Security Headers

✗Strict-Transport-SecurityMissing

Forces browsers to use HTTPS for all future requests, preventing man-in-the-middle attacks and SSL stripping.

How to add it:

nginx

add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

apache

Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"

cloudflare

SSL/TLS > Edge Certificates > Enable HSTS (toggle on, set max-age to 12 months, enable includeSubDomains)

✗X-Content-Type-OptionsMissing

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

How to add it:

nginx

add_header X-Content-Type-Options "nosniff" always;

apache

Header always set X-Content-Type-Options "nosniff"

cloudflare

Rules > Transform Rules > Managed Transforms > Enable "Add X-Content-Type-Options header"

✗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-ProtectionMissing

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

How to add it:

nginx

add_header X-XSS-Protection "0" always;

apache

Header always set X-XSS-Protection "0"

cloudflare

Rules > Transform Rules > HTTP Response Header Modification > Set X-XSS-Protection to "0"

Security headers protect the browser. OSN maps what's exposed underneath — servers, open ports, known CVEs, DNS and WHOIS.
