Description:
Virtual Private Networks (VPNs) are simply a means of creating a private and secure wide area network (WAN) based on public network infrastructures. A company can create its own VPN using the Internet or by buying VPN services from a provider. It's difficult to write a static book on a moving target: Dennis Fowler addresses this problem in Virtual Private Networks: Making the Right Connection by dealing heavily in concepts, benefits, and standards while spending less time on specific VPN technology solutions. The book begins, sensibly, by considering VPN cost savings over traditional WAN solutions. These range from 20 percent to 80 percent, depending on the activity. Many company decision makers won't reach chapter 2. At this point, Fowler's book is likely to find its way down through company ranks to those who deal with people-based networking issues, costs, and planning--until it finally ends up on the desk of a hands-on system manager. In fact, the book appears to be structured with this very sequence in mind. Virtual Private Networks is short enough to be read in a weekend. But its broad approach will ensure that managers will come away sufficiently informed to make a valid decision about the place of VPNs in their enterprise. --Steve Patient, amazon.co.uk
