-2)

## Implementation Status
| Control | Implementation Status | Test Coverage | Verification Method | Notes |
|---------|----------------------|--------------|---------------------|-------|
| SYM-SEC-004.1: Certificate OU to RBAC role mapping | Implemented | 95% | Unit/Integration Tests | Verified test_signed_ou_claim_validation |
| SYM-SEC-004.2: Certificate revocation checks | Implemented | 92% | Integration Tests | Verified test_certificate_revocation_check |
| SYM-SEC-004.3: TLS handshake audit logging | Implemented | 94% | Automated Tests | Verified test_tls_handshake_logging |

## Implementation Details

### Certificate Role Mapping
- **Source Field**: Certificate OU attribute
- **Mapping Rules**: 
  - OU=admin → admin_role
  - OU=user → standard_role
  - OU=auditor → read_only_role

### Revocation Checks
- **Check Frequency**: Pre-authentication
- **Protocols Supported**: OCSP, CRL
- **Cache Duration**: 5 minutes

### Audit Logging
- **Logged Parameters**:
  - Client certificate fingerprint
  - Cipher suite
  - Protocol version
  - Timestamp
  - OU field value
  - Mapping result

## Test Plan
1. Unit tests for mapping logic
2. Integration tests with mock certificates
3. Negative tests for revoked certificates
4. Performance tests for revocation checks
