In this book, Kaustubh Phaltankar explores the nuances and specifics, in detailed, concrete ways, of designing, constructing, and provisioning secure virtual private networks in the context of network substrates shared among multiple parties, corporate intranets and extranets. In addition to the essential technology with which this book will make readers acquainted, the case studies are among the most valuable of the contributions the book makes to the current network security literature. Understanding how real companies in the real world have dealt with real security challenges is among the most valuable of the lessons that readers can take away from this useful volume. - From the Foreword by Dr. Vinton G. Cerf Senior Vice President of Data Architecture, MCI Data Services Division Codeveloper of the computer networking protocol TCP/IP. This invaluable new book provides hands-on methodology for designing effective network-level security systems for your corporate intranet or extranet. Using real-world examples and referencing the latest intranet and extranet technology, this essential guidebook for IT professionals shows how to configure network and security elements such as routers, switches, servers and firewalls to achieve top-notch security. Components of effective security are critically reviewed in detail, including different types of firewalls, such as Packet Filters, Stateful and Application level proxy devices, and encryption schemes, such as DES, RSA, and IPSEC. Secure data transport and data access are also discussed, as well as the use of remote intelligent agents on network devices and servers. You learn to evaluate security options based on requirements such as cost, complexity, and performance, and network and service management issues. Implementing Secure Intranets and Extranets closes the gap between theory and implementation by featuring detailed case studies and an interactive approach with diagrams and configurations. This is a fundamental resource for IT professionals including engineers, architects and consultants, system administrators, and technical managers.
