Should I be concerned with exposing my server to the public? (lemmy.world)

Hey all! For the longest time I've had a server that hosts some things (eg Syncthing), but is only available via SSH tunneling.

I've been thinking of self-hosting more things like Nextcloud and Vaultwarden. I can keep my SSH tunneling setup but it might make it difficult to do SSL.

How do you manage the security of having public-facing servers?

I would add to this, disable icmp response on any internet facing server that does not aboluetly require it, it make it whitelisted to your know IPs when it is. If your server does not appear online then you will only really be vulernable to targeted attacks where your ip is already known.
