- **DDoS Protection:** Employ firewalls and DDoS mitigation services to protect game servers from attacks.
- **Regular Audits:** Conduct security audits and penetration testing to identify and fix vulnerabilities.

### **4.3. Maintainability**

- **Modular Design:** Structure the codebase and system components into modular, reusable modules to simplify updates and debugging.
- **Documentation:** Maintain comprehensive documentation for all components, APIs, and workflows to facilitate team collaboration and onboarding.
- **Automated Testing:** Implement automated unit, integration, and end-to-end tests to ensure code quality and facilitate continuous integration.
- **Version Control:** Use version control systems (e.g., Git) with branching strategies to manage code changes effectively.
- **Continuous Monitoring:** Monitor system performance and health using monitoring tools, enabling proactive maintenance and issue resolution.
