Virtual Private Networking : A Construction, Operation and Utilization Guide
暫譯: 虛擬私人網路：建構、操作與應用指南

Using the public communications infrastructure to connect remoteusers to an organization's network is a cost-effective and efficient way to provide communication and collaboration opportunities across large distances.  But how is private information kept private in a public network? And how may access be restricted to authorized individuals? Virtual Private networks (VPNs) hold the answer.

In Virtual Private Networking, Gil Held gives a detailed overview of the various VPN solutions available, how they are constructed, the rationale for their use, and which solutions satisfy which operational requirements.  Detailed information on specific products available from vendors such as Cisco and Checkpoint together with hands-on examples on how to configure client and server in a Microsoft Windows operating environment, make this a supremely practical tutorial for practicing network managers and administrators

Read on for:

• Information on appropria te authenication and encryption techniques
• A tutorial on TCP/IP focused specifically at creating and operating VPNs
• In-depth discussion on tunneling protocols PPTP and L2TP
• A comparison of commonly used security protocols IPSec and SSL
• The rationale for service provider-based VPNs and advice on service level agreement parameters to consider when using a VPN service provider

Concluding this book  is a comprehensive checklist of VPN features and operational techniques that may be used for 'build it yourself' applications as well as comparing the features and capabilities of third parties that provide VPN solutions.
