20 Proven Ways to Secure Your WordPress Site from Hackers in 2024

When it comes to running a WordPress website, security should be your top priority. Hackers are always on the lookout for vulnerabilities, but with a few simple steps, you can make your site virtually impenetrable. In this guide, we’ll explore 20 proven methods to secure your WordPress website. Whether you're a beginner or an experienced site owner, these tips will help protect your website and give you peace of mind.

1. Keep WordPress Updated

• Why: WordPress updates often include patches for security vulnerabilities. Using outdated versions makes your site an easy target for hackers.
• How:
  1. Log in to your WordPress dashboard.
  2. Go to Dashboard > Updates and check for available updates.
  3. Enable automatic updates for minor updates in wp-config.php by adding:   define('WP_AUTO_UPDATE_CORE', true);

2. Use Strong Passwords

• Why: Weak passwords are easily cracked through brute force attacks. A strong password protects your admin account and database.
• How:
  1. Use a combination of uppercase, lowercase, numbers, and symbols.
  2. Tools like LastPass or Dashlane can generate and store secure passwords.

3. Enable Two-Factor Authentication (2FA)

• Why: Adds an extra layer of security. Even if your password is stolen, hackers can’t log in without the second factor.
• How:
  1. Install the plugin Google Authenticator – Two Factor Authentication.
  2. Follow the setup process to sync with an authentication app like Google Authenticator.

4. Limit Login Attempts

• Why: Prevents brute force attacks by restricting the number of failed login attempts.
• How:
  1. Install the Limit Login Attempts Reloaded plugin.
  2. Set limits for failed logins under Settings > Limit Login Attempts.

5. Hide Your Login Page

• Why: The default login URLs (/wp-login.php and /wp-admin) are well-known targets for attackers.
• How:
  1. Use the plugin WPS Hide Login to change the login URL to something custom like /secure-login.

6. Secure Your wp-config.php File

• Why: This file contains your database credentials and other sensitive data. Securing it prevents unauthorized access.
• How:
  1. Move wp-config.php to a non-public directory.
  2. Update its permissions using: chmod 400 wp-config.php

7. Install a Security Plugin

• Why: A security plugin automates scanning, malware removal, and real-time monitoring.
• How:
  1. Install plugins like Wordfence, Sucuri Security, or iThemes Security.
  2. Enable features such as malware scans and IP blocking in their settings.

8. Use HTTPS

• Why: HTTPS encrypts data transfer between your website and users, securing sensitive information.
• How:
  1. Get a free SSL certificate from Let’s Encrypt (offered by most hosting providers).
  2. Install the Really Simple SSL plugin to enable HTTPS across your site.

9. Regularly Backup Your Site

• Why: A backup ensures you can restore your site in case of a hack or server crash.
• How:
  1. Use plugins like UpdraftPlus to schedule automatic backups.
  2. Store backups offsite (e.g., Google Drive or Dropbox).

10. Disable File Editing

• Why: The built-in editor in WordPress can be exploited by hackers to insert malicious code.
• How:
  1. Add the following to your wp-config.php file: define('DISALLOW_FILE_EDIT', true);

11. Protect Against DDoS Attacks

• Why: DDoS attacks overwhelm your server, making your site unavailable to visitors.
• How:
  1. Use a Web Application Firewall (WAF) like Cloudflare.
  2. Configure it to block excessive requests from specific IPs.

12. Strengthen Your Database

• Why: Default database prefixes (like wp_) are common targets for SQL injection attacks.
• How:
  1. During installation, set a custom prefix (e.g., secure_).
  2. Change an existing prefix using plugins like Change Table Prefix.

13. Monitor Admin Activity

• Why: Tracking user actions helps detect suspicious activity early.
• How:
  1. Install the Activity Log plugin.
  2. Check logs regularly for changes to files, settings, and accounts.

14. Disable XML-RPC

• Why: XML-RPC is a common entry point for DDoS and brute force attacks.
• How:
  1. Add this code to your .htaccess file: <Files xmlrpc.php> Order Deny,Allow Deny from all </Files>
  2. Alternatively, use the Disable XML-RPC plugin.

15. Choose Secure Hosting

• Why: Secure hosting provides a strong foundation for site security.
• How:
  1. Opt for hosts like SiteGround, WP Engine, or Kinsta that include features like malware protection and backups.

16. Scan Your Website Regularly

• Why: Regular scans detect vulnerabilities and malware.
• How:
  1. Use plugins like MalCare or Wordfence to schedule automatic scans.
  2. Review the scan results for any flagged issues.

17. Set Correct File Permissions

• Why: Loose file permissions allow hackers to overwrite files.
• How:
  1. Set the following permissions via your FTP client or hosting control panel:
     • Files: 644
     • Directories: 755
     • wp-config.php: 400

18. Use Strong Firewall Rules

• Why: A firewall blocks malicious traffic before it reaches your site.
• How:
  1. Configure a WAF using Cloudflare or Sucuri.
  2. For advanced control, manually define rules in .htaccess.

19. Protect Against Hotlinking

• Why: Prevents other sites from embedding your images and consuming your bandwidth.
• How:
  1. Add the following to .htaccess: 

     RewriteEngine on
     RewriteCond %{HTTP_REFERER} !^$
     RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourwebsite.com [NC]
     RewriteRule \.(jpg|jpeg|png|gif)$ - [F,NC,L]

20. Educate Your Team

• Why: Human errors, like falling for phishing scams, can compromise security.
• How:
  1. Conduct regular training sessions on identifying threats.
  2. Share best practices, like avoiding public Wi-Fi when accessing the site.
