What are security headers?
HTTP security headers configure browser behavior to reduce risk from XSS, clickjacking, mixed content, and cross-origin leaks.
How to fix common issues
- Set X-Content-Type-Options: nosniff
- Adopt a strict CSP with nonces/hashes
- Enable HSTS with preload readiness
What this test checks
- CSP directive configuration and syntax validation
- Detection of unsafe-inline and unsafe-eval usage
- Nonce and hash implementation guidance
- Frame-ancestors directive for clickjacking protection
- X-Frame-Options header presence and configuration
- CSP frame-ancestors directive validation
- Frame embedding restrictions and policy consistency
- X-Content-Type-Options: nosniff implementation
- MIME type sniffing protection validation
- Content-Type header configuration
- Referrer-Policy header configuration
- Cross-origin referrer information control
- Privacy-preserving referrer policies
- Permissions-Policy header validation
- Browser API access restrictions (camera, geolocation, etc.)
- Feature policy best practices compliance
- Cross-Origin-Embedder-Policy (COEP) configuration
- Cross-Origin-Opener-Policy (COOP) validation
- Cross-Origin-Resource-Policy (CORP) settings
- Server header exposure and version disclosure
- X-Powered-By header detection
- Technology stack information leakage
- HTTP Strict Transport Security (HSTS) configuration
- HSTS preload readiness validation
- HTTPS enforcement policies
