Extremely difficult, and in many cases quite unnecessary. No, you let
them on the network, and then make sure that won't hurt you more than
you're prepared to accept. For instance, someone could join my wifi
network - all they need is the WPA2 PSK, which is well known around
the place - and use/abuse our internet connection; but they couldn't
access my PostgreSQL databases, because the firewall doesn't permit
access to port 5432.
