WordPress Website Security Best Practices

WordPress is the most popular content management system (CMS) in the world, powering over 40% of websites on the internet. However, its popularity makes it a prime target for hackers, malware, and other security threats. If you own a WordPress website, securing it should be your top priority to protect your data, users, and online reputation.

In this blog, we will discuss the best practices to enhance WordPress security and prevent cyber threats.

1. Keep WordPress Core, Themes, and Plugins Updated

WordPress frequently releases updates to patch vulnerabilities and enhance security. Keeping your WordPress core, themes, and plugins updated ensures that your site remains protected from known security issues.

Best Practices:

Enable automatic updates for minor WordPress core updates.
Regularly check and update plugins and themes.
Remove unused plugins and themes to reduce security risks.

2. Use Strong Usernames and Passwords

Weak passwords and common usernames like “admin” make it easy for hackers to gain unauthorized access to your website.

Best Practices:

Avoid using “admin” as the username.
Create strong passwords with a mix of uppercase, lowercase, numbers, and symbols.
Use a password manager to store and manage passwords securely.

3. Implement Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) adds an extra layer of security by requiring a second form of verification in addition to a password.

Best Practices:

Use a 2FA plugin like Google Authenticator or Wordfence.
Require 2FA for all admin and editor accounts.
Use time-sensitive codes instead of SMS-based authentication for better security.

4. Install a Security Plugin

Security plugins help monitor and protect your WordPress website from threats and vulnerabilities.

Recommended Security Plugins:

Wordfence Security – Provides firewall protection, malware scanning, and login security.
Sucuri Security – Offers website monitoring, malware scanning, and security hardening.
iThemes Security – Helps prevent brute-force attacks and secures user authentication.

5. Use a Web Application Firewall (WAF)

A Web Application Firewall (WAF) helps block malicious traffic before it reaches your website.

Best Practices:

Use a cloud-based WAF service like Cloudflare or Sucuri.
Enable security rules to prevent common attacks such as SQL injection and cross-site scripting (XSS).

6. Secure Your Login Page

Hackers often use brute-force attacks to gain access to your website’s login page.

Best Practices:

Change the default login URL from /wp-admin to a custom URL.
Limit the number of login attempts with a plugin like Limit Login Attempts Reloaded.
Restrict login access by IP address using .htaccess rules.

7. Regularly Backup Your Website

Regular backups ensure that you can restore your website in case of a security breach or data loss.

Best Practices:

Use backup plugins like UpdraftPlus, VaultPress, or BackupBuddy.
Store backups on external locations such as Google Drive, Dropbox, or Amazon S3.
Automate backups on a daily or weekly basis.

8. Use Secure Hosting

A reliable and secure hosting provider is the foundation of WordPress security.

Best Practices:

Choose a hosting provider with built-in security features like SSL, DDoS protection, and automated backups.
Opt for Managed WordPress Hosting (e.g., Kinsta, WP Engine) for added security benefits.
Enable server-side security measures such as malware scanning and intrusion detection.

9. Use SSL Certificates for HTTPS Encryption

SSL (Secure Sockets Layer) encrypts data transferred between your website and users, ensuring secure communication.

Best Practices:

Install an SSL certificate from Let’s Encrypt (free) or a premium provider.
Enable HTTPS across the entire website.
Ensure all internal links and resources are loaded over HTTPS.

10. Disable XML-RPC

XML-RPC can be exploited by hackers to perform brute-force attacks and DDoS attacks.

Best Practices:

Disable XML-RPC using a plugin like Disable XML-RPC.
Alternatively, disable XML-RPC manually by adding the following code to .htaccess:
```
<Files xmlrpc.php>
Order Deny,Allow
Deny from all
</Files>
```

11. Set Proper File and Folder Permissions

Incorrect file permissions can allow unauthorized users to modify critical website files.

Best Practices:

Set wp-config.php file permissions to 600.
Set other WordPress files to 644 and folders to 755.
Use an FTP client or command line to update file permissions securely.

12. Monitor User Activity and Audit Logs

Tracking user activity helps detect suspicious behavior and unauthorized access.

Best Practices:

Use plugins like WP Security Audit Log to monitor user activities.
Regularly review login logs and failed login attempts.

13. Protect Against SQL Injection and Cross-Site Scripting (XSS)

SQL injection and XSS attacks can compromise your website’s database and expose sensitive data.

Best Practices:

Use a security plugin with firewall protection.
Keep WordPress and plugins updated.
Sanitize and validate user input fields to prevent malicious code execution.

14. Hide WordPress Version

Displaying the WordPress version number can give hackers information about potential vulnerabilities.

Best Practices:

Remove WordPress version information from your site’s header by adding the following code to functions.php:
```
function remove_wp_version() {
    return '';
}
add_filter('the_generator', 'remove_wp_version');
```

15. Regular Security Scans and Malware Removal

Regular security scans help identify vulnerabilities and malware infections before they cause damage.

Best Practices:

Use security scanning plugins like MalCare, Wordfence, or Sucuri.
Perform manual security checks periodically.

Conclusion

WordPress security is an ongoing process that requires regular monitoring, updates, and proactive measures. By implementing the best practices mentioned above, you can significantly reduce the risk of cyber threats and ensure your website remains safe and secure.

By following these security measures, you can protect your WordPress website from potential threats and ensure a safe experience for your visitors. Start securing your site today!
