Chapter 1. Overview of VPNs
This chapter introduces the concepts of virtual private networks (VPNs) and why they are used. I examine issues with sending traffic across public networks and what VPNs can do to protect this traffic. I introduce connection methods for VPNs, types of VPNs, things to consider when using VPNs, VPN components, VPN designs and issues, examples of VPN implementations, and some issues to consider when choosing a VPN implementation. Further chapters in this book expand on the topics introduced here.
