How to Perform a Manual Security Hardening of Your WordPress Installation

Securing your WordPress site is essential to protect it from hackers and malicious attacks. Manual security hardening involves configuring settings and implementing best practices to enhance your website’s defenses. This guide provides step-by-step instructions to help you strengthen your WordPress installation.

1. Keep WordPress, Themes, and Plugins Updated

Regularly updating your WordPress core, themes, and plugins ensures you have the latest security patches. Outdated software can be vulnerable to exploits. Always back up your site before performing updates.

2. Remove Unused Themes and Plugins

Deactivate and delete any themes and plugins that are not in use. This reduces potential entry points for attackers and minimizes the attack surface of your site.

3. Configure File Permissions

Set correct file permissions to prevent unauthorized access. Recommended permissions are 644 for files and 755 for directories. Use your hosting control panel or command line to adjust permissions.

4. Disable Directory Listing

Prevent attackers from viewing directory contents by disabling directory listing via your server configuration. For Apache, add Options -Indexes to your .htaccess file.

5. Implement Strong Passwords and User Roles

Use complex, unique passwords for all user accounts. Assign appropriate roles, and avoid giving unnecessary administrative privileges to users. Consider using a password manager to generate and store passwords securely.

6. Enable Two-Factor Authentication (2FA)

Adding 2FA adds an extra layer of security. Use plugins like Google Authenticator or Authy to enable 2FA for all user accounts, especially administrators.

7. Limit Login Attempts

Restrict the number of login attempts to prevent brute-force attacks. Many security plugins offer this feature, or you can configure server rules to limit attempts.

8. Use HTTPS with SSL/TLS

Encrypt data transmitted between your website and visitors by installing an SSL certificate. Many hosting providers offer free SSL certificates via Let’s Encrypt. Update your site URL to use https://.

9. Protect wp-config.php and .htaccess Files

Restrict access to sensitive files by adding rules to your .htaccess file. For example:



Order deny,allow
Deny from all

10. Regular Backups and Monitoring

Maintain regular backups of your website and database. Use trusted backup plugins and store backups securely off-site. Monitor your site for unusual activity and scan for malware periodically.

Conclusion

Manual security hardening is an ongoing process that requires diligence. Implement these best practices to significantly improve your WordPress site’s security and protect your online presence from threats.
