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

    It’s not fine. Easiest way to rack up utilization on your server is getting hits on all the default service ports. Change that port to any unprivileged port to avoid that somewhat. Not every bot crawler is doing port scans on random non-commercial and unidentified IP space.

    What you’re describing is security through obscurity, but switching from the default port has other benefits like the above.

      Getting “hit” is nothing to worry about by automated scripts. All it does is keep your logs a little bit cleaner. Any attack you should actually worry does not care if your ssh is running on 22 or 7389.
