Inspect raw HTTP headers against 12 OWASP security benchmarks, detect CORS misconfigurations, and generate multi-server configuration snippets.
The Critical Role of Security Headers in Web Defense
HTTP security headers provide a vital layer of defense-in-depth by instructing the client browser to enable built-in security features. Properly configured response headers mitigate cross-site scripting (XSS), clickjacking, SSL stripping, MIME-sniffing, and cross-origin data leakage before application code executes.
Key Security Headers Reference (OWASP Top 10 Alignments)
- Strict-Transport-Security (HSTS): Prevents SSL-stripping and man-in-the-middle attacks by enforcing HTTPS-only browser connections.
- Content-Security-Policy (CSP): Restricts trusted script sources, blocking unauthorized third-party payload injections.
- Permissions-Policy: Controls access to hardware APIs like camera, microphone, geolocation, and payment systems.
- Cross-Origin Isolation (COOP / COEP): Protects process memory against side-channel attack vectors like Spectre and Meltdown.
