I heard that hosting a minecraft server (public) is super super secure. Like, you'd need a government hacker to hack into it (I'm not talking about client-hacking) to gain access to your system.
In order for other players to play on your server, you have to give others your public IP. Many times I've heard that that is a big no-no. I would really like to host a minecraft server but I'm currently in a network of other computers that shouldn't be tampered with (or, hacked in to from the minecraft server). How would I be able to highly prevent, or completely stop someone gaining access to my system or a network of systems?
I can accept that if there is no solution is the answer, than that's okay as well. I am currently using a macintosh computer.
