Download: Wireless Security There's no doubt that mobile computing is booming. This chapter, taken from Cisco Press' NetworkSecurity Fundamentals, covers wireless local area network (WLAN) security--what it is, how it works, how to configure it, what threatens it, and what policies you can design to secure it.
It's in today's tech republic. ITs a whole good chapter on basic wireless security.
