Hello peoples,
I am looking for tips on how to make my self-hosted setup as safe as possible.
Some background: I started self-hosting some services about a year ago, using an old lenovo thin client. It’s plenty powerful for what I’m asking it to do, and it’s not too loud. Hardware wise I am not expecting to change things up any time soon.
I am not expecting anyone to take the time to baby me through the process, I will be more than happy with some links to good articles and the like. My main problem is that there’s so much information out there, I just don’t know where to start or what to trust.
Anyways, thank you for reading.

One “hammer” mitigation to most threats could conceivably face when self-hosting is to never expose your services to the internet using a firewall. “Securing” your services against a small circle of guests/friends/family members in your home network is a lot simpler than securing against the entire world.
If you need to access your services remotely, there are ways to achieve that without permanently opening a single port to the internet such as Tailscale or ZeroTier.Otherwise, commonly used tools in self-hosting such as Docker or VMs usually offer quite decent separation even if a service is compromised.
Nothing replaces good security hygiene though. Keep your stuff up-to-date. Use secure methods of authentication such as hard to guess passwords or better. Make frequent backups (3-2-1). The usual.
