WordPress is the most targeted CMS on the web. Here are the essential security measures every WordPress site should have in place.
WordPress powers over 43% of all websites on the internet. That ubiquity makes it the most targeted CMS for hackers. The good news? The vast majority of WordPress hacks are preventable with basic security hygiene. Here's everything you need to know to keep your site safe.
The reality of WordPress security
Let's be clear: WordPress core is actually very secure. The WordPress security team includes some of the best developers in the world, and the codebase undergoes constant scrutiny. The overwhelming majority of WordPress hacks exploit weak passwords, outdated plugins, or misconfigured hosting - not vulnerabilities in WordPress itself.
Essential security measures
1. Strong passwords and user management
It sounds basic, but weak passwords remain the most common attack vector. Use unique, complex passwords for every admin account and enforce strong password policies for all users. Implement two-factor authentication (2FA) for all admin accounts - plugins like WP 2FA or Wordfence make this straightforward.
2. Keep everything updated
Outdated software is the second most common cause of hacks. Keep WordPress core, themes, and plugins updated at all times. Enable automatic updates for minor releases and monitor major updates closely. Remove any plugins or themes you're not using - they're unnecessary attack surface.
3. Secure your hosting
Your hosting environment is your first line of defence. Choose a reputable WordPress hosting provider that offers server-level firewalls, malware scanning, and automatic backups. Managed WordPress hosts like WP Engine, Kinsta, or Flywheel handle much of the security configuration for you.
- Use SSL/TLS certificates (HTTPS) - non-negotiable in 2023
- Disable XML-RPC if you're not using it
- Change the default admin username from 'admin'
- Limit login attempts to prevent brute force attacks
- Implement a Web Application Firewall (WAF)
- Schedule regular backups stored off-site
- Use security headers (CSP, X-Frame-Options, etc.)
Security plugins worth considering
Wordfence and Sucuri are the two most established WordPress security plugins. Both offer firewalls, malware scanning, and login security features. For smaller sites, iThemes Security (now SolidWP) provides a good balance of protection without overwhelming complexity.
Security isn't a product, it's a process. No single plugin or configuration makes you 'secure' - it's the ongoing combination of good practices that keeps your site safe.
