The Homelab Show frequently explores the topic of security in a homelab. I’m a big fan of Jay LaCroix, since I learned how to use Proxmox from his fabulous Proxmox course. They touch on security from the broad to the specific, and talk about incidents, as well. You do have to search through it to find the episodes where security is a topic, but they are there.
Sweet, thanks for the tip. I also have learned a lot of Linux basics from Jay through LearnLinux TV. Good educator. Did not know about The Homelab Show though, so I will definitely check that out.
