Guide Review - How Secure is Your Wireless Network - Safeguarding Your Wi-Fi LAN
The early chapters describe the design of Wi-Fi communication standards and security technologies like WEP and WPA. Later chapters build on this foundation, providing step-by-step instructions for setting up and managing more secure WLANs. The tasks of connecting a WLAN to a wired network, and installing VPN servers and clients, are especially well described. The author even reveals how to build a Wi-Fi antenna from a potato chip can!
