The Growing Threat to WordPress Websites

WordPress powers over 43% of all websites on the internet—making it both incredibly popular and a prime target for hackers. Recent statistics paint a concerning picture:

• 70% of WordPress sites have vulnerabilities that hackers can exploit
• WordPress sites experience 3x more attacks than sites on other platforms
• Small business sites face an average of 300-500 attack attempts weekly
• The average cost of a website breach exceeds $8,000 for small businesses

These numbers highlight why WordPress site security isn’t optional—it’s essential for every website owner, regardless of size.

1. Keep WordPress Core, Themes, and Plugins Updated

Outdated software components represent the single largest security vulnerability for WordPress sites. Each WordPress update includes patches for known security issues—which means delaying updates gives hackers a roadmap to exploit your site.

Why updates are crucial:

• Security patches fix known vulnerabilities
• Performance improvements often include security hardening
• Delayed updates increase your risk exponentially with time

Effective update practices:

• Enable automatic updates for minor WordPress releases
• Create regular backup points before major updates
• Use a staging environment to test updates before applying them live
• Implement a weekly update schedule for all components
• Remove unused themes and plugins completely

Warning signs you need an update protocol:

• You can’t remember the last time you updated WordPress
• You have deactivated plugins still installed
• You’re running WordPress versions from several releases ago

Pro tip: WP Farm’s managed WordPress hosting includes automatic security updates, scheduled backups, and professional update monitoring.

2. Implement Strong Password and Access Policies

Weak authentication remains one of the most exploited security gaps. Brute force attacks—where hackers use automated tools to guess passwords—account for over 80% of successful WordPress breaches.

Password security essentials:

• Require passwords with minimum 12 characters
• Enforce combinations of uppercase, lowercase, numbers, and symbols
• Implement regular password rotation (every 60-90 days)
• Use unique passwords for each user account
• Consider password managers for your team

Access control best practices:

1. Follow the principle of least privilege (users get only the access they need)
2. Remove inactive user accounts immediately
3. Implement two-factor authentication (2FA) for all admin accounts
4. Limit login attempts to prevent brute force attacks
5. Create an IP allowlist for administrative access when possible

Useful security plugins for authentication:

• Wordfence Security
• Sucuri Security
• iThemes Security
• WP 2FA

Strong authentication policies can prevent up to 99.9% of automated attacks against your WordPress site.

3. Secure Your WordPress Database

Your database contains everything valuable in your WordPress site—from user credentials to sensitive customer data. Database security lapses can lead to catastrophic data breaches.

Database security fundamentals:

• Change default database prefix (wp_) during installation
• Implement regular database backups (daily at minimum)
• Restrict database user permissions
• Use encrypted connections to your database
• Run regular security scans for suspicious entries

Database hardening techniques:

1. Place your database on a separate server when possible
2. Disable direct access to database files via .htaccess
3. Remove unnecessary tables and data regularly
4. Implement database activity monitoring
5. Use prepared SQL statements in custom code

Critical warning signs of database vulnerabilities:

• Default table prefix still in use
• phpMyAdmin accessible from public internet
• No encryption for sensitive data
• Missing backup protocol
• Database user has excessive privileges

Database security measures form the backbone of your WordPress site security strategy and should be implemented before launching any site.

4. Install a WordPress Security Plugin

Security plugins provide an all-in-one solution that handles many aspects of WordPress site security automatically. The right plugin can function as your site’s security guard, monitoring for threats 24/7.

What security plugins should provide:

• Regular malware scanning
• Firewall protection
• Login security features
• File integrity monitoring
• Security activity logging
• Blacklist monitoring

Top WordPress security plugins compared:

Implementation tips:

1. Start with the free version to understand features
2. Only install ONE primary security plugin to avoid conflicts
3. Configure scans to run during low-traffic periods
4. Review security reports weekly
5. Keep the security plugin updated religiously

5. Use SSL Encryption (HTTPS)

SSL encryption ensures data transmitted between your website and visitors remains private and secure. Beyond security, Google now uses HTTPS as a ranking signal, making SSL essential for both protection and visibility.

