Configure HTTP Strict Transport Security (HSTS) with Apache

This brief tutorial shows students and new users how to configure HTTP Strict Transport Security (HSTS) with Apache on Ubuntu Linux.

If you’re using HTTPS or going to be using it on your websites, then HSTS is something you might want to configure as well.

HTTP Strict Transport Security (HSTS) is a security policy that help protect against downgrade attacks and cookies hijacking. When configured, your web server enforces strict HTTPS connection for web browsers and never via the insecure HTTP protocol.

To enhance connections to your Apache web server make sure that HSTS is also enabled to help protect against man-in-the-middle attack.

Since newer web browsers are all HSTS enabled, this should work across most systems. When a web browser contacts a HSTS enabled server, the browser by default looks for a special HTTP header related to HSTS.
