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=15552000; preload

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

DENY

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

✓X-XSS-ProtectionPresent

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.
