What actual damage do you secure your servers against? Whats the attack vector? (lemmy.ca)

I'm a software developer working in the telecam sector on security related products, so I know a fair bit about system security. Yet I wound secure my own system far less than most people here if I didn't enjoy cybersecurity as a hobby.

I wonder what you are securing against? Some examples:

jellyfin: unless you have home videos on there, what does it matter if someone exfiltrates some movies? Surely you have basic DOS protection and/or region locking to reduce wasted network traffic, right?
linux: I assume nobody is using their servers as daily drive PCs, so what does it matter if somehow your system is superficially compromised. You can always reimage. Sure they could mine some bitcoin with your system, but it doesn't have that much PSU headroom to cost you much on your bills, right?

It just seems like most attack vectors lead to mild annoyance at most for most systems.

Do you guys just enjoy cybersecurity? Do you actually keep sensitive data on your self hosted systems? Do you self-host on expensive hardware? What am I missing?

From my perspective, self hosting is a hobby, we run services we feel we need, but it's also something we do for fun. As such some people enjoy thinking about and deploying the most secure server possible, regardless of actual threats. However, to directly answer your question, yes there isn't really a lot that can be stolen from a self host residential server, maybe if you hack a valutwarden instance and acquire all the credit card details stored in it and all the id's stored in it. But the main hack isnt stealing, but deploying a bot net of some sort.
