Historically, only large companies could afford secure networks, which they created from expensive leased lines. Smaller folks had to make do with the relatively untrusted Internet. Nowadays, even large companies have to go outside their private nets, because so many people telecommute or log in while they\`re on the road. How do you provide a low-cost, secure electronic network for your organization?
The solution is a virtual private network: a collection of technologies that creates secure connections or \`tunnels\` over regular Internet lines--connections that can be easily used by anybody logging in from anywhere. A number of products now exist to help you develop that solution.
This book tells you how to plan and build a VPN. It starts with general concerns like costs, configuration, and how a VPN fits in with other networking technologies like firewalls. It continues with detailed descriptions of how to install and use VPN technologies that are available for Windows NT and Unix, such as PPTP and L2TP, Altavista Tunnel, Cisco PIX, and the secure shell (SSH).
New features in the second edition include SSH, which is a popular VPN solution for Unix systems, and an expanded description of the IPSec standard, for which several vendors have announced support.
Topics include:How the VPN compares to other available networking technologies
Point to Point Tunneling Protocol (PPTP) and L2TP
The Altavista Tunnel
The Cisco PIX Firewall
Secure Shell (SSH)
Maintenance and troubleshooting
Introduction to encryption, firewalls, the IPSec standard, and other technologies that let VPNs workAbout the Author
Paul Wolfe has done everything from driving M1A1 tanks in Desert Storm to slinging computer chips for Motorola. He now divides his time between his family and his job, as well as writing. He has written four books in the last two years, covering such topics as Windows NT Web servers, Internet commerce, VRML, and Virtual Private Networks. Paul is currently a team leader for system builds, hardware inventory, and ISDN deployment for Tivoli Systems, anIBM company. He dreams of restoring his 1986 Toyota Tercel to its former glory and racing it on the stock car circuit.
Charlie Scott is the senior vice president of OuterNet Connection Strategies, Inc., an Internet Service Provider and outsource company based in Austin, Texas, specializing in innovative and emergent technologies. At OuterNet, he helps create and implement new products for their network operations center and co-location facilities. While an undergraduate at the University of Texas at Austin, Charlie was a research assistant in a cognitive science lab, and planned on going to graduate school in that field. He was eventually able to get his B.A. in psychology. But he always enjoyed working with computers, and his exposure to the Internet at UT deviated him enough to abandon all plans for graduate school and start working with computer networks. The next few years saw him at Texas Instruments, IBM, and Wayne-Dresser before he helped found OuterNet. Charlie has also coauthored a half-dozen Internet-related books (many with Mike and Paul), on topics ranging from electronic commerce to CGI programming. When he finds spare time, Charlie likes to write (as of yet unpublished) fiction, read, and go to the gym. He also enjoys spending time with his wife, Mary, and their four beautiful felines.
