Directive Analysis
Security Headers
same-origin
Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.
camera=(), microphone=(), geolocation=()
Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.
strict-origin-when-cross-origin
Controls how much referrer information is sent with requests, preventing data leaks to third parties.
max-age=63072000; includeSubDomains; preload
Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.
nosniff
Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.
SAMEORIGIN
Prevents the page from being embedded in iframes, protecting against clickjacking attacks.
0
Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.
Beyond headers: infrastructure exposure
via OSN, our sister projectSecurity headers protect the browser. OSN maps what's exposed underneath — servers, open ports, known CVEs, DNS and WHOIS.
