Published online by Cambridge University Press: 11 September 2009
Summary
Security of wireless networks has become an important issue recently due to the increased dependence of individuals and organizations on these systems in their daily life. The goal of this chapter is to present the major trends and techniques in the security of wireless local area networks as well as to review the needs for securing access to such systems as any breach to such systems may entail loss of money, risk to the secrets of companies and organizations, as well as national security information. We will review the types of attacks on wireless networks. One section is dedicated to the review of services of any reliable security system that include confidentiality, non repudiation, authentication, access control, integrity, and availability. We will also shed some light on the chief aspects of the Wired Equivalent Privacy (WEP) Protocol and security aspects of mobile IP. The major weakness of the WEP protocol will be investigated. Then, we will review the features of the newly devised WPA protocols that proved to have superior security characteristics. Finally, we shed some light on Virtual Private Networks as related to wireless LAN security.
Introduction and rationale
The growth of Wireless Local Area Networks (WLANs) since the mid 1980s was triggered by the US Federal Communications Commission (FCC) determination to authorize the public use of the Industrial, Scientific and Medical (ISM) bands. This decision abolished the need for companies and end users to obtain FCC licenses in order to operate their wireless products.
