Hello folks! I am looking for some guidance or direction on how to make sure my "server" locked down as much as possible. I know there are several websites/guides out there but was hoping I could get someone to recommend some good ones to use that cover all the bases solidly.

There are just so much info out there, wading through looking for a solid guide when you ignorant is hazardous.

Server is running Mint and hosts my Plex/Radarr/Sonarr stack. Using a locally hosted reverse proxy for any outside connections.

This started as a project to learn linux, so things are a bit shaky on linux understanding but getting better. I used GPT assistance to lock it down to the best of my ability, making sure (or I think) that most obvious firewalls rules were setup...ect.

Thanks for your help :)

I'm like you, learning as I go along. The answer for complete security seems to be that it takes a bachelors level of learning and you better make a start. I bookmarked this for when I have time to get into it.

For now though, I've just followed the steps in this guide and stopped there. I would recommend this.
