The Ultimate WordPress Security Checklist [2025 Update]

WordPress Security Checklist 2025:

In 2025, website security is more critical than ever. WordPress powers over 43% of the web, making it a big target for hackers and malware. If you’re not taking security seriously, your website could be at risk of data breaches, defacement, or even complete loss of access.

Whether you’re a beginner or an experienced developer, this Ultimate WordPress Security Checklist will guide you through essential steps to secure your site in 2025.

🔐 1. Keep WordPress Core Updated

Always update to the latest version of WordPress. Updates often include security patches that protect your site from newly discovered vulnerabilities.

• Enable automatic updates
• Regularly check for core, plugin, and theme updates

🔑 2. Use Strong Admin Credentials

Weak usernames and passwords are the easiest entry point for hackers.

• Avoid using “admin” as username
• Use a strong password with numbers, symbols, and upper/lowercase letters
• Change passwords every 3-6 months

🧱 3. Install a Trusted Security Plugin

Security plugins monitor your site, scan for malware, and block suspicious activity.

Recommended plugins:

• Wordfence
• Sucuri Security
• iThemes Security

📱 4. Enable Two-Factor Authentication (2FA)

2FA adds an extra layer of protection.

• Use apps like Google Authenticator or Authy
• Apply 2FA for all admin and editor users

📥 5. Limit Login Attempts

Prevent brute force attacks by limiting failed login attempts.

• Set a login attempt limit (e.g., 3)
• Block IPs that repeatedly fail to log in

🔒 6. Use SSL (HTTPS) Encryption

SSL encrypts the data exchanged between your site and visitors.

• Get a free SSL from Let’s Encrypt or use your host’s SSL
• Redirect HTTP to HTTPS for all traffic

👥 7. Manage User Roles Carefully

Not every user needs admin access.

• Assign the lowest role necessary
• Regularly review and remove inactive users

🧹 8. Remove Unused Themes & Plugins

Inactive themes and plugins are common entry points for malware.

• Delete all unused plugins and themes
• Only install plugins from trusted sources

📂 9. Backup Your Website Regularly

If your site is hacked, backups can be a lifesaver.

• Use plugins like UpdraftPlus or BlogVault
• Store backups off-site (e.g., Dropbox, Google Drive)

🔧 10. Set Correct File Permissions

Incorrect file permissions can leave your website open to attacks.

• wp-config.php: 400 or 440
• Folders: 755 | Files: 644
• Never allow 777 permissions

🧠 11. Disable XML-RPC

XML-RPC can be exploited for brute force and DDoS attacks.

• Disable it using a plugin or .htaccess rules
• Or use the “Disable XML-RPC” plugin

📊 12. Monitor Activity Logs

Track what happens on your website in real-time.

• Use plugins like WP Activity Log
• Get alerts for any suspicious changes

🛡 13. Use a Web Application Firewall (WAF)

A WAF blocks malicious traffic before it even reaches your site.

• Use WAFs like Cloudflare or Sucuri
• Combine with CDN for speed & security

🧪 14. Scan Your Site for Malware Regularly

Don’t wait until your site is hacked.

• Schedule automatic scans
• Use tools like VirusTotal, Wordfence Scanner, or Sucuri SiteCheck

📉 15. Disable Directory Browsing

If directory browsing is enabled, hackers can see your file structure.

• Add this line to your .htaccess file:

mathematicaCopyEditOptions -Indexes
