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 open 443 and 80 on my router and forward it to a reverse proxy.

I have a couple of service that are exposed but most of them make sense only when I'm home so I whitelist private IP address on my reverse proxy.

If you do.your basic security such as updating your servers and services and not having dumb password, you shouldn't be afraid. Think about it, all of the services that you use is exposed on the internet. I did work for big company and they don't do much more than what you would probably do, except maybe having some automated monitoring that flag weird stuff. But hey, aside from bots, I don't think Russian hackers are interested in your stuff. Stay low profile with your exposed things and it's gonna be alright. Make sure you backup.
