Testing and Validation

Proper testing ensures security headers work as intended:

# Command-line testing with curl
curl -I https://yourdomain.com

# Response headers should include:
Strict-Transport-Security: max-age=31536000
X-Content-Type-Options: nosniff
X-Frame-Options: SAMEORIGIN

Online tools like SecurityHeaders.com and Mozilla Observatory provide comprehensive analysis of your security header implementation, offering grades and specific recommendations for improvement.
