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-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

strict-origin

Controls how much referrer information is sent with requests, preventing data leaks to third parties.

✓Strict-Transport-SecurityPresent

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

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

✓X-Frame-OptionsPresent

sameorigin

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

✓X-XSS-ProtectionPresent

1; mode=block

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