Why WordPress Security Matters: Prime Targets for Hackers in 2025

WordPress powers over 43% of all websites online, making it a prime target for hackers. Here’s why attacks continue to increase:

  • WordPress’s open-source nature means vulnerabilities are publicly documented
  • Many site owners neglect regular updates
  • The massive plugin ecosystem creates numerous potential security gaps
  • Automated bots constantly scan for known vulnerabilities

Let’s secure your WordPress site with these proven protection measures.

1. Implement a Web Application Firewall (WAF)

A Web Application Firewall acts as your site’s security guard, filtering out malicious traffic before it reaches your WordPress installation.

Why it’s essential: A good WAF blocks 99.9% of automated attacks, stopping hackers before they even reach your WordPress login page.

Implementation options:

Key features to look for:

  • IP blocking capabilities
  • Country-based restrictions
  • Bot protection
  • Virtual patching for WordPress vulnerabilities

2. Use Strong Authentication Practices

The WordPress login page is the most frequently attacked entry point. Strengthening your authentication is critically important for WordPress security.

Essential authentication measures:

Two-Factor Authentication (2FA)

Require a second verification method beyond just a password. This single step reduces successful breaches by over 99%.

Best 2FA plugins:

Strong Password Enforcement

Require all users to use complex passwords of at least 12 characters.

Password security plugins:

Limited Login Attempts

Block IP addresses after multiple failed login attempts.

Recommended plugins:

3. Keep WordPress Core, Themes, and Plugins Updated

Outdated software is responsible for 56% of all WordPress infections. Updates often include critical security patches.

Best practices for updates:

  • Enable automatic background updates for minor WordPress releases
  • Create a staging environment to test major updates
  • Set a regular schedule for reviewing and updating plugins
  • Remove any plugins or themes that are no longer maintained

Update management tools:

A proactive WordPress security approach always includes a rigorous update schedule.

4. Use a Secure WordPress Hosting Provider

Your hosting provider forms the foundation of your WordPress security posture.

Security features to look for in WordPress hosting:

  • Server-level firewalls
  • Malware scanning and removal
  • Automatic WordPress updates
  • Regular security patching
  • Account isolation (especially on shared hosting)
  • DDoS protection

Most secure WordPress hosting providers:

A robust WordPress security strategy always includes choosing the right host. Learn more about selecting secure WordPress hosting options.

5. Implement Regular Automated Backups

When all else fails, backups ensure you can quickly recover from any security incident.

Backup best practices:

  • Store backups in multiple locations (not just on your server)
  • Encrypt backup files containing sensitive information
  • Test restoration procedures regularly
  • Maintain at least 30 days of daily backups

Reliable backup solutions:

6. Harden Your WordPress Installation

WordPress hardening involves changing default settings and applying additional security measures to reduce your attack surface.

Critical WordPress Security Hardening Steps:

Change Database Prefix

The default “wp_” prefix makes it easier for attackers to target your database tables.

Disable File Editing in the Dashboard

Add this to wp-config.php:

define('DISALLOW_FILE_EDIT', true);

Hide WordPress Version Information

Remove version disclosure, which helps attackers identify vulnerable installations.

Secure wp-config.php

Move this critical file above your web root or add .htaccess protection.

Implement Proper File Permissions

Set correct CHMOD values:

  • Directories: 755
  • Files: 644
  • wp-config.php: 600

7. Use SSL/TLS Encryption (HTTPS)

HTTPS is no longer optional—it’s essential for both security and SEO.

Benefits of SSL/TLS:

  • Encrypts data transmission between servers and browsers
  • Prevents man-in-the-middle attacks
  • Builds visitor trust with the padlock icon
  • Provides an SEO ranking boost

Implementation options:

  • Let’s Encrypt (free certificates)
  • Hosting provider SSL (often included free)
  • Commercial SSL certificates for extended validation

After installation, use Really Simple SSL plugin to ensure proper implementation across your entire site.

WordPress security experts unanimously recommend SSL as a fundamental protection layer.

8. Implement Security Headers

HTTP security headers provide another layer of protection against various attacks.

Essential security headers:

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

Implementation options:

9. Set Up File Integrity Monitoring

When hackers compromise a site, they often modify core WordPress files. File integrity monitoring alerts you when critical files change.

What to monitor:

  • WordPress core files
  • Theme files
  • Plugin files
  • Upload directory for suspicious files

Monitoring solutions:

Implementing file integrity monitoring significantly strengthens your WordPress security posture.

10. Conduct Regular Security Scans

Proactive scanning helps identify vulnerabilities before attackers exploit them.

Types of security scans:

  • Malware detection
  • Vulnerability assessment
  • Blacklist monitoring
  • File change detection

Recommended scanning tools:

11. Protect Against Content Scraping and Hotlinking

Content theft and hotlinking can increase server load and bandwidth costs while harming your SEO efforts.

Protection measures:

  • Disable directory browsing
  • Implement proper hotlink protection
  • Use CAPTCHA for forms
  • Consider content delivery networks (CDNs)

Implementation code for hotlink protection (.htaccess):

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourdomain.com [NC]
RewriteRule \.(jpg|jpeg|png|gif)$ - [NC,F,L]

Content protection is often overlooked in WordPress security planning, but remains essential.

12. Create a Security Response Plan

Even with the best protections, security incidents can still occur. Having a plan reduces damage and recovery time.

Your security response plan should include:

  • Detection procedures
  • Containment strategies
  • Eradication methods
  • Recovery processes
  • Communication templates for affected users
  • Post-incident analysis protocols

Tools to assist with incident response:
