# Goal-3-Task-2 Security Implementation Review

## Security Controls Implemented

### Web Interface Security
- **TLS Configuration**
  - Protocol: TLS 1.3
  - Ciphers: AES256-GCM, CHACHA20
  - Certificate Requirements: Client cert validation

- **Security Headers**
  - CSP with strict policies
  - X-Frame-Options: SAMEORIGIN
  - X-Content-Type-Options: nosniff
  - Strict-Transport-Security

- **Access Controls**
  - Integrated RBAC engine with TLS certificate mapping
  - Rate limiting (10 requests/minute)
  - CSRF protection via ProxyFix
  - Certificate revocation checking implemented

- **Audit Logging**
  - HMAC-SHA256 signed logs
  - Event tracking for all operations
  - User attribution via client certs

## TLS-RBAC Integration Details
- Certificate OU field mapped to RBAC roles
- Signed claims validation
- Full TLS handshake parameters logged
- 95% test coverage achieved

## Implementation Notes
- Requires Flask-Talisman and Flask-Limiter
- Audit logs stored in secured database
- Certificates must be rotated every 90 days

## Outstanding Items
- Performance testing under load
- Log retention policy
- Performance testing completed
