Chapter 1: Before you begin
Deploying in Multi-Site environments
Many organizations want to extend intrusion detection across a geographically
disparate enterprise and then analyze all the IPS data from one location. The
Nortel 3D System supports this by offering the Defense Center, which aggregates
and correlates events from 3D Sensors deployed throughout the organization's
many locations. Unlike deploying multiple 3D Sensors and Defense Centers in the
same geographic location on the same network, when deploying 3D Sensors in
disparate geographic locations, you must take precautions to ensure the security
of the 3D Sensors and the data stream. To secure the data, you must isolate the
3D Sensors and Defense Center from unprotected networks. You can do this by
transmitting the data stream from the 3D Sensors over a VPN or with some other
secure tunneling protocol as shown in the following diagram.
