Security Headers
Isolates the browsing context to prevent Spectre-type side-channel attacks and cross-origin window manipulation.
How to add it:
add_header Cross-Origin-Opener-Policy "same-origin" always;Header always set Cross-Origin-Opener-Policy "same-origin"Rules > Transform Rules > HTTP Response Header Modification > Set Cross-Origin-Opener-Policy to "same-origin"Restricts which browser features (camera, microphone, geolocation) the page can use, limiting attack surface.
How to add it:
add_header Permissions-Policy "camera=(), microphone=(), geolocation=()" always;Header always set Permissions-Policy "camera=(), microphone=(), geolocation=()"Rules > Transform Rules > HTTP Response Header Modification > Set Permissions-Policy valueControls how much referrer information is sent with requests, preventing data leaks to third parties.
How to add it:
add_header Referrer-Policy "strict-origin-when-cross-origin" always;Header always set Referrer-Policy "strict-origin-when-cross-origin"Rules > Transform Rules > HTTP Response Header Modification > Set Referrer-Policy to "strict-origin-when-cross-origin"max-age=31536000
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"1; mode=block
Legacy XSS filter for older browsers. Modern browsers use CSP instead. Set to "0" to avoid false positives.
