Ensure HTTP is redirected to HTTPS

VisokaNivo 1Automatskanginx

Opis

Browsers and clients establish encrypted connections with servers by leveraging HTTPS. Requests leveraging HTTP are unencrypted. Unencrypted requests should be redirected so they are encrypted. Any listening HTTP port on your web server should redirect to a server profile that uses encryption. The default HTTP (unencrypted) port is 80. Every server block listening on plain port 80 must redirect with return 301/302/307/308 https://... or a rewrite to https:// (catch-all blocks may instead return a 4xx/444 code), and at least one TLS listener must exist. Evaluated on the merged configuration printed by `nginx -T` (all included files; needs permission to read them). CIS marks this recommendation Manual; the automated check implements its audit procedure.

Očekivani izlaz: compliant

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

In each port-80 server block use 'return 301 https://$host$request_uri;'. Then run nginx -t and reload nginx.
