WordPress Security
WordPress Hardening
WordPress powers a huge share of the web, which makes it the most targeted CMS. Systematic hardening, updates, least-privilege file permissions, login protection, security headers, and a properly configured security plugin, stops the automated campaigns responsible for most WordPress hacks.
Key points
- Update core, themes, and plugins on a weekly cadence; remove abandoned ones.
- Set directories 755 and files 644; wp-config.php 600 or tighter.
- Move wp-config.php one level above web root where hosting allows.
- Disable file editing in the dashboard and limit login attempts.
- Enforce strong passwords plus 2FA for every administrator.
- Block xmlrpc.php unless a specific integration needs it.
- Add security headers: CSP, HSTS, X-Frame-Options, referrer policy.
- Run a Web Application Firewall (plugin or server-level) in blocking mode.
Field note
Do permissions before plugins: directories 755, files 644, wp-config locked down. Half the 'hacked WordPress' tickets I've worked trace to a single 777 folder someone set 'temporarily'.
Frequently asked questions
Will hardening break my theme or plugins?
Done carefully, no. Changes are staged and verified; file editing and XML-RPC rarely affect legitimate functionality.
Is a security plugin enough?
It's one layer. Updates, permissions, backups, and login policy matter equally.
How often should WordPress be updated?
Weekly for plugins/themes, immediately for security releases, with backups before each run.
Does hardening help SEO?
Indirectly but measurably: clean, fast, HTTPS, always-up sites rank and convert better.
