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 :)

Thanks for sharing! This was essentially my experience growing up, I am old now and never bounced back fully in math either.
I was the oldest of 8, so much of my time was helping my siblings with schoolwork on top of my own “self learning” Problem is most of our family is nerodivergent, undiagnosed until adulthood… So you know none of us got the help we needed either. Another flaw in homeschooling as you dont have people trained to pick up dyslexia early, so kids struggle too much.
Your comment helped me feel that someone out there understands, thanks! :)
