Security Headers

✗Cross-Origin-Opener-PolicyMissing

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

How to add it:

nginx

add_header Cross-Origin-Opener-Policy "same-origin" always;

apache

Header always set Cross-Origin-Opener-Policy "same-origin"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set Cross-Origin-Opener-Policy to "same-origin"

✓Permissions-PolicyPresent

geolocation=none; camera='self'; microphone=none; fullscreen='self'; clipboard='self',geolocation=none; camera='self'; microphone=none; fullscreen='self'; clipboard='self'

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

✓Referrer-PolicyPresent

strict-origin-when-cross-origin,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; includeSubDomains,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,nosniff

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

✗X-Frame-OptionsMissing

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

How to add it:

nginx

add_header X-Frame-Options "DENY" always;

apache

Header always set X-Frame-Options "DENY"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set X-Frame-Options to "DENY"

✓X-XSS-ProtectionPresent

1; mode=block

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

2 recommended security headers are missing on epodatelna-test.nn.sk.

Recommendations

→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.
