This book brings together a number of papers that represent seminal contributions underlying mobile and wireless network security and privacy. It provides a foundation for implementation and standardization as well as further research. The diverse topics and protocols described in this book give the reader a good idea of the current state-of-the-art technologies in mobile and wireless network security and privacy.

With our modern society' s increased dependence on information technology and communication networks, the subject of network security is developing into a crucial base technology and most people working in the networking and information technology business will need to know the basics of fixed and wireless network security.? This book?gives a firm introduction into the field covering the fundamentals of data security technology and explaining in-depth how they are applied in communication networks. Approaches network security from the wireless as well as the computer networking side. Concentrates on the core networking issues (first 4 layers up to the transport layer). Helps the reader to understand the risks of a lack of security in a network & how to prevent it. Brings security in networks up to date by covering wireless and mobile security issues. Includes security issues around hot topics such as wireless LANs (e.g. 802.11), AAA (Authentication, authorization, and accounting), and Mobile IP. Illustrates complicated security concepts with exercises and features an extensive glossary. An essential reference tool for graduate students of computer science, electrical engineering and telecommunications who need to learn the basics of network security. Also, professionals working in data- & telecommunications will also benefit from the book as it gives a self-contained introduction to the basics of network security: network managers, engineers, IT managers.

Wireless Network Security Theories and Applications discusses the relevant security technologies, vulnerabilities, and potential threats, and introduces the corresponding security standards and protocols, as well as provides solutions to security concerns. Authors of each chapter in this book, mostly top researchers in relevant research fields in the U.S. and China, presented their research findings and results about the security of the following types of wireless networks: Wireless Cellular Networks, Wireless Local Area Networks (WLANs), Wireless Metropolitan Area Networks (WMANs), Bluetooth Networks and Communications, Vehicular Ad Hoc Networks (VANETs), Wireless Sensor Networks (WSNs), Wireless Mesh Networks (WMNs), and Radio Frequency Identification (RFID). The audience of this book may include professors, researchers, graduate students, and professionals in the areas of Wireless Networks, Network Security and Information Security, Information Privacy and Assurance, as well as Digital Forensics. Lei Chen is an Assistant Professor at Sam Houston State University, USA; Jiahuang Ji is an Associate Professor at Sam Houston State University, USA; Zihong Zhang is a Sr. software engineer at Jacobs Technology, USA under NASA contract.

Receive comprehensive instruction on the fundamentals of wireless security from three leading international voices in the field Security in Wireless Communication Networks delivers a thorough grounding in wireless communication security. The distinguished authors pay particular attention to wireless specific issues, like authentication protocols for various wireless communication networks, encryption algorithms and integrity schemes on radio channels, lessons learned from designing secure wireless systems and standardization for security in wireless systems. The book addresses how engineers, administrators, and others involved in the design and maintenance of wireless networks can achieve security while retaining the broadcast nature of the system, with all of its inherent harshness and interference. Readers will learn: A comprehensive introduction to the background of wireless communication network security, including a broad overview of wireless communication networks, security services, the mathematics crucial to the subject, and cryptographic techniques An exploration of wireless local area network security, including Bluetooth security, Wi-Fi security, and body area network security An examination of wide area wireless network security, including treatments of 2G, 3G, and 4G Discussions of future development in wireless security, including 5G, and vehicular ad-hoc network security Perfect for undergraduate and graduate students in programs related to wireless communication, Security in Wireless Communication Networks will also earn a place in the libraries of professors, researchers, scientists, engineers, industry managers, consultants, and members of government security agencies who seek to improve their understanding of wireless security protocols and practices.

Wireless communications offer organizations and users many benefits such as portability and flexibility, increased productivity, and lower installation costs. Wireless technologies cover a broad range of differing capabilities oriented toward different uses and needs. This chapter classifies wireless network security threats into one of nine categories: Errors and omissions; fraud and theft committed by authorized or unauthorized users of the system; employee sabotage; loss of physical and infrastructure support; malicious hackers; industrial espionage; malicious code; foreign government espionage; and, threats to personal privacy. All of the preceding represent potential threats to wireless networks. However, the more immediate concerns for wireless communications are fraud and theft, malicious hackers, malicious code, and industrial and foreign espionage. Theft is likely to occur with wireless devices due to their portability. Authorized and unauthorized users of the system may commit fraud and theft; however, the former are more likely to carry out such acts. Since users of a system may know what resources a system has and the system security flaws, it is easier for them to commit fraud and theft. Malicious hackers, sometimes called crackers, are individuals who break into a system without authorization, usually for personal gain or to do harm. Malicious hackers are generally individuals from outside of an organization (although users within an organization can be a threat as well). Such hackers may gain access to the wireless network access point by eavesdropping on wireless device communications. Malicious code involves viruses, worms, Trojan horses, logic bombs, or other unwanted software that is designed to damage files or bring down a system. Industrial and foreign espionage involve gathering proprietary data from corporations or intelligence information from governments through eavesdropping. In wireless networks, the espionage threat stems from the relative ease in which eavesdropping can occur on radio transmissions. This chapter provides an overview of wireless networking security technologies most commonly used in an office environment and by the mobile workforce of today. Also, this chapter seeks to assist organizations in reducing the risks associated with 802.11 wireless LANs, cellular networks, wireless ad hoc networks and for ensuring security when using handheld devices.
