20. Regularly Check for Vulnerabilities: – Keep an eye on security news and subscribe to vulnerability alerts related to WordPress. Act promptly to address any known vulnerabilities.
21. Security Headers: – Implement security headers, such as Content Security Policy (CSP), X-Content-Type-Options, and X-Frame-Options, to mitigate security risks.
22. Disable PHP Execution in Untrusted Directories: – Disable PHP execution in directories where it’s not required. Add the following line to your .htaccess file: php_flag engine off.
23. Lock Down .htaccess File: – Protect your .htaccess file by making it read-only. This prevents unauthorized modifications.
24. Regularly Review User Permissions:
- Periodically review the user roles and permissions of individuals who have access to your WordPress site. Ensure that users have the appropriate level of access, and remove any unnecessary or outdated accounts.
25. Implement a Content Delivery Network (CDN):
- A CDN can help distribute the load of your website and provide an extra layer of security by filtering out malicious traffic and reducing the risk of DDoS attacks.
26. Monitor for Brute Force Attacks:
- Use security plugins or server-side tools to monitor and block brute force login attempts in real-time. This helps protect your site from unauthorized access.
27. Regularly Audit Your Site’s Code:
- Conduct a thorough code audit to identify and remove any unnecessary or potentially vulnerable code in your themes and plugins.
28. Set Up a Firewall:
- Implement a website firewall, which can help protect your site from various types of attacks, including SQL injection and cross-site scripting (XSS) attacks.
29. Use a Strong Hosting Provider:
- Choose a reputable hosting provider that specializes in WordPress hosting and offers security features such as regular malware scans and server-side firewalls.
30. Disaster Recovery Plan:
- Develop a disaster recovery plan that outlines how to restore your site in case of a security breach. This plan should include detailed steps for recovering data and regaining control of your website.
31. Stay Informed about Security Threats:
