How do I enable HSTS?

How do I know if HSTS is enabled Linux?
Verify HSTS Header
You can launch Google Chrome Devtools, click into the “Network” tab and look at the headers tab. As you can see below on our Kinsta website the HSTS value: “strict-transport-security: max-age=31536000” is being applied.
