I just setup a minecraft server on an old laptop, but to make it acessible i needed to open up a port. Currently, these are the ufw rules i have. when my friends want to connect, i will have them find their public ip and ill whilelist only them. is this secure enough? thanks

`Status: active

To Action From

22/tcp ALLOW Anywhere Anywhere ALLOW my.pcs.local.ip`

also, minecraft is installed under a separate user, without root privlege

      Normal for who? I wouldn’t expose SSH on 22 to the internet unless you have someone whose full time job is monitoring it for security and keeping it up to date. There are a whole lotta downsides and virtually no upsides given that more secure alternatives have almost zero overhead.

        Shodan reports that 35,780,216 hosts have SSH exposed to the internet.

        Moving SSH to ports other than 22 is not security. The bots trying port 22 on random addresses with random passwords don’t have a chance of getting in unless you’re using password authentication with weak passwords or your SSH is very old.

        SSH security updates are very infrequent and it takes practically no effort to keep SSH up to date. If you’re using a stable distribution, just enable automatic security updates.

          Moving to another port isn’t a bad idea though. It gives you cleaner logs which is nice.

        I had it open for a web server for 2.5 years because I was lazy and my IP changed a lot and I traveled and didn’t have a VPN setup and never had any issues as far as I could tell. Disabled password and root auth but was also fine with wiping that server if there were issues. It’s certainly not recommended but isn’t immediately always going to be an issue

          ssh is one of the most secure servers you can run. The tailscale propaganda is crazy in this community.

      If you have ssh open to the world then it’s better to disable root logins entirely and also disable passwords, relying on ssh keys instead.

        Don’t use passwords for public SSH in the first place. Disable password authentication and use pubkeys.

          And disable ssh to root. Hell, just disable root login altogether and use sudo.

      For public facing only use key based authentication. Passwords have too much risk associated for public facing ssh
