Saw a post on Slashdot that I though was worth repeating here regarding network security in office spaces:
top secret computers connected in a network configuration aren’t connected to the outside. the networks i’ve seen aren’t even connected to anything outside the very room these computers are kept.
in fact, each computer’s network cable (bright blue) goes up the wall, to about 2 feet from the ceiling, then wraps around to a switch, also located near the ceiling.
the purpose of this is so one can immediately observe every network connected device by looking along the wall. this would prevent anyone from connecting an unauthorized system into the network.
