Computer Incident Response and Product Security The practical guide to building and running incident response and product security teams Damir Rajnovic Organizations increasingly recognize the urgent importance of effective, cohesive, and efficient security incident response. The speed and effectiveness with which a company can respond to incidents has a direct impact on how devastating an incident is on the company’s operations and finances. However, few have an experienced, mature incident response (IR) team. Many companies have no IR teams at all; others need help with improving current practices. In this book, leading Cisco incident response expert Damir Rajnovi´c presents start-to-finish guidance for creating and operating effective IR teams and responding to incidents to lessen their impact significantly. Drawing on his extensive experience identifying and resolving Cisco product security vulnerabilities, the author also covers the entire process of correcting product security vulnerabilities and notifying customers. Throughout, he shows how to build the links across participants and processes that are crucial to an effective and timely response. This book is an indispensable resource for every professional and leader who must maintain the integrity of network operations and products—from network and security administrators to software engineers, and from product architects to senior security executives. -Determine why and how to organize an incident response (IR) team -Learn the key strategies for making the case to senior management -Locate the IR team in your organizational hierarchy for maximum effectiveness -Review best practices for managing attack situations with your IR team -Build relationships with other IR teams, organizations, and law enforcement to improve incident response effectiveness -Learn how to form, organize, and operate a product security team to deal with product vulnerabilities and assess their severity -Recognize the differences between product security vulnerabilities and exploits -Understand how to coordinate all the entities involved in product security handling -Learn the steps for handling a product security vulnerability based on proven Cisco processes and practices -Learn strategies for notifying customers about product vulnerabilities and how to ensure customers are implementing fixes This security book is part of the Cisco Press Networking Technology Series. Security titles from Cisco Press help networking professionals secure critical data and resources, prevent and mitigate network attacks, and build end-to-end, self-defending networks.

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.
