# Goal-5: Security Implementation Execution Plan

## Implementation Phases

### 1. Role Inheritance System
- **Task 5.1**: Extend RBAC Engine in `security/rbac_engine.py`
  - Implement role hierarchy/inheritance
  - Add permission propagation logic
  - Update test cases in `tests/security/test_rbac_engine.py`
- **Task 5.2**: Integrate with Role Manager
  - Modify `orchestrator/core/dispatcher.py` to use enhanced RBAC
  - Update CLI/web interfaces for role management
- **Validation**: 
  - Security review of implementation
  - Negative test cases in `tests/security/test_rbac_negative.py`

### 2. Secrets Management Service
- **Task 5.3**: Design secrets storage
  - Create `security/secrets.py` module
  - Implement AES-256 encryption using existing `security/encrypt.py`
  - Add key rotation mechanism
- **Task 5.4**: Implement API
  - Create REST endpoints in `web_interface.py`
  - Add CLI commands in `cli_commands.py`
- **Validation**:
  - Penetration testing of secrets API
  - Audit logging integration

### 3. Automated Vulnerability Scanning
- **Task 5.5**: Implement scanner core
  - Create `security/scanner.py` module
  - Integrate with MCP Manager for external tools
  - Add scheduling capability
- **Task 5.6**: Create reporting
  - Generate vulnerability reports
  - Implement severity classification
  - Add integration with audit logs
- **Validation**:
  - Test with known vulnerabilities
  - Verify false positive rate

## Dependencies
- Goal-1 (Orchestrator Core) must be 75% complete
- Goal-4 (Storage Layer) must be 100% complete

## Timeline
- Week 1: Role inheritance implementation
- Week 2: Secrets management service
- Week 3: Vulnerability scanning
- Week 4: Integration and testing

## Security Controls
1. All changes must pass security review
2. Audit logs must capture all security-sensitive operations
3. Automated tests must cover all security-critical paths
4. Documentation must be updated in `symphony-ai-agent/security/`

## Implementation Status

1. Role inheritance system: Implemented (see tests/security/test_rbac_engine.py)
2. Secrets management service: Not started
3. Automated vulnerability scanning: Not started
