My presentation will be on Virtual Private Networks (VPN). I will give and overview of
several major types of VPN including client to network and network to network using
PPTP (client to network only), IPSec and OpenVPN. I will also cover the basics of
symmetric and asymmetric encryption as well as implementations of PPTP (built into
Windows, poptop for Linux) and IPSec (Cisco VPNClient, Netopia Routers, openSwan).
