Not really true. Just use this analogy to show him: You computer is like a house. Opening a well secured port is like leaving a door on the outside of the house unlocked, but that door only access one room with no other doors of valuables.
Opening a port doesn't make your computer vulnerable unless the service running on it (in this case, Deus Ex) is vulnerable because of poor coding.

Also not really true. It's very easy to hack, as long as the server you're hacking is running a vulnerable program, and almost ALL programs are vulnerable at some level if you look hard enough. The reason that people aren't getting hacked left and right isn't because it's hard to do per se, it's just that it takes a while to do it.
Now then, you only really have to worry if Deus Ex is vulnerable.
