}O.K., Let's take this very simple example:
}
}Let's say that foobar.cc.purdue.edu is one of your so-callled "trusted" 
}systems. One night foobar crashes, or better yet, you announce that on
}Thursday, June 23 at 18:00 you are going to take foobar down for
}an upgrade or maintenance. I sit in my dorm room, or in the MATH dept.
}or any where else on the net with my trusty little cpu of brand X with
}an ethernet card. as soon as I see foobar is down, I bring my little
}box on line as ...........foobar.cc.purdue.edu!!!!!!
}
}Now, tell me how secure your system is.

Very - If I have foobar.cc.purdue.edu connected via a direct line of
some sort. As long as I tell my system to trus foobar ONLY when it is 
soming from a dedicated, hard-wired port, then all is well, and any requests
you make will be rejected.
