HTTP Strict Transport Security

Moving to HSTS

HTTP Strict Transport Security (HSTS)  is a policy mechanism that allows a web server to enforce the use of TLS in a compliant User Agent (UA), such as a web browser. HSTS allows for a more effective implementation of TLS by ensuring all communication takes place over a secure transport layer on the client side. Most notably HSTS mitigates variants of man in the middle (MiTM) attacks where TLS can be stripped out of communications with a server, leaving a user vulnerable to further risk. HSTS has been a highly anticipated and a much needed solution to the problems of HTTP being the default protocol for a UA and the lack of an ability for a host to reliably enforce secure communications. For any site that issues permanent redirects to HTTPS the addition of the HSTS response header is a much safer way of enforcing secure communications for compliant UAs. By preventing the UA from sending even the very first request via HTTP, HSTS removes the only opportunity a MiTM has to gain a foothold in a secure transport layer.   How to enable HSTS? If you have access only to .htaccess then this is the only option (assuming you run Apache, just like Strato…
