To the information security professional wireless networking may be thought of as a four letter word to be avoided at all costs. Regardless of the security implication wireless networking can provide cost efficiency, and because of that wireless technologies are here to stay.
A wireless network does not use cables, but instead uses radio waves. Such networks enhance the functionality of computing devices by freeing them from the location constraints of a wired network. Although wireless networking is of great use to the laptop users who move from one location to the other throughout the day, there are benefits for fixed users as well. Many schools and businesses have an architecture that is unsuited for a wired network.