Benefits of SSL implementation:

• Encrypted data transmission prevents man-in-the-middle attacks
• Builds visitor trust with visible security indicators
• Improves SEO rankings
• Required for PCI compliance if accepting payments
• Prevents certain types of content injection attacks

SSL implementation checklist:

1. Obtain an SSL certificate (free via Let’s Encrypt or paid via certificate authorities)
2. Install certificate on your hosting account
3. Update WordPress settings to use HTTPS
4. Implement 301 redirects from HTTP to HTTPS
5. Update internal links to HTTPS
6. Fix mixed content warnings

Common SSL pitfalls to avoid:

• Expired certificates
• Mixed content (HTTP resources on HTTPS pages)
• Incorrect certificate installation
• Wrong domain coverage
• Missing redirects from HTTP to HTTPS

Quality WordPress hosting providers often include free SSL certificates and automatic renewal, saving you time and technical headaches.

6. Harden Your WordPress File Permissions

File permission settings determine who can read, write, and execute files on your server. Incorrect permissions create security vulnerabilities that hackers actively seek out.

Secure file permission settings:

• WordPress core files: 444 (read-only)
• Directories: 755 (owner read/write/execute, group and world read/execute)
• PHP files: 644 (owner read/write, group and world read)
• wp-config.php: 600 (owner read/write only)
• .htaccess: 644 (owner read/write, group and world read)

File security hardening steps:

1. Audit current file permissions
2. Correct permissions using FTP or command line access
3. Move wp-config.php above web root if possible
4. Block access to sensitive files via .htaccess
5. Disable file editing from WordPress admin

Critical files to protect:

• wp-config.php (contains database credentials)
• .htaccess (controls server behavior)
• /wp-content/uploads/ (potential execution point for malicious files)
• Any configuration files with sensitive information

Proper file permissions stop many common attack vectors and should be verified after every major WordPress update.

7. Implement Regular Backups and Recovery Planning

No security measure is 100% foolproof. When prevention fails, recovery becomes your last line of defense—making regular backups absolutely essential for WordPress site security.

Backup strategy essentials:

• Daily automated backups at minimum
• Both database and file system backups
• Off-site storage (different from your hosting server)
• Encrypted backup storage
• Verified restore functionality

Backup implementation options:

1. Host-provided backup services
2. WordPress backup plugins (UpdraftPlus, BackupBuddy, etc.)
3. Manual database exports combined with file backups
4. Third-party backup services (Jetpack Backup, ManageWP, etc.)

Creating a recovery plan:

• Document step-by-step recovery procedures
• Assign responsibility for execution
• Test restore processes quarterly
• Maintain contact information for hosting support
• Set recovery time objectives (how fast you need to be back online)

Security tip: For maximum protection, WP Farm’s security plans include daily off-site backups with 30-day retention and 1-click restoration.

Combining Strategies for Maximum WordPress Security

While each security measure provides protection, maximum security comes from implementing multiple layers of defense. This comprehensive approach creates a security system where if one layer fails, others remain to protect your site.

A complete WordPress site security implementation should include:

1. Regular updates (core, themes, plugins)
2. Strong authentication and access controls
3. Database security measures
4. Professional security plugins
5. SSL encryption
6. Proper file permissions
7. Regular backup and recovery systems

This multi-layered approach provides the highest level of protection against the constantly evolving threat landscape.

Measuring Your WordPress Security

How do you know if your security measures are effective? Regular security assessments help identify gaps in your protection:

Security assessment tools:

• Online WordPress vulnerability scanners
• Security headers check tools
• SSL certificate validators
• Penetration testing services
• Security plugin reports and scores

Aim for quarterly security audits, with additional checks after significant site changes or WordPress updates.
