Implement a Content Security Policy (CSP) to mitigate the risk of Cross-Site Scripting (XSS) attacks and other code injection vulnerabilities.

21. Monitor Third-Party Plugins and Extensions

Regularly audit and update third-party plugins and extensions used on your web server to avoid potential security flaws in outdated versions.

22. Implement HTTP Security Headers

Enforce HTTP security headers, such as HTTP Strict Transport Security (HSTS) and X-Content-Type-Options, to enhance the overall security posture of your web server.

23. Secure Email Communication

Encrypt sensitive email communications and implement Domain-based Message Authentication, Reporting, and Conformance (DMARC) to prevent email spoofing.

24. Incident Response Plan

Develop a comprehensive incident response plan to effectively handle security incidents and minimize their impact on your web server and business operations.

25. Regular Security Assessment and Improvement

Never consider your web server security as a one-time task. Continuously assess and improve security measures to stay ahead of emerging threats.
