With the convenience of wireless technologies comes a new host of security problems. Unlike wired networks where security involves limiting physical access to routers, hubs, and cables, wireless networks' most vulnerable point (the radio waves floating through the air) has no physical substance, so securing wireless networks is a challenging task.
In this book, I take a look at the various ways to secure wireless networks, using standards such as Wired Equivalent Privacy (WEP), Wireless Protected Access (WPA), 802.1X, and 802.11i.
In addition, I also look at the security features found in the Bluetooth and Infrared technologies. Chapter 4 discusses what you need to know to communicate securely.
