If a network is not secure, how valuable is it? Introduction to Computer Networks and Cybersecurity takes an integrated approach to networking and cybersecurity, highlighting the interconnections so that you quickly understand the complex design issues in modern networks. This full-color book uses a wealth of examples and illustrations to effectively connect the principles of networks and networking protocols with the relevant cybersecurity issues. Get the Fundamentals of Internet Architecture and the Protocol Layers Organized into six parts, the book walks you through the fundamentals, starting with the way most people first encounter computer networks—through the Internet architecture. Part 1 covers the most important Internet applications and the methods used to develop them. Part 2 discusses the network edge, consisting of hosts, access networks, LANs, and the physical media used with the physical and link layers. Part 3 explores the network core, including packet/circuit switches, routers, and the Internet backbone, and Part 4 examines reliable transport and the management of network congestion. Learn about Malware and Security Systems Building on the concepts and principles, the book then delves into state-of-the-art cybersecurity mechanisms in Part 5. It reviews the types of malware and the various security systems, made up of firewalls, intrusion detection systems, and other components. Crucially, it provides a seamless view of an information infrastructure in which security capabilities are built in rather than treated as an add-on feature. The book closes with a look at emerging technologies, including virtualization and data center and cloud computing unified communication. Understand Cyber Attacks—and What You Can Do to Defend against Them This comprehensive text supplies a carefully designed introduction to both the fundamentals of networks and the latest advances in Internet security. Addressing cybersecurity from an Internet perspective, it prepares you to better understand the motivation and methods of cyber attacks and what you can do to protect the networks and the applications that run on them. Pedagogical Features The book’s modular design offers exceptional flexibility, whether you want to use it for quick reference, self-study, or a wide variety of one- or two-semester courses in computer networks, cybersecurity, or a hybrid of both. Learning goals in each chapter show you what you can expect to learn, and end-of-chapter problems and questions test your understanding. Throughout, the book uses real-world examples and extensive illustrations and screen captures to explain complicated concepts simply and clearly. Ancillary materials, including PowerPoint® animations, are available to instructors with qualifying course adoption.

Networks for Computer Scientists and Engineers is a data communications and networks textbook with a unique software projects and laboratory-based approach. Due to its innovative and distinctive features, it has won unanimous recommendation and partial sponsorship by the curriculum development committee of the National Science Foundation. Designed for undergraduate students, it covers both fundamental theory and modern technologies. The Instructor's Manual and CD (available to adopters) provide step-by-step instructions for configuring client/server computers, hubs, routers, and switches to construct a cost-effective prototype network lab with implementation of web (http), email, VPN, and other servers. This prototype lab is based on Linux and other popular platforms, demonstrates how different protocols and components are integrated into a heterogeneous network, and provides an ideal environment for troubleshooting and experimental network management. The book's accompanying software projects--included on the instructor's CD--are not merely samples but complete software packages with real applications and utilities written in Java, C, C++, assembly language, and thoroughly tested by professors and students at several universities. Used together, Networks for Computer Scientists and Engineers and the accompanying laboratory projects actively engage students in the learning process and provide opportunities for critical thinking, problem solving, and creativity in a controlled real-world setting. Features · Covers LAN, WAN, wireless, and high-speed networking technologies; OSI seven layers; data communications; and network performance, programming, management, and security · Includes networking projects with directions and sample solutions · Features numerous figures, examples, summaries, review questions, references, and a glossary · Contains problem sets and up-to-date World Wide Web sites related to each chapter · Provides answers to the review questions and step-by-step instructions in the accompanying Instructor's Manual

Once again, Bud Bates brings you the most comprehensive and definitive reference covering the latest in networking and telecommunications technologies. Updated to cover wireless protocols, optical networking, and high-speed broadband services this easy-to-understand resource contains comprehensive coverage of this fast-growing industry. Learn everything from basic concepts to practical implementation techniques--all presented in a straightforward and jargon-free style.
Written for students and managers who do not have a technical background, Data Communications and Network Security comprehensively introduces students to the technology and management of data communications. This includes both wired and wireless technology as well as comprehensive coverage of network security, helping both the organization and the individual create and maintain a data-safe environment. The book's unique organization allows the material to be presented in a variety of ways, making the book a strong match to any teaching approach.
Primarily intended as a text for undergraduate courses in Electronics and Communications Engineering, Computer Science, IT courses, and Computer Applications, this up-to-date and accessible text gives an indepth analysis of data communications and computer networks in an easy-to-read style. Though a new title, it is a completely revised and fully updated version of the author's earlier book Data Communications. The rapid strides made during the last decade in the fields of data communication and networking, and the close link between these two subjects have prompted the author to add several chapters on computer networks in this text. The book gives a masterly analysis of topics ranging from the principles of data transmission to computer networking applications. It also provides standard protocols, thereby enabling to bridge the gap between theory and practice. What's more, it correlates the network protocols to the concepts, which are explained with the help of numerous examples to facilitate students' understanding of the subject. This well-organized text presents the latest developments in the field and details current topics of interest such as Multicasting, MPLS, IPv6, Gigabit Ethernets, IPSec, SSL, Auto-negotiation, Wireless LANs, Network security, Differentiated services, and ADSL. Besides students, the practicing professionals would find the book to be a valuable resource.

This book introduces different interconnection networks applied to different systems. Interconnection networks are used to communicate processing units in a multi-processor system, routers in communication networks, and servers in data centers. Queuing techniques are applied to interconnection networks to support a higher utilization of resources. There are different queuing strategies, and these determine not only the performance of the interconnection network, but also the set of requirements to make them work effectively and their cost. Routing algorithms are used to find routes to destinations and directions in what information travels. Additional properties, such as avoiding deadlocks and congestion, are sought. Effective routing algorithms need to be paired up with these networks. The book will introduce the most relevant interconnection networks, queuing strategies, and routing algorithm. It discusses their properties and how these leverage the performance of the whole interconnection system. In addition, the book covers additional topics for memory management and congestion avoidance, used to extract higher performance from the interconnection network.
