How to Effectively Secure Your WordPress Site with Wordfence and Other Measures

WordPress security is critical for protecting your business assets, customer data, and brand reputation. With WordPress powering over 40% of websites globally, it’s a prime target for cybercriminals. This comprehensive guide covers essential security measures every WordPress site owner should implement and demonstrates how Wordfence provides enterprise-level protection.

1. Implement Comprehensive Backup Strategies

Your first line of defense is a reliable backup system. Before any updates or changes, ensure you have current backups stored in multiple locations. Professional solutions include:

• UpdraftPlus for automated cloud backups
• Hosting-level backups from premium providers
• Incremental backup systems for large sites

Best practice: Schedule daily backups with 30-day retention for critical business sites.

2. Fortify Login Pages and Admin Areas

Change Default Login URLs

Attackers routinely scan standard WordPress login pages (/wp-admin/ and /wp-login.php). Implement these countermeasures:

• Use WPS Hide Login or Change wp-admin login plugins to customize login URLs
• Create unique, non-obvious login paths
• Document changes securely for your team

Restrict Admin Directory Access

Limit wp-admin access to authorized IP addresses via .htaccess:

Order Allow,Deny
Deny from all
Allow from XX.XX.XXX.XXX

3. Maintain Updated Software

Outdated WordPress core, plugins, and themes represent 90% of successful breaches. Implement these protocols:

• Enable automatic security updates
• Schedule weekly manual reviews
• Remove unused plugins and themes
• Test updates in staging environments first

4. Eliminate Default Usernames

Never use “admin” as your administrator username. Instead:

1. Create a new administrator account with a unique username
2. Transfer all content ownership
3. Delete the default admin account
4. Use strong, role-specific usernames

Daily Attack Reality: Automated bots attempt thousands of login attempts using default credentials. Here’s a sample Wordfence report showing blocked intrusion attempts:

5. Database Security Best Practices

Customize Table Prefixes

During installation, replace the default wp_ prefix with a unique identifier to prevent SQL injection attacks.

Restrict Database Access

• Limit database connections to localhost only
• Use strong, unique database passwords
• Implement SSL connections for remote access

Password Management

Never use browser-saved passwords for administrative access. Implement password managers and enforce manual entry for critical systems.

6. Configure Proper File Permissions

Set secure Unix permissions:

• Files: 640 or 644
• Directories: 750 or 755
• wp-config.php: 600
• Never use 777 permissions

7. Protect wp-config.php

This file contains your database credentials. Add this to .htaccess:

<files wp-config.php>
Order deny,allow
Deny from all
</files>

8. Implement Login Attempt Restrictions

Use Limit Login Attempts Reloaded or Wordfence to:

• Limit failed login attempts to 3-5
• Implement progressive lockout periods
• Block IPs after repeated failures

9. Deploy Two-Factor Authentication (2FA)

Mandatory for all administrative accounts. Options include:

• Wordfence 2FA (integrated solution)
• WP 2FA (standalone plugin)
• Google Authenticator integration

10. Hide WordPress Version Information

Prevent version-specific exploits by adding to functions.php:

remove_action('wp_head','wp_generator');
