Introduction

Websites are frequent targets of cyberattacks, making security a top priority. A Next.js frontend with a WordPress backend provides more control over vulnerabilities while maintaining content flexibility.

Common Threats in WordPress and Next.js

  • Brute force attacks – Hackers try multiple login combinations
  • SQL injection – Exploits database vulnerabilities
  • Cross-site scripting (XSS) – Injects malicious scripts into web pages

Best Security Practices

Strengthen Authentication

  • Enable two-factor authentication (2FA) for WordPress logins
  • Limit login attempts to prevent brute force attacks
  • Restrict admin access by IP

Secure API Requests

  • Use JWT authentication for Next.js API calls
  • Restrict API access to verified clients
  • Implement rate limiting to prevent abuse

Keep Software Updated

  • Regularly update WordPress core, themes, and plugins
  • Remove unused plugins to minimize vulnerabilities
  • Use security plugins like Wordfence or Sucuri

Enable HTTPS & Secure Hosting

  • Install SSL certificates to encrypt traffic
  • Use a WAF (Web Application Firewall) for additional security
  • Regularly back up website data
