About Security Headers

Critical Headers

  • Strict-Transport-Security: Forces HTTPS connections
  • Content-Security-Policy: Prevents XSS and injection attacks
  • X-Frame-Options: Prevents clickjacking attacks
  • X-Content-Type-Options: Prevents MIME sniffing

Additional Protection

  • Referrer-Policy: Controls referrer information
  • Permissions-Policy: Controls browser features
  • Cross-Origin-*: CORS and isolation policies
  • X-XSS-Protection: Legacy XSS protection

Implementation Tips

Start with basic headers (HSTS, CSP, X-Frame-Options) and gradually add more. Test thoroughly as some headers may break functionality if misconfigured.
