    What you need to learn to pass a Cisco certification exam such as CCNA and what you need to know to survive in the real world are two very different things. The strategies that this book offers weren 't on the exam, but they 're exactly what you need to do your job well.Network Warrior takes you step by step through the world of hubs, switches, firewalls, and more, including ways to troubleshoot a congested network, and when to upgrade and why. Along the way, you 'll gain an historical perspective of various networking features, such as the way Ethernet evolved. Based on the author 's own experience as well as those he worked for and with, Network Warrior is a Cisco-centric book, focused primarily on the TCP/IP protocol and Ethernet networks -- the realm that Cisco Systems now dominates. The book covers: The type of networks now in use, from LANs, WANs and MANs to CANsThe OSI Model and the layers involved in sending data Hubs, repeaters, switches, and trunks in practice Auto negotiation and why it 's a common problem in network slowdowns Route maps, routing protocols, and switching algorithms in Cisco routers The resilient Ethernet -- how to make things truly redundant Cisco 6500 multi-layer switches and the Catalyst 3750 switch Telecom nomenclature -- why it 's different from the data world T1 and DS3 Firewall theory, designing access lists, authentication in Cisco devices Server load balancing technology Content switch module in action Designing QOS and what QOS does not do IP design and subnetting made easy The book also explains how to sell your ideas to management, how networks become a mess as a company grows, and why change control is your friend. Network Warrior will help network administrators and engineers win the complex battles they face every day.

    In eight chapters, it provides the most thorough coverage of TCP available. It also covers the newest TCP/IP features, including multicasting, path MTU discovery and long fat pipes. The author describes various protocols, including ARP, ICMP and UDP. He utilizes network diagnostic tools to actually show the protocols in action. He also explains how to avoid silly window syndrome (SWS) by using numerous helpful diagrams. This book gives you a broader understanding of concepts like connection establishment, timeout, retransmission and fragmentation. It is ideal for anyone wanting to gain a greater understanding of how the TCP/IP protocols work.

    It guides you through everything you need to know to get started, including how to configure IPv6 on hosts and routers and which applications currently support IPv6. The new IPv6 protocols offers extended address space, scalability, improved support for security, real-time traffic support, and auto-configuration so that even a novice user can connect a machine to the Internet. Aimed at system and network administrators, engineers, network designers, and IT managers, this book will help you understand, plan for, design, and integrate IPv6 into your current IPv4 infrastructure.Beginning with a short history of IPv6, author Silvia Hagen provides an overview of new functionality and discusses why we need IPv6. Hagen also shares exhaustive discussions of the new IPv6 header format and Extension Headers, IPv6 address and ICMPv6 message format, Security, QoS, Mobility and, last but not least, offers a Quick Start Guide for different operating systems. IPv6 Essentials, Second Edition also covers:In-depth technical guide to IPv6 Mechanisms and Case Studies that show how to integrate IPv6 into your network without interruption of IPv4 services Routing protocols and upper layer protocols Security in IPv6: concepts and requirements. Includes the IPSEC framework and security elements available for authentication and encryption Quality of Service: covers the elements available for QoS in IPv6 and how they can be implemented Detailed discussion of DHCPv6 and Mobile IPv6 Discussion of migration cost and business case Getting started on different operating systems: Sun Solaris, Linux, BSD, Windows XP, and Cisco routersWhether you're ready to start implementing IPv6 today or are planning your strategy for the future, IPv6 Essentials, Second Edition will provide the solid foundation you need to get started."Silvia's look at IPv6 is always refreshing as she translates complex technology features into business drivers and genuine end-user benefits to enable building new business concepts based on end to end models." Latif Ladid, President IPv6 Forum, Chair EU IPv6 Task Force

    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. This practical book introduces you to the zero trust model, a method that treats all hosts as if they're internet-facing, and considers the entire network to be compromised and hostile.Authors Evan Gilman and Doug Barth show you how zero trust lets you focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. You'll learn the architecture of a zero trust network, including how to build one using currently available technology.Understand how the zero trust model embeds security within the system's operation, rather than layering it on topExamine the fundamental concepts at play in a zero trust network, including network agents and trust enginesUse existing technology to establish trust among the actors in a networkLearn how to migrate from a perimeter-based network to a zero trust network in productionExplore case studies of zero trust on the client side (Google) and on the server (PagerDuty)

    This expanded and completely updated edition covers the why of network design, focusing not just the specifications comprising today's systems but how key technologies and protocols actually work in the real world to solve specific problems. It is the only introductory computer networking book written by authors who have had first-hand experience with many of the protocols discussed in the text, who have actually designed some of them as well, and who are still actively designing the computer networks today.The book makes less use of computer code to explain protocols than earlier editions. Moreover, this new edition shifts the focus somewhat higher in the protocol stack where there is generally more innovative and exciting work going on at the application and session layers than at the link and physical layers. Other new features are: increased accessibility by clearly separating the advanced material from more fundamental via special headings and boxed features; the material is structured in such a way as to make it easier to teach top-down. Furthermore, the book outstrips the competitors in offering a more robust ancillary package for student and instructor support. The text is complemented with figures as well as links to networking resources on the Web and links to author-created materials on author-maintained Web site.Computer Networks, Fourth Edition, will be an invaluable resource for networking professionals and upper level undergraduate and graduate students in CS, EE, and CSE programs.

    TCP/IP Protocol Suite teaches students and professionals, with no prior knowledge of TCP/IP, everything they need to know about the subject. This comprehensive book uses hundreds of figures to make technical concepts easy to grasp, as well as many examples, which help tie the material to the real-world. The second edition of TCP/IP Protocol Suite has been fully updated to include all of the recent technology changes in the field. Many new chapters have been added such as one on Mobile IP, Multimedia and Internet, Network Security, and IP over ATM. Additionally, out-of-date material has been overhauled to reflect recent changes in technology.

    This book reducesthe investigative workload of computer security incident response teams(CSIRT) by posturing organizations for incident response success.Firewalls can fail. Intrusion-detection systems can be bypassed. Networkmonitors can be overloaded. These are the alarming but true facts aboutnetwork security. In fact, too often, security administrators' tools can serve asgateways into the very networks they are defending.Now, a novel approach to network monitoring seeks to overcome theselimitations by providing dynamic information about the vulnerability of allparts of a network. Called network security monitoring (NSM), it draws on acombination of auditing, vulnerability assessment, intrusion detection andprevention, and incident response for the most comprehensive approach tonetwork security yet. By focusing on case studies and the application of opensourcetools, the author helps readers gain hands-on knowledge of how tobetter defend networks and how to mitigate damage from security incidents.
