Virtual Private Networks: Enhancing the Impact of the Internet

Abstract

VPN development has been driven by the rapid growth of Internet access, the critical mass of companies with a Web presence or conducting some form of e-commerce over the Internet, and the great concern for saving money. The objectives of this chapter are to provide a brief background on the development and technology of VPNs, describe several current VPN implementations and their impacts, and discuss key management issues surrounding the adoption and implementation of VPNs.
