A major, comprehensive professional text/reference for designing and maintaining security and reliability. From basic concepts to designing principles to deployment, all critical concepts and phases are clearly explained and presented. Includes coverage of wireless security testing techniques and prevention techniques for intrusion (attacks). An essential resource for wireless network administrators and developers.

This guide presents real-world hacking scenarios along with complete implementation guidance for the right NAP/NAC solution, so you can understand which solution makes the most sense based upon the most prevalent risks in your environment. Follow the actual steps hackers take to perform specific exploits, determine which security solutions will stop the exploits from happening, and learn all about the standard components of any NAP/NAC solution. By learning to analyze a security posture, set policies for device analysis, and communicate with the device, you?ll be able to take action.

Wireless Local Area Networks (WLANs), widely prevalent in corporate environments, is a current giant leap in information technology. This new paradigm of communications has leverage over other ways of data transmission, because it enables businesses and corporate environments to operate in a fast, better and more profitable way. Through the use of always-on, always-connected and always-available content and applications, WLAN combines data connectivity with user mobility. The IEEE standard for wireless LAN is 802.11. The 802.11 is emerging as a significant aspect of Internetworking. Growing rapidly in the wireless local area network environment, 802.11s are easy to find, because wireless technology allows the network to go where wire cannot. This fact, however, raises a number of security concerns. The current security solutions offered on a private 802.11 network in a public setting are not sufficient to protect sensitive material, so other measures are needed to provide adequate protection for data passed over the air. Although encryption, authentication and authorization are the pillars of security, there are other techniques that can be used and implemented for network defense. Security concerns have evolved, because there are limitations and weaknesses in controlling access and there are flaws and vulnerabilities in WEP data encryption. These things add to the insecure nature of radio broadcast transmission. This study discusses some security models offered over wireless networks and integrates the security enhancement by combining some of the wired techniques such as adding Kerberos to the wireless security equation along with RADIUS for increased authentication and authorization so that compromising the network is a non-trivial task. Those models are designed to prevent unauthorized access to the network from outside the wireless network environment. While we can make intrusion difficult, we cannot prevent hackers with portable devices and scanners from intercepting data and gaining access to the network. If we want flexibility and mobility, we can have this, but not with total security. The 802.11 technology protection is not failsafe as long as there is technology that allows portable computing devices with scanners to gain access to the LAN or intercept data.

This book identifies vulnerabilities in the physical layer, the MAC layer, the IP layer, the transport layer, and the application layer, of wireless networks, and discusses ways to strengthen security mechanisms and services. Topics covered include intrusion detection, secure PHY/MAC/routing protocols, attacks and prevention, immunization, key management, secure group communications and multicast, secure location services, monitoring and surveillance, anonymity, privacy, trust establishment/management, redundancy and security, and dependable wireless networking.

Security Smarts for the Self-Guided IT Professional Protect wireless networks against all real-world hacks by learning how hackers operate. Wireless Network Security: A Beginner's Guide discusses the many attack vectors that target wireless networks and clients--and explains how to identify and prevent them. Actual cases of attacks against WEP, WPA, and wireless clients and their defenses are included. This practical resource reveals how intruders exploit vulnerabilities and gain access to wireless networks. You'll learn how to securely deploy WPA2 wireless networks, including WPA2-Enterprise using digital certificates for authentication. The book provides techniques for dealing with wireless guest access and rogue access points. Next-generation wireless networking technologies, such as lightweight access points and cloud-based wireless solutions, are also discussed. Templates, checklists, and examples give you the hands-on help you need to get started right away. Wireless Network Security: A Beginner's Guide features: Lingo--Common security terms defined so that you’re in the know on the job IMHO--Frank and relevant opinions based on the author's years of industry experience In Actual Practice--Exceptions to the rules of security explained in real-world contexts Your Plan--Customizable checklists you can use on the job now Into Action--Tips on how, why, and when to apply new skills and techniques at work This is an excellent introduction to wireless security and their security implications. The technologies and tools are clearly presented with copious illustrations and the level of presentation will accommodate the wireless security neophyte while not boring a mid-level expert to tears. If the reader invests the time and resources in building a lab to follow along with the text, s/he will develop a solid, basic understanding of what "wireless security" is and how it can be implemented in practice. This is definitely a recommended read for its intended audience. - Richard Austin, IEEE CIPHER, IEEE Computer Society's TC on Security and Privacy (E109, July 23, 2012)
