A guide to delivering secure remote access to private enterprise networks.

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
