WordPress Security Guide: 15 Essential Steps

Why is WordPress a Target?

43% of the world's websites = millions of similar vulnerabilities. One vulnerable plugin = millions of potential victims. Bots are scanning constantly.

15 Steps to Protect WordPress

1. Update Everything WordPress core, plugins, and themes. 60% of hacks result from outdated software.

2. Remove Unused Plugins and Themes Even inactive plugins serve as attack vectors.

3. Strong Admin Password + 2FA WP 2FA plugin (free). Google Authenticator.

4. Change the Admin Username "admin" is the first one a bot tries. Create a new admin user and delete the old one.

5. Change the Login URL WPS Hide Login plugin. /wp-admin → /secure-login

6. Limit Login Attempts Use the "Limit Login Attempts Reloaded" plugin. 3 failed attempts = IP blocked.

7. Disable XML-RPC `xmlrpc.php` is a frequent attack vector. If you don't use it, block it.

8. Disable File Editing in the Admin Panel Add to `wp-config.php`: `define('DISALLOW_FILE_EDIT', true);`

9. Correct File Permissions - Files: 644 - Directories: 755 - wp-config.php: 600

10. Database Prefix The default is `wp_`. Change it to `wp_xY9k_` or similar. Recommended plugin: iThemes Security.

11. Web Application Firewall (WAF) - Wordfence (free tier) - Sucuri (paid) - Cloudflare WAF

12. Whitelist Only Local IPs for Admin Panel Wordfence Country Blocking.

13. SSL Certificate Let's Encrypt, free.

14. Daily Backups UpdraftPlus + Google Drive. 90-day retention.

15. Malware Scanning Wordfence or Sucuri SiteCheck. Run weekly.
