Website security

Headers, transport, and policies that keep visitors safe. Curated from the Website Specification — Security (CC BY 4.0).

Required

  • Serve every page over HTTPS with TLS 1.2 or 1.3; redirect plain HTTP to HTTPS.
  • Send HSTS: Strict-Transport-Security: max-age=...; includeSubDomains.
  • X-Content-Type-Options: nosniff on responses.
  • Clickjacking protection via CSP frame-ancestors (X-Frame-Options as legacy fallback).
  • Cookies are Secure, HttpOnly where possible, with an explicit SameSite; use __Host- / __Secure- prefixes.

Recommended

  • Content Security Policy restricting script, style, image, and frame sources.
  • Referrer-Policy: strict-origin-when-cross-origin.
  • Permissions-Policy to turn off unused powerful features (camera, mic, geolocation).
  • Subresource Integrity (SRI) hashes on third-party scripts and styles.
  • /.well-known/security.txt telling researchers how to report vulnerabilities.
  • DNS CAA records restricting which CAs may issue certificates.

Example headers

Strict-Transport-Security: max-age=63072000; includeSubDomains
X-Content-Type-Options: nosniff
Content-Security-Policy: default-src 'self'; frame-ancestors 'none'
Referrer-Policy: strict-origin-when-cross-origin
