Guide Review - "Virtual Private Networks" by Dennis Fowler
Finding well-written, unbiased information about Virtual Private Networking is difficult, primarily because VPNs by their nature are not easy to explain. A "network within a network," VPNs utilize the concept of "tunneling" to transmit private communications over public lines. A VPN system depends on fairly complex low-level networking technologies including specialized protocols. The details of network design, security, and administration can seem intimidating at first.
VPNs require careful planning on behalf of the companies that choose to implement them. This book offers the network architect, project manager, or engineer the information they need to understand the potential of and issues associated with Virtual Private Networks.
