Linux and other Unix-like operating systems are prevalent on the Internet for a number of reasons. As an operating system designed to be flexible and robust, Unix lends itself to providing a wide array of host- and network-based services. Unix also has a rich culture from its long history as a fundamental part of computing research in industry and academia. Unix and related operating systems play a key role as platforms for delivering the key services that make the Internet possible. For these reasons, it is important that information security practitioners understand fundamental Unix concepts in support of practical knowledge of how Unix systems might be securely operated. This chapter is an introduction to Unix in general and to Linux in particular, presenting some historical context and describing some fundamental aspects of the operating system architecture. Considerations for hardening Unix deployments will be contemplated from network-centric, host-based, and systems management perspectives. Finally, proactive considerations are presented to identify security weaknesses to correct them and to deal effectively with security breaches when they do occur.

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.

With an ever increasing amount of information being transmitted electronically, it is important that security be considered in every phase of local area network design and maintenance. Although much emphasis has been placed on such things as wireless networks and remote access, it is imperative that the core local area network not be overlooked. Because the wired local area network is the nervous system of an organization’s Information Systems, great care must be taken to properly secure it. This chapter begins by looking at the implications for the wired local area network infrastructure security. Next, local area network segmentation and traffic isolation will be discussed. By using segmentation and isolation, there is the increased opportunity for security boundaries. Another concept that will be discussed is the security of the local area network equipment. The local area network is only functional if the core equipment is operational, so securing equipment is an important part of any security strategy. To conclude, restriction of local area network access will be investigated and an organizational approach will be discussed. Because more and more users need access to local area network resources, there must be a way to identify and restrict who is allowed on the network and what access they are granted. In wired local area network infrastructure security, organizations must remember they are only as secure as their weakest point. By carefully considering the various aspects of the local area network security during design, these weak points can be reduced and the overall security of the network increased. Although it is impossible to be 100% secure and still be functional, by using some general guidelines to secure the wired local area network, many threats to the network can be reduced if not eliminated.

In recent years, cellular networks have become open public networks to which end subscribers have direct access. This has greatly increased the number of threats to cellular networks. Though cellular networks have vastly advanced in their performance abilities, the security of these networks still remains highly outdated. As a result, they are one of the most insecure networks today – so much so, that using simple off-the-shelf equipment, any adversary can cause major network outages affecting millions of subscribers. In this chapter, we address the security of cellular networks. We also educate readers on the current state of security of cellular networks and their vulnerabilities. In addition, we outline a cellular network specific attack taxonomy–also called the three-dimensional attack taxonomy. Furthermore, we also discuss the vulnerability assessment tools for cellular networks. Finally, we provide insights as to why cellular networks are so vulnerable and why securing them can prevent communication outages during emergencies.

Biometric Technologies and Verification Systems is organized into nine parts composed of 30 chapters, including an extensive glossary of biometric terms and acronyms. It discusses the current state-of-the-art in biometric verification/authentication, identification and system design principles. It also provides a step-by-step discussion of how biometrics works; how biometric data in human beings can be collected and analyzed in a number of ways; how biometrics are currently being used as a method of personal identification in which people are recognized by their own unique corporal or behavioral characteristics; and how to create detailed menus for designing a biometric verification system. Only biometrics verification/authentication is based on the identification of an intrinsic part of a human being. Tokens, such as smart cards, magnetic stripe cards, and physical keys can be lost, stolen, or duplicated. Passwords can be forgotten, shared, or unintentionally observed by a third party. Forgotten passwords and lost "smart cards" are a nuisance for users and an expensive time-waster for system administrators. Biometric security solutions offer some unique advantages for identifying and verifying/ authenticating human beings over more traditional security methods. This book will serve to identify the various security applications biometrics can play a highly secure and specific role in. * Contains elements such as Sidebars, Tips, Notes and URL links * Heavily illustrated with over 150 illustrations, screen captures, and photographs * Details the various biometric technologies and how they work while providing a discussion of the economics, privacy issues and challenges of implementing biometric security solutions
