IPSec VPN Design is the first book to present a detailed examination of the design aspects of IPSec protocols that enable secure VPN communication. VPNs provide productivity enhancements, efficient and convenient remote access to network resources, site-to-site connectivity, a high level of security, and tremendous cost savings. Although several technologies exist that can enable interconnectivity among business sites, Internet-based virtual private networks (VPNs) have evolved as the most effective means to link corporate network resources to remote employees, offices, and mobile workers. Such connectivity is now vital to maintaining a competitive level of business productivity.
Understand how network-based VPNs operate and how to integrate IPSec VPNs with MPLS VPNsĪmong the many functions that networking technologies permit is the ability for organizations to easily and securely communicate with branch offices, mobile users, telecommuters, and business partners.Add services to IPSec VPNs, including voice and multicast.Employ mechanisms to alleviate the configuration complexity of a large- scale IPSec VPN, including Tunnel End-Point Discovery (TED) and Dynamic Multipoint VPNs (DMVPN).Apply fault tolerance methods to IPSec VPN designs.Examine the pros and cons of various IPSec connection models such as native IPSec, GRE, and remote access.Explore IPSec remote-access features, including extended authentication, mode-configuration, and digital certificates.
