Turning off all unwarranted services is the first line of defense.
Another good point would be to run a firewall, either ipfw or ipf.

A section in the Handbook describes installation and configuration
of ipfw.

You'd want one rule, for sure, for the situation described above.  Something
akin to:

        deny ip from any to me setup

    which should deny any machine from attempting a connection to a server
port on your machine, should any be open.  Put it high in the list.
