This is one of the very first decisions that you need to make. Where you deploy your Sensors and which Sensor model to use depends on your network topology, the amount of traffic on the network, and your security goals, which ideally are based on your company's security requirements.
Determine where you will place the Sensors. This is an individual decision your company will need to make. Questions to ask yourself in making this decision are covered at a high level in the Pre-deployment Considerations section of this document. Some things to consider are what assets you want to protect, the configuration of your network, the location of your aggregation points, the type of traffic, how the traffic is routed, and so on.
Establish a naming convention for your Sensors. The Sensor name is used to identify the Sensor in the Manager interface, in certain reports, and in the alert data generated by the Sensor. Trellix recommends you to establish a naming convention that is easy to interpret by anyone working with the Trellix IPS deployment. After you name a Sensor, you cannot rename it without de-installing the Sensor-to-Manager communication. After renaming the Sensor, you must reinstall this communication.
