Directive Analysis
Security Headers
accelerometer=(), camera=(), geolocation=(), gyroscope=(), magnetometer=(), microphone=(), payment=*, usb=()
Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.
same-origin
Controls how much referrer information is sent with requests, preventing data leaks to third parties.
max-age=31536000; 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.
SAMEORIGIN, SAMEORIGIN
Prevents the page from being embedded in iframes, protecting against clickjacking attacks.
1; mode=block
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.
