The adoption of wireless devices continues to grow as they become more affordable. The rapid spread of wireless technologies among both business and personal systems has improved interoperability and accessibility. However, this very ubiquity has also led to an increase in the number of threats to computer networks. Wireless technologies have given attackers new ways to steal sensitive information, tamper with business processes, and subvert network security enforcement mechanisms. As new threats and attacks are found against wireless networks, they are addressed with changes and additions to the protocols and standards. This book will introduce the basic concepts underlying the evolution of wireless security-the threats, the exploits, and the remediation strategies.

WEP WEP (Wired Equivalent Privacy) is a deprecated algorithm to secure IEEE 802.11 wireless networks. Wireless networks broadcast messages using radio and are thus more susceptible to eavesdropping than wired networks. WEP was proposed to give confidentiality comparable to that of a classic wired network.

To address the confidentiality issues of trade wireless networks, the 802.11 standard includes a simple mechanism for encryption of data, it is Wired Equivalent Privacy.
