So I looked around at a couple of things, and decided to put together a small list of things you can add to your NGINX configuration/server block for enhancing security. I’m going to assume you’re already using an SSL certificate. If you aren’t, start there, and THEN look into how you can improve security 😉   1. Redirect all…
