Essential WordPress Security Checklist for Website Owners

Why You Need a Security Checklist

WordPress security isn't a one-time task—it requires ongoing attention and regular maintenance. A security checklist helps you systematically address all aspects of website protection without overlooking critical areas.

This checklist covers essential security measures that every WordPress site should implement. Whether you're setting up a new site or auditing an existing one, work through each item to ensure comprehensive protection.

Initial Setup Security

Choose Secure Hosting

Your hosting environment forms the foundation of your security. Ensure your host provides:

• PHP version 8.0 or higher
• MySQL 8.0 or MariaDB 10.4+
• SSL/TLS certificates
• Regular server-level security updates
• Malware scanning and removal
• Automated backups

Install SSL Certificate

Every website needs HTTPS encryption. Install an SSL certificate and configure WordPress to use HTTPS for all pages. Update your site URL in Settings > General to use https://.

Use Strong Database Prefix

Change the default "wp_" database prefix to something unique during installation. This prevents automated SQL injection attacks that target default table names.

User Account Security

Create Secure Admin Account

• Never use "admin" as your username
• Use a complex, unique password
• Set up a separate account for publishing content
• Limit the number of administrator accounts

Implement Two-Factor Authentication

Enable 2FA for all users with administrative access. Use TOTP-based authentication with apps like Google Authenticator or Authy.

Review User Roles

Regularly audit user accounts and ensure each user has only the permissions they need. Remove inactive accounts and downgrade unnecessary admin privileges.

Login Security

Change Login URL

Move your login page from the default /wp-login.php to a custom URL. This prevents automated attacks targeting the standard login location.

Limit Login Attempts

Block IP addresses after 3-5 failed login attempts. Configure automatic lockouts for repeat offenders.

Disable XML-RPC If Not Needed

XML-RPC can be exploited for brute force attacks. If you don't use it for remote publishing or mobile apps, disable it completely.

File Security

Protect wp-config.php

Move wp-config.php above your web root or restrict access via .htaccess. This file contains your database credentials and security keys.

Disable File Editing

Add this line to wp-config.php to disable the theme and plugin editor:

define('DISALLOW_FILE_EDIT', true);

Protect the Uploads Folder

Disable PHP execution in wp-content/uploads/ to prevent uploaded malware from executing. Use .htaccess rules or a security plugin.

Set Correct File Permissions

• Directories: 755
• Files: 644
• wp-config.php: 400 or 440

Updates and Maintenance

Keep Everything Updated

• WordPress core: Enable automatic updates for minor releases
• Plugins: Update within 24-48 hours of release
• Themes: Update as soon as updates are available
• PHP: Use the latest supported version

Remove Unused Themes and Plugins

Delete any themes and plugins you're not actively using. Inactive plugins can still be exploited if they contain vulnerabilities.

Implement Regular Backups

• Schedule automated daily backups
• Store backups off-site (not on the same server)
• Test backup restoration regularly
• Keep multiple backup versions

Monitoring and Detection

Install a Security Plugin

Use a comprehensive security plugin like WP Folder Shield that provides firewall protection, malware scanning, and login security.

Enable File Change Detection

Monitor WordPress core files for unauthorized modifications. Any unexpected changes could indicate a security breach.

Set Up Security Alerts

Configure email or SMS alerts for:

• Failed login attempts
• File changes
• New user registrations
• Plugin installations

Additional Security Measures

Implement Security Headers

Add HTTP security headers to protect against various attacks:

• Content-Security-Policy
• X-Frame-Options
• X-Content-Type-Options
• Referrer-Policy

Hide WordPress Version

Remove WordPress version information from your site's source code to make it harder for attackers to identify vulnerabilities.

Conclusion

Work through this checklist systematically to ensure your WordPress site has comprehensive security coverage. Review and update your security measures quarterly to maintain protection against evolving threats.
