Security Headers
same-origin-allow-popups
Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.
camera=(), microphone=(self), geolocation=(), payment=(), usb=(), display-capture=(), fullscreen=(self)
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
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.
DENY
Prevents the page from being embedded in iframes, protecting against clickjacking attacks.
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.
