EFORE YOU BEGIN
IMPORTANT! Beginning with Release 4.7 software, 3D Sensors refer to both
Intrusion Sensors and RTI Sensors. A 3D Sensor is able to have Intrusion
Sensing (IPS/IDS) and/or RTI capabilities.
This guide describes how to install and set up the Nortel 3D Sensor. Depending
on which Nortel 3D System products you have licensed, a Nortel 3D Sensor can
include:
• IPS, the intrusion detection and prevention component
• RNA, the Real-time Network Awareness component
• RUA, the Real-time User Awareness component
• any two components, or all three
Each of the components is described in detail in the Nortel TPS 3D System User
Guide. You can install a 3D Sensor with the IPS component as a standalone
appliance, but if you want to use RNA or RUA, you must use the 3D Sensor with a
Defense Center. Note that some models of the 3D Sensor do not support every
combination of components. See
sets" on page 18 for more information.
Before you install a Nortel 3D Sensor, you should consider how your network is
configured and how you want to deploy the various components of the Nortel TPS
3D System within it.
This chapter describes some of the considerations for deploying a 3D Sensor,
including:
• the concept of the detection engine and the modes in which you can deploy
detection engines on the 3D Sensor: passive or inline
• your goals in deploying sensors that use RNA to perform network discovery
and vulnerability assessment, as well as your goals in deploying sensors
