Security Headers

✗Permissions-PolicyMissing

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

How to add it:

nginx
add_header Permissions-Policy "camera=(), microphone=(), geolocation=()" always;
apache
Header always set Permissions-Policy "camera=(), microphone=(), geolocation=()"
cloudflare
Rules > Transform Rules > HTTP Response Header Modification > Set Permissions-Policy value
✗Referrer-PolicyMissing

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

How to add it:

nginx
add_header Referrer-Policy "strict-origin-when-cross-origin" always;
apache
Header always set Referrer-Policy "strict-origin-when-cross-origin"
cloudflare
Rules > Transform Rules > HTTP Response Header Modification > Set Referrer-Policy to "strict-origin-when-cross-origin"
✓Strict-Transport-SecurityPresent

max-age=31536000; includeSubDomains

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-ProtectionPresent

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 project

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