Directive Analysis
Security Headers
unsafe-none
Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.
accelerometer=(), autoplay=(), camera=(), cross-origin-isolated=(), display-capture=(self), encrypted-media=(), fullscreen=*, geolocation=(self), gyroscope=(), keyboard-map=(), magnetometer=(), microphone=(), midi=(), payment=*, picture-in-picture=*, publickey-credentials-get=(), screen-wake-lock=(), sync-xhr=*, usb=(), xr-spatial-tracking=(), gamepad=(), serial=()
Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.
strict-origin-when-cross-origin
Controls how much referrer information is sent with requests, preventing data leaks to third parties.
max-age=63072000; includeSubDomains; preload
Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.
nosniff
Prevents browsers from MIME-sniffing responses away from the declared Content-Type, blocking drive-by downloads.
Prevents the page from being embedded in iframes, protecting against clickjacking attacks.
How to add it:
add_header X-Frame-Options "DENY" always;Header always set X-Frame-Options "DENY"Rules > Transform Rules > HTTP Response Header Modification > Set X-Frame-Options to "DENY"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 hallerup.net.

Recommendations
- →Consider implementing a stricter Content Security Policy
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.
