NORTEL TPS 3D SENSOR AND DEFENSE CENTER INSTALLATION G UIDE RELEASE 4.7.0 PAGE 6Chapter 1: Before you begin• that use IPS to detect and prevent attacks on your network assetsdeployment issues, such as which network segments you want to monitorwith your 3D Sensors, and why• how you will physically connect the sensors to your network, taking intoaccount any special network configuration factors, such as firewallplacement, VPN deployments• whether you will use a Nortel Defense Center to aggregate and correlateRNA and intrusion eventsSee the following sections for more information.• “IPS installation considerations” on page 6• “RNA installation considerations” on page 7“• “RUA installation considerations” on page 7• “Typical 3D Sensor deployments” on page 8• “Other deployment options” on page 15• “Understanding detection engines and interface sets” on page 18• “Connecting sensors to your network” on page 20• “Using a Nortel Defense Center” on page 23IPS installation considerationsIPS is the intrusion prevention and detection component of the Nortel TPS 3DSystem. Before you install a 3D Sensor with IPS, you should consider how yournetwork is configured and how you want to deploy the various components of theNortel TPS 3D System within it.Every network architecture is different, and every enterprise has different securityneeds. This section lists some of the factors you should consider as you formulateyour deployment plans and includes a description of how the Nortel TPS 3DSystem can help you meet common network security goals.Your deployment decisions for 3D Sensors with IPS will be based on a variety offactors. Answering these questions can help you understand the vulnerable areasof your network and clarify your intrusion detection and prevention needs.• Will you be deploying your 3D Sensor with passive or inline interface sets?Does your 3D Sensor support multiple detection engines with a mix ofinterface sets, some passive and others inline? See “Understandingdetection engines and interface sets” on page 18 for more information aboutdetection engines and interface sets and how they influence your sensordeployment.• How will you connect the 3D Sensors to the network? Hubs? Taps?Spanning ports on switches? See “Connecting sensors to your network” onpage 20 for more information about methods for connecting the sensinginterfaces on your sensor to your network.
