Security Headers

✓Cross-Origin-Opener-PolicyPresent

unsafe-none

Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.

✓Permissions-PolicyPresent

camera=(), microphone=(), geolocation=()

Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.

✓Referrer-PolicyPresent

strict-origin-when-cross-origin

Controls how much referrer information is sent with requests, preventing data leaks to third parties.

✓Strict-Transport-SecurityPresent

max-age=31536000

Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.

✓X-Content-Type-OptionsPresent

nosniff

Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.

✓X-Frame-OptionsPresent

sameorigin

Prevents the page from being embedded in iframes, protecting against clickjacking attacks.

—X-XSS-ProtectionDeprecated

Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.

Recommendations

→Add base-uri directive with appropriate restrictions
→Add connect-src directive with appropriate restrictions
→Add form-action directive with appropriate restrictions
→Consider implementing a stricter Content Security Policy

Beyond headers: infrastructure exposure

via OSN, our sister project

Security headers protect the browser. OSN maps what's exposed underneath — servers, open ports, known CVEs, DNS and WHOIS.
