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 :)

If you really need to expose something to the internet set yourself up an SSO/OIDC provider and have it sit in front of the service and have a deny-first policy in place, whitelist the known few IP’s that need to connect regularly or alternatively geoblock.

Also suggest setting up some security headers, however headers can be confusing for beginners.
