HSTS
Stands forHTTP Strict Transport Security
CategoriesTechnology & Computing

HSTS stands for HTTP Strict Transport Security, a cybersecurity abbreviation.

A response header that tells browsers to connect to a site only over HTTPS for a set period, automatically upgrading http links and refusing to let users click through certificate errors. It defeats SSL-stripping attacks on public Wi-Fi.

Example: Enable HSTS with a one-year max-age once every subdomain is served over HTTPS.

Usage notes

Standardized in RFC 6797 (2012). Sites can join the HSTS preload list built into major browsers so that even the very first visit uses HTTPS, and whole top-level domains such as .app and .dev are preloaded. Turning it on before all subdomains have certificates can lock users out of them.
