I am looking for some recommendations on how to secure the data of my physical servers (against physical theft), that I am about to set up. I am new to selfhosting but have a few years of experience running Linux on a desktop.
My usecase is a simple debian(?) server at home with Paperless ngx and Tailscale for when I am away from home.
The question is how to encrypt the data while still being able to keep the server updated.
Coming from Desktop my first thought was to simply enable FDE on install. But that would mean supplying the password everytime the server needs to reboot for an update. Could someone provide some insights on how often updates to debian require a reboot?
My second thought was to use an encrypted data partition. That way the server could reboot and I could use wireguard to ssh in and open the partition even when I am away from home for a longer time.
I am open to other ideas!
I just bought some PoE hats for my rpis, and have a managed PoE switch; rumor is, this combo basically translates to rPi WoL.
(Not meaning to ignore the rest of your comment, but not in a position to respond fully)
That would be neat.
Like someone else said in here maybe the OP could use a really long cable to a USB drive away from the main server, but I do like the idea of something using hybrid wire(less) to auth.
They could even have a UPS underneath a Pi Zero and, have a PoE HAT too + travel router. Plug in LTE USB with backup SIM card, epoxy all that together and then hide it?
lol, paranoia fixed.
