Description:
You may have heard something about virtual private networks (VPNs) and have an inkling that your organization could benefit by implementing one. Or you may know for certain that your company needs a VPN but require some help outlining how in terms decision makers can understand. In both cases, Building and Managing Virtual Private Networks presents the key technical and business information you need. Dave Kosiur explains the business case for VPNs, their potential for saving money, and various means of ensuring security (including encryption and hardware-based systems). He also provides details on all major tunneling protocol suites, including Internet Protocol Security Architecture (IPSec), Point-to-Point Tunneling Protocol (PPTP), and Layer 2 Tunneling Protocol (L2TP). Users will learn how to identify the factors that will affect VPN design and how to select products (including firewalls), services (especially ISPs), and policies that fit their needs. Building and Managing Virtual Private Networks helps you make a go/no-go decision on a VPN for your organization; then it helps you through the planning process if you decide to go ahead. --David Wall
