Download or read book 802 1X Port Based Authentication written by Edwin Lyle Brown and published by CRC Press. This book was released on 2006-12-19 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Port-based authentication is a "network access control" concept in which a particular device is evaluated before being permitted to communicate with other devices located on the network. 802.1X Port-Based Authentication examines how this concept can be applied and the effects of its application to the majority of computer networks in existence today. 802.1X is a standard that extends the Extensible Authentication Protocol (EAP) over a Local Area Network (LAN) through a process called Extensible Authentication Protocol Over LANs (EAPOL). The text presents an introductory overview of port-based authentication including a description of 802.1X port-based authentication, a history of the standard and the technical documents published, and details of the connections among the three network components. It focuses on the technical aspect of 802.1X and the related protocols and components involved in implementing it in a network. The book provides an in-depth discussion of technology, design, and implementation with a specific focus on Cisco devices. Including examples derived from the 802.1X implementation, it also addresses troubleshooting issues in a Cisco environment. Each chapter contains a subject overview. Incorporating theoretical and practical approaches, 802.1X Port-Based Authentication seeks to define this complex concept in accessible terms. It explores various applications to today's computer networks using this particular network protocol.

Download or read book 802 11 Wireless Networks The Definitive Guide written by Matthew S. Gast and published by "O'Reilly Media, Inc.". This book was released on 2005-04-25 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Wireless Operational Security written by John Rittinghouse PhD CISM and published by Elsevier. This book was released on 2004-05-01 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book The Effective CISSP Security and Risk Management written by Wentz Wu and published by . This book was released on 2020-04-27 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Start with a Solid Foundation to Secure Your CISSP! The Effective CISSP: Security and Risk Management is for CISSP aspirants and those who are interested in information security or confused by cybersecurity buzzwords and jargon. It is a supplement, not a replacement, to the CISSP study guides that CISSP aspirants have used as their primary source. It introduces core concepts, not all topics, of Domain One in the CISSP CBK - Security and Risk Management. It helps CISSP aspirants build a conceptual security model or blueprint so that they can proceed to read other materials, learn confidently and with less frustration, and pass the CISSP exam accordingly. Moreover, this book is also beneficial for ISSMP, CISM, and other cybersecurity certifications. This book proposes an integral conceptual security model by integrating ISO 31000, NIST FARM Risk Framework, and PMI Organizational Project Management (OPM) Framework to provide a holistic view for CISSP aspirants. It introduces two overarching models as the guidance for the first CISSP Domain: Wentz's Risk and Governance Model. Wentz's Risk Model is based on the concept of neutral risk and integrates the Peacock Model, the Onion Model, and the Protection Ring Model derived from the NIST Generic Risk Model. Wentz's Governance Model is derived from the integral discipline of governance, risk management, and compliance. There are six chapters in this book organized structurally and sequenced logically. If you are new to CISSP, read them in sequence; if you are eager to learn anything and have a bird view from one thousand feet high, the author highly suggests keeping an eye on Chapter 2 Security and Risk Management. This book, as both a tutorial and reference, deserves space on your bookshelf.
Download or read book Zero Trust Networks written by Evan Gilman and published by "O'Reilly Media, Inc.". This book was released on 2017-06-19 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it. The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. Understand how perimeter-based defenses have evolved to become the broken model we use today Explore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty) Get example configuration for open source tools that you can use to build a zero trust network Learn how to migrate from a perimeter-based network to a zero trust network in production
