Ensuring WordPress security requires a layered approach

Ensuring WordPress security requires a layered approach because WordPress is a popular target for hackers.

1. Keep WordPress Updated

• Always use the latest WordPress core version.
• Update themes and plugins regularly.
• Delete unused themes/plugins to reduce attack surface.

2. Use Strong Login Security

• Use strong, unique passwords for all accounts.
• Change the default admin username if it’s admin.
• Limit login attempts to prevent brute-force attacks.
• Enable two-factor authentication (2FA).
• Consider using a password manager for complex passwords.

3. Install a Security Plugin

Popular plugins include:

• Wordfence Security
• iThemes Security
• Sucuri Security

They help with:

• Malware scanning
• Firewall protection
• Login attempt monitoring

4. Protect Your Website with HTTPS

• Install an SSL certificate.
• Ensure all traffic is redirected to HTTPS.
• SSL encrypts data between your server and visitors.

---

5. Secure wp-config.php

• Move wp-config.php outside the public root if possible.
• Set proper file permissions:
  • wp-config.php → 400 or 440
  • Directories → 755
  • Files → 644
• Disable file editing from the dashboard:

define('DISALLOW_FILE_EDIT', true);

---

6. Limit Access and Permissions

• Only give users the permissions they need.
• Avoid using the admin account for everyday tasks.
• Use roles wisely.

---

7. Backup Regularly

• Use automated backup solutions like:
  • UpdraftPlus
  • BackupBuddy
  • Jetpack Backup
• Keep backups offsite (cloud storage, remote server).

---

8. Protect Against Malware & Vulnerabilities

• Disable XML-RPC if not needed (prevents brute-force attacks).
• Install a firewall (plugin-based or server-level like Cloudflare/WAF).
• Scan regularly for malware.

---

9. Monitor Your Site

• Check for suspicious logins.
• Monitor file changes (Wordfence can do this).
• Use server logs to track unusual activity.

---

10. Harden the Server

• Use latest PHP version (WordPress recommends PHP 8.2+).
• Disable directory browsing:

Options -Indexes

• Protect .htaccess:

<Files .htaccess>
Order Allow,Deny
Deny from all
</Files>

• Use a secure hosting provider that handles security patches.

---

11. Other Tips

• Rename the login page (/wp-admin → custom URL) with a plugin.
• Disable PHP execution in uploads folder:

<Files *.php>
deny from all
</Files>

• Regularly review your plugins – remove outdated or poorly rated ones.
