Building a Secure Enterprise Grade VPN

Author: Ian C. Rudy Published May 20, 2011 from SANS

The rising popularity of Virtual Private Networks (VPN) has given birth to a new technology architecture from Cisco Systems that takes these same VPN concepts and encompasses the additional voice and video requirements into a technology called Voice and Video Enabled IPSec VPN or V3PN. This V3PN concept is in fact just a combination of Voice over IP (VoIP) technologies, Quality of Service (QoS) technologies, and Security services into one architectural view. The purpose of this paper is to demonstrate a secure, scalable, and redundant V3PN architecture that can be used as a model for implementation in the Enterprise.
