WordPress Security Hardening

WordPress Security Hardening

WordPress is a popular target for hackers due to its widespread use. Implementing security hardening measures significantly reduces your risk of being compromised. Follow these steps to protect your site.

Keep Everything Updated

The most important security measure is keeping WordPress core, themes, and plugins updated. Most attacks exploit known vulnerabilities in outdated software.

• Enable automatic updates for minor WordPress releases.
• Update plugins and themes as soon as new versions are available.
• Remove any themes or plugins you no longer use.

Secure the Login Page

• Use strong, unique passwords for all user accounts.
• Change the default username: Never use “admin” as your administrator username.
• Enable Two-Factor Authentication (2FA): Require a second verification step at login.
• Limit login attempts: Use a plugin to block repeated failed login attempts.
• Change the login URL: Move wp-login.php to a custom URL using a plugin like WPS Hide Login.

File and Database Protection

Add these rules to your .htaccess file (Apache) or server configuration:

# Disable directory browsing
Options -Indexes

# Protect wp-config.php
<Files wp-config.php>
Order deny,allow
Deny from all
</Files>

# Protect .htaccess
<Files .htaccess>
Order deny,allow
Deny from all
</Files>

• Change the database table prefix: Use something other than the default wp_ during installation.
• Set proper file permissions: Directories should be 755, files should be 644, and wp-config.php should be 440 or 400.

Additional Hardening Steps

1. Disable file editing: Add define('DISALLOW_FILE_EDIT', true); to wp-config.php to prevent theme/plugin editing from the dashboard.
2. Disable XML-RPC if you don’t use it — it’s a common attack vector.
3. Add security headers: Implement headers like X-Content-Type-Options, X-Frame-Options, and Content-Security-Policy.
4. Use SSL/HTTPS: Encrypt all traffic with an SSL certificate. Most hosts, including 10Corp, offer free Let’s Encrypt certificates.
5. Install a Web Application Firewall (WAF): Plugins like Wordfence or cloud services like Cloudflare filter malicious traffic.

Monitoring and Recovery

• Set up security scanning: Use Wordfence or Sucuri to scan for malware regularly.
• Monitor file changes: Get alerts when core files are modified unexpectedly.
• Maintain regular backups: Store backups offsite so you can restore quickly after an incident.

Security is an ongoing process — review your measures regularly and stay informed about new threats.
