Rok: 1998
Hodnocení: AnotaceHistorically, only large companies could afford secure networks, which they created from expensive leased lines. Smaller businesses had to make do with the relatively untrusted Internet. Now, 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 (VPN): 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. 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 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 and an expanded description of the IPSec standard, for which several vendors have announced support. Dostupné zdroje
