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-PolicyPresent
no-referrer-when-downgrade
Controls how much referrer information is sent with requests, preventing data leaks to third parties.
✓Strict-Transport-SecurityPresent
max-age=31536000; includeSubdomains; 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
0
Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.
1 recommended security header is missing on cdm.ee.
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.
