An introduction to designing and configuring Cisco IPsec VPNs Understand the basics of the IPsec protocol and learn implementation best practices Study up-to-date IPsec design, incorporating current Cisco innovations in the security and VPN marketplace Learn how to avoid common pitfalls related to IPsec deployment Reinforce theory with case studies, configuration examples showing how IPsec maps to real-world solutions IPsec Virtual Private Network Fundamentals provides a basic working knowledge of IPsec on various Cisco routing and switching platforms. It provides the foundation necessary to understand the different components of Cisco IPsec implementation and how it can be successfully implemented in a variety of network topologies and markets (service provider, enterprise, financial, government). This book views IPsec as an emerging requirement in most major vertical markets, explaining the need for increased information authentication, confidentiality, and non-repudiation for secure transmission of confidential data. The book is written using a layered approach, starting with basic explanations of why IPsec was developed and the types of organizations relying on IPsec to secure data transmissions. It then outlines the basic IPsec/ISAKMP fundamentals that were developed to meet demand for secure data transmission. The book covers the design and implementation of IPsec VPN architectures using an array of Cisco products, starting with basic concepts and proceeding to more advanced topics including high availability solutions and public key infrastructure (PKI). Sample topology diagrams and configuration examples are provided in each chapter to reinforce the fundamentals expressed in text and to assist readers in translating concepts into practical deployment scenarios. Additionally, comprehensive case studies are incorporated throughout to map topics to real-world solutions.

This book starts with the basic premise that a service is comprised of the 3Ps-products, processes, and people. Moreover, these entities and their sub-entities interlink to support the services that end users require to run and support a business. This widens the scope of any availability design far beyond hardware and software. It also increases t

An oft-repeated adage among telecommunication providers goes, “There are ve things that matter: reliability, reliability, reliability, time to market, and cost. If you can’t do all ve, at least do the rst three. ” Yet, designing and operating reliable networks and services is a Herculean task. Building truly reliable components is unacceptably expensive, forcing us to c- struct reliable systems out of unreliable components. The resulting systems are inherently complex, consisting of many different kinds of components running a variety of different protocols that interact in subtle ways. Inter-networkssuch as the Internet span multiple regions of administrative control, from campus and cor- rate networks to Internet Service Providers, making good end-to-end performance a shared responsibility borne by sometimes uncooperative parties. Moreover, these networks consist not only of routers, but also lower-layer devices such as optical switches and higher-layer components such as rewalls and proxies. And, these components are highly con gurable, leaving ample room for operator error and buggy software. As if that were not dif cult enough, end users understandably care about the performance of their higher-level applications, which has a complicated relationship with the behavior of the underlying network. Despite these challenges, researchers and practitioners alike have made trem- dous strides in improving the reliability of modern networks and services.

The practical guide to building resilient and highly available IP networks Learn from an all-in-one introduction to new features and developments in building a resilient IP network Enable your organization to meet internal service-level agreements (SLAs) for mission-critical resources Understand how a resilient IP network can help in delivering mission-critical information such as video and voice services Work with configuration examples that are based on real-world issues and customer requirements Get tips and best practices from field personnel who have worked on some of the largest networks with stringent uptime requirements and SLAs More companies are building networks with the intention of using them to conduct business. Because the network has become such a strategic business tool, its availability is of utmost importance to companies and their service providers. The challenges for the professionals responsible for these networks include ensuring that the network remains up all the time, keeping abreast of the latest technologies that help maintain uptime, and reacting to ever-increasing denial-of-service (DoS) attacks. Building Resilient IP Networks helps you meet those challenges. This practical guide to building highly available IP networks captures the essence of technologies that contribute to the uptime of networks. You gain a clear understanding of how to achieve network availability through the use of tools, design strategy, and Cisco IOS® Software. With Building Resilient IP Networks, you examine misconceptions about five-nines availability and learn to focus your attention on the real issues: appreciating the limitations of the protocols, understanding what has been done to improve them, and keeping abreast of those changes. Building Resilient IP Networks highlights the importance of having a modular approach to building an IP network and, most important, illustrates how a modular design contributes to a resilient network. You learn how an IP network can be broken down to various modules and how these modules interconnect with one another. Then you explore new network resiliency features that have been developed recently, categorized with respect to the design modules. Building Resilient IP Networks is relevant to both enterprise and service provider customers of all sizes. Regardless of whether the network connects to the Internet, fortifying IP networks for maximum uptime and prevention of attacks is mandatory for anyone’s business. This book is part of the Networking Technology Series from Cisco Press®, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.
