Complete WordPress Hardening Guide: 15 Security Tweaks
Master WordPress hardening with 15 essential security configurations. Reduce your attack surface and protect your site from common vulnerabilities.
WordPress hardening is the process of configuring your site to minimize security vulnerabilities. By reducing your attack surface, you make it significantly harder for attackers to compromise your site.
What is WordPress Hardening?
Hardening involves:
- Disabling unnecessary features
- Removing information disclosure
- Restricting dangerous capabilities
- Adding protective headers
- Limiting access to sensitive areas
Essential Hardening Steps
1. Hide WordPress Version
WordPress version is displayed in page source and meta tags. Attackers use this to target version-specific vulnerabilities.
Action: Remove version from HTML, RSS feeds, and scripts.
2. Disable XML-RPC
XML-RPC allows remote publishing but is heavily exploited for brute force and DDoS attacks.
Action: Disable completely unless you need mobile apps or Jetpack.
3. Block Pingbacks and Trackbacks
Pingbacks can be used for DDoS amplification and spam.
Action: Disable pingbacks and trackbacks completely.
4. Protect REST API
The REST API exposes user information and can leak sensitive data.
Action: Restrict REST API to authenticated users or disable user endpoints.
5. Disable File Editor
The built-in theme/plugin editor can be used by attackers with admin access to inject malware.
Action: Disable file editing from dashboard.
6. Block User Enumeration
Attackers can discover usernames through author archives and REST API.
Action: Block user enumeration methods.
7. Add Security Headers
- X-Frame-Options: Prevent clickjacking
- X-Content-Type-Options: Prevent MIME sniffing
- X-XSS-Protection: Enable browser XSS filter
- Referrer-Policy: Control referrer information
8. Disable Application Passwords
Application passwords can bypass 2FA. Disable if not needed.
9. Remove Unnecessary Headers
Remove X-Powered-By, X-Pingback, and other revealing headers.
10. Protect wp-config.php
Block direct access to your configuration file.
11. Disable Directory Browsing
Prevent visitors from listing directory contents.
12. Block PHP in Uploads
Prevent PHP execution in wp-content/uploads.
13. Secure Database Prefix
Use a custom database prefix instead of default wp_.
14. Limit Login Attempts
Block brute force attacks by limiting failed logins.
15. Enable HTTPS
Use SSL/TLS for all connections.
