- 4. Configuration Management
- 5. Updates and patches
- 6. Event Logging and Auditing (for performance and security)
- 7. Managing System Services
- 8. Virtualization
- 9. Backup and Restoring Data
- 10. File System Security
- 11. Network Configuration (port security)
- 12. Host (Workstation/Server) Intrusion Detection
- 13. Security Policy Development
- Setting up user accounts
- Configuring appropriate authentication policies
