hired to lock down an 802.11 network in an office that spanned seven floors.

The first step was to secure the actual network which involved firewalls, VPNs, complicated rules at the router level and, if it had kept going, more stuff that would have made me fall asleep faster than I already was. The second problem, however, was what to do about people bringing in their own wireless hubs and just plugging them in to the network. The solution? The company bought seven Aibo's, each equipped with 802.11 cards, that were left to wander around the offices. Whenever they got within range of an errant wireless hub they were programmed to sit down and start barking.
