Are you exposing any ports on your home server? (lemmy.world)

Maybe I'm using the wrong terms, but what I'm wondering is if people are running services at home that they've made accessible from the internet. I.e. not open to the public, only so that they can use their own services from anywhere.

I'm paranoid a f when it comes to our home server, and even as a fairly experienced Linux user and programmer I don't trust myself when it comes to computer security. However, it would be very convenient if my wife and I could access our self-hosted services when away from home. Or perhaps even make an album public and share a link with a few friends (e.g. Nextcloud, but I haven't set that up yet).

Currently all our services run in docker containers, with separate user accounts, but I wouldn't trust that to be 100% safe. Is there some kind of idiot proof way to expose one of the services to the internet without risking the integrity of the whole server in case it somehow gets compromised?

How are the rest of you reasoning about security? Renting a VPS for anything exposed? Using some kind of VPN to connect your phones to home network? Would you trust something like Nextcloud over HTTPS to never get hacked?

I've had 22, 80, & 443 open for literal decades. Key auth only on ssh. 80 & 443 rev proxy to inside web services I want to expose only. Also host game servers as needed.

Keep your stuff up to date and follow best practices for securing it. Use things like crowdstrike. If you can segment your network, go ahead.

Unless you have a target on your head your main concern is going to be scripts looking for vulnerabilities.
