Wireless LANs are becoming ubiquitous. From hotel lobbies to Starbucks coffee shops, to airports and offices, it is difficult not to be able to pick up a wireless LAN signal. Accompanying the growth in the use of wireless LANs is a recognition that as initially designed they are not secure.
The focus of this book is upon wireless LAN security. In this book we will examine how wireless LANs operate, with special attention focused upon the manner in which security occurs under the IEEE 802.11 wireless LAN standard and its extensions, and why the standard and its extensions are weak. We will use this information to note many vulnerabilities associated with the use of wireless LANs and the security risks that can occur via an over-the-air
transmission method. Because network managers and LAN administrators, as well as small business and home users of wireless LANs, need to know how to overcome the security limitations of wireless LANs, several chapters in this book are devoted to security enhancement techniques. One chapter is focused upon vendor-specific solutions, while a second chapter examines the use of existing and evolving standards that can be employed to literally harden your wireless LAN.
