Installing a Server and external sensors

When installing a Server with external sensors, at least 2 and up to 33 computers can be used for installing application components. The Server is installed on one of the computers. The sensors that will receive data from computer networks are installed on the other computers.

To receive traffic from the industrial network, you must add monitoring points to computers:

• No more than 8 monitoring points on a sensor
• No more than 4 monitoring points on the Server
• No more than 32 monitoring points in the application

Monitoring points are added to their corresponding network interfaces of computers. A computer must have one network interface per each monitoring point.

Computers must also have separate network interfaces that will be used for the following purposes:

• Connection with the Server (on computers that perform sensor functions)
• Connection with other computers through the web interface
• Receipt of data from EPP applications
• Connection through connectors (on the computer that performs Server functions)

For these purposes, each computer can use either multiple separate network interfaces or one shared network interface. There must be no monitoring points on these network interfaces.

The figure below shows an example scenario for deploying a Server and three sensors. The network interfaces of computers that perform sensor functions are connected to the SPAN ports of network switches (SPAN ports and connections are marked in yellow) and receive a copy of traffic from their respective segments of the industrial network. The dedicated Kaspersky Industrial CyberSecurity network is designated by green lines.
