Wireless stations, the 802.11 terminology for client computers, are crucial to the security of the entire network. They often contain the most valuable resources, such as proprietary business documents or personal information and generate interesting network traffic, like email and online purchases. This data can be a target all in itself, but the client can also become an entry point into the network for an attacker. If an attacker can break into a client computer, he can use it as a means to access protected resources throughout the rest of the network. The chapters in this section will show you how to configure client stations securely on a wide range of platforms.
