True enough: every situation that calls for a VPN is different; and, if the book had shown how to implement a VPN with one turnkey solution, users of the others would complain. But even the narrowest example would have been better than some of the stuff that fills these pages. At one point, the reader is walked through the process of encoding and decoding a plain-text message--by hand--by using a shared private key. Spare us, please. The book gives the vital Layer 2 Transport Protocol all of two short paragraphs. Sections on public-key encryption and digital certificates do a good job of unraveling perennially misunderstood processes, but they don't offset the lack of details on VPN. --David Wall
Topics covered: Aspects of virtual private networks (VPNs), organized to get potential VPN implementers thinking about security and other design issues. Specifically, Public-Key Infrastructure (PKI); digital certificates; turnkey VPN packages; and a lot of general stuff about what VPNs are good for, and how to design a good one.
