Overview

The phenomenal growth of the Internet has given rise to a variety of network applications and services that are pervading our daily life at a staggering pace. This trend is being boosted by myriad mobile devices that essentially make it possible to access network resource anywhere, anytime. In parallel, security and privacy issues have surfaced in almost every aspect of the mobile computing paradigm, from wireless communication security to network denial of service (DoS) attacks, to secure network protocols, and to mobile privacy. Furthermore, the inherent characteristics of mobile computing have imposed greater challenges on mobile security and privacy solutions than on general wired network security approaches.

This chapter explores a wide range of mobile security and privacy issues, presents a big picture of this broad area, and offers some insight into the fundamental security problems surrounding the design of secured mobile wireless systems and applications. The chapter begins with a security primer summarizing a set of basic network security concepts and security schemes, followed by an indepth coverage of security issues in cellular networks, wireless LAN, Bluetooth, and other emerging mobile wireless systems. When presenting each topic, we introduce technical aspects of each problem and discuss some proposed approaches for solving it. When possible, we then outline some real-world solutions to the underlying problems. Readers will be able to quickly obtain a solid understanding of key mobile security and the related privacy issues.

The security issues surrounding mobile wireless networks and applications can be categorized as follows:
