1. Keep Everything Updated
The #1 cause of WordPress compromises is outdated software. Always update WordPress core, all plugins, and themes immediately when updates are available. Enable automatic updates for minor releases. Remove plugins and themes you're not using – inactive plugins can still be vulnerable.
2. Strong Authentication
Use strong passwords (12+ characters with symbols). Never use the default admin username – create a unique one. Enable two‑factor authentication (2FA) using plugins like Wordfence, Google Authenticator, or Duo. Limit login attempts to prevent brute‑force attacks.
3. Use a Security Plugin
Install a comprehensive security plugin like Wordfence, iThemes Security, or Sucuri. These plugins provide: firewall protection, malware scanning, login security, file integrity monitoring, and many other features. OffURL can detect common WordPress vulnerabilities even without a security plugin.
4. Hardening WordPress
Change the default `wp_` table prefix. Disable file editing in the WordPress admin (define `DISALLOW_FILE_EDIT`). Move `wp-config.php` one level above the webroot. Disable directory listing and XML‑RPC if not needed. Use `Security-Headers` like CSP and HSTS.
The Problem
