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.
