Hampton is the senior security analyst for the city of Columbus in Ohio. His primary responsibility is to ensure that all physical and logical aspects of the city's computer network are secure from all angles. Bill is an IT technician that works with Hampton in the same IT department. Bill's primary responsibility is to keep PC's and servers up to date and to keep track of all the agency laptops that the company owns and lends out to its employees. After Bill setup a wireless network for the agency, Hampton made sure that everything was secure. He instituted encryption, rotating keys, turned off SSID broadcasting, and enabled MAC filtering. According to agency policy, only company laptops are allowed to use the wireless network, so Hampton entered all the MAC addresses for those laptops into the wireless security utility so that only those laptops should be able to access the wireless network.

Hampton does not keep track of all the laptops, but he is pretty certain that the agency only purchases Dell laptops. Hampton is curious about this because he notices Bill working on a Toshiba laptop one day and saw that he was on the Internet. Instead of jumping to conclusions, Hampton decides to talk to Bill's boss and see if they had purchased a Toshiba laptop instead of the usual Dell.
