Step 2: Use Strong, Unique Passwords & Two-Factor Authentication (2FA)

• Passwords: Use complex, unique passwords for all admin, FTP, database, and hosting accounts.
  
• 2FA: Enable two-factor authentication for all user accounts with access to the WordPress admin area. Plugins like Wordfence, Google Authenticator, or Two Factor Authentication can help.

Step 4: Secure Your Login Page

• Change the default login URL (/wp-login.php) to a custom URL using plugins like WPS Hide Login.
  
• Limit login attempts to prevent brute force attacks.
  
• Add CAPTCHA or reCAPTCHA to the login page.
  
• Disable XML-RPC if not needed, or restrict access.

Step 5: Regular Backups

• Always have recent backups stored securely offsite.
  
• Use plugins like UpdraftPlus, BackupBuddy, or managed host backup solutions.
  
• Test your backups by performing restores occasionally.
  

---

Step 6: Use HTTPS/SSL

• Install an SSL certificate (Let’s Encrypt is free and widely used).
  
• Force HTTPS for your entire site.
  
• Google favors HTTPS, and it encrypts data transferred between users and your site.

Step 7: Harden wp-config.php & File Permissions

• If feasible, move wp-config.php to a directory one level above the WordPress root
  
• Set correct file permissions:
  
  • Files: 644
    
  • Directories: 755
    
  • wp-config.php: 600 or 640
    
• Disable file editing from the WordPress admin panel by adding define(‘DISALLOW_FILE_EDIT’, true); to wp-config.php.

Step 8: Monitor Your Site for Malware & Vulnerabilities

• Use security plugins like Wordfence, iThemes Security, or Sucuri Security for malware scans.
  
• Subscribe to security alerts from your hosting provider.
  
• Use uptime monitoring tools to detect site downtime or defacements.

Step 9: Disable Directory Listing

• Prevent users from browsing directories without an index file by adding Options -Indexes to your .htaccess file.
  

---

Step 10: Limit User Roles & Capabilities

• Assign the minimum necessary permissions for each user.
  
• Avoid using Admin role unless necessary.
  
• Regularly review and remove inactive users.

Step 11: Secure Your Database

• Change the default WordPress database prefix (wp_) to something unique during installation.
  
• Use strong database passwords.
  
• Restrict database access to only necessary IPs (via hosting or firewall rules).
  

---

Step 12: Use Security Headers

Add security headers to your site through .htaccess or your server configuration:

• Content-Security-Policy (CSP)
  
• X-Frame-Options
  
• X-Content-Type-Options
  
• Referrer-Policy
  
• Strict-Transport-Security (HSTS)

Bonus Tips

• Disable PHP Execution in directories like /wp-content/uploads/ to prevent malicious scripts.
  
• Use a Content Delivery Network (CDN) to improve security and performance.
  
• Educate your team about phishing, social engineering, and secure practices.
  
• Regularly audit your site security posture.
