This book describes new approaches to wireless security enabled by the recent development of new core technologies for Wi-Fi/802.11. It shows how the new approaches work and how they should be applied for maximum effect. For system administrators, product designers, or advanced home users.

Focusing on wireless LANs in general and 802.11-based networks in particular, Potter (VeriSign) and Fleck (Secure Software) outline strategies and implementations for deploying a secure wireless network. They explain how the 802.11 protocols work and how an attacker will attempt to exploit weak spots within a network, and suggest methods for locking down a wireless client machine and securely configuring a wireless access point.

As we all know by now, wireless networks offer many advantages over fixed (or wired) networks. Foremost on that list is mobility, since going wireless frees you from the tether of an Ethernet cable at a desk. But that's just the tip of the cable-free iceberg. Wireless networks are also more flexible, faster and easier for you to use, and more affordable to deploy and maintain.The de facto standard for wireless networking is the 802.11 protocol, which includes Wi-Fi (the wireless standard known as 802.11b) and its faster cousin, 802.11g. With easy-to-install 802.11 network hardware available everywhere you turn, the choice seems simple, and many people dive into wireless computing with less thought and planning than they'd give to a wired network. But it's wise to be familiar with both the capabilities and risks associated with the 802.11 protocols. And 802.11 Wireless Networks: The Definitive Guide, 2nd Edition is the perfect place to start.This updated edition covers everything you'll ever need to know about wireless technology. Designed with the system administrator or serious home user in mind, it's a no-nonsense guide for setting up 802.11 on Windows and Linux. Among the wide range of topics covered are discussions on: deployment considerations network monitoring and performance tuning wireless security issues how to use and select access points network monitoring essentials wireless card configuration security issues unique to wireless networks With wireless technology, the advantages to its users are indeed plentiful. Companies no longer have to deal with the hassle and expense of wiring buildings, and households with several computers can avoid fights over who's online. And now, with 802.11 Wireless Networks: The Definitive Guide, 2nd Edition, you can integrate wireless technology into your current infrastructure with the utmost confidence.

The next frontier for wireless LANs is 802.11ac, a standard that increases throughput beyond one gigabit per second. This concise guide provides in-depth information to help you plan for 802.11ac, with technical details on design, network operations, deployment, and monitoring. Author Matthew Gast—an industry expert who led the development of 802.11-2012 and security task groups at the Wi-Fi Alliance—explains how 802.11ac will not only increase the speed of your network, but its capacity as well. Whether you need to serve more clients with your current level of throughput, or serve your existing client load with higher throughput, 802.11ac is the solution. This book gets you started. Understand how the 802.11ac protocol works to improve the speed and capacity of a wireless LAN Explore how beamforming increases speed capacity by improving link margin, and lays the foundation for multi-user MIMO Learn how multi-user MIMO increases capacity by enabling an AP to send data to multiple clients simultaneously Plan when and how to upgrade your network to 802.11ac by evaluating client devices, applications, and network connections

This book provides a concise yet comprehensive overview of computer and Internet security, suitable for a one-term introductory course for junior/senior undergrad or first-year graduate students. It is also suitable for self-study by anyone seeking a solid footing in security – including software developers and computing professionals, technical managers and government staff. An overriding focus is on brevity, without sacrificing breadth of core topics or technical detail within them. The aim is to enable a broad understanding in roughly 350 pages. Further prioritization is supported by designating as optional selected content within this. Fundamental academic concepts are reinforced by specifics and examples, and related to applied problems and real-world incidents. The first chapter provides a gentle overview and 20 design principles for security. The ten chapters that follow provide a framework for understanding computer and Internet security. They regularly refer back to the principles, with supporting examples. These principles are the conceptual counterparts of security-related error patterns that have been recurring in software and system designs for over 50 years. The book is “elementary” in that it assumes no background in security, but unlike “soft” high-level texts it does not avoid low-level details, instead it selectively dives into fine points for exemplary topics to concretely illustrate concepts and principles. The book is rigorous in the sense of being technically sound, but avoids both mathematical proofs and lengthy source-code examples that typically make books inaccessible to general audiences. Knowledge of elementary operating system and networking concepts is helpful, but review sections summarize the essential background. For graduate students, inline exercises and supplemental references provided in per-chapter endnotes provide a bridge to further topics and a springboard to the research literature; for those in industry and government, pointers are provided to helpful surveys and relevant standards, e.g., documents from the Internet Engineering Task Force (IETF), and the U.S. National Institute of Standards and Technology.

Finally--a single volume guide to really effective security for both voice and data wireless networks! More and more data and voice communications are going via wireless at some point between the sender and intended recipient. As a result, truly "bulletproof" wireless security is now more than a desirable feature--instead, it's a necessity to protect essential personal and business data from hackers and eavesdroppers. In this handy reference, Praphul Chandra gives you the conceptual and practical tools every RF, wireless, and network engineer needs for high-security wireless applications. Inside this book you'll find coverage of these essential topics: + Cryptographic protocols used in wireless networks. + Key-based protocols, including key exchange and authentication techniques + Various types of wireless network attacks, including reflection, session hijacks, and Fluhrer-Mantin-Shamir (FMS) attacks. + Encryption/decryption standards and methods. + Multi-layered security architectures. + Secure sockets layer (SSL) and transport layer security (TLS) protocols. + Cellular telephone network architectures and their vulnerabilities. + Modulation techniques, such as direct-sequence spread spectrum (DSSS) and orthogonal frequency division multiplexing (OFDM) And you'll also find coverage on such cutting-edge topics as security techniques for ad hoc networks and protecting Bluetooth networks. If you're serious about wireless security, then this title belongs on your reference bookshelf!

This comprehensive wireless network book addresses the operational and day-to-day security management requirements of 21st century companies. Wireless networks can easily be reconfigured, are very mobile, allow for potentially nonstop exposure, and require the level of security be scrutinized even more than for wired networks. This includes inherent security flaws in various wireless architectures that result in additional risks to otherwise secure converged wired networks. An even worse scenario is one where an insecure wireless network is connected to a weakly secured or insecure wired network and the wireless subnet is not separated from the wired subnet. There are approximately a dozen popular books that cover components of the architecture, design, theory, issues, challenges, and recommended policies for wireless security, none of which address them in a practical, operationally-oriented and comprehensive way. Wireless Operational Security bridges this gap.*Presents a new "WISDOM" model for Wireless Security Infrastructures*Acts as a critical guide to implementing "Converged Networks" wired/wireless with all necessary security considerations*Rittinghouse's Cybersecurity Operations Handbook is the only security book recommended by the FCC
