To correctly correlate the time of registration of events with the time when events occurred in the industrial network, time must be synchronized in the system. The time on nodes with Kaspersky Industrial CyberSecurity for Networks components installed must be synchronized with a common source of time used by industrial network devices.
When installing Kaspersky Industrial CyberSecurity for Networks 3.0, you can enable automatic time synchronization between the Server and nodes on which sensors are installed. In this case, the node with the Server installed will serve as the time source for nodes that have sensors installed.
It is recommended to use the software tools from the operating system of the computer performing Server functions to configure time synchronization between the application Server and the time source used by devices in the industrial network. For Server time synchronization, you can use the standard protocols known as Network Time Protocol (NTP) and Precision Time Protocol (PTP).
In Kaspersky Industrial CyberSecurity for Networks 3.0, the NTP protocol is used for automatic time synchronization between the Server and other nodes. In this case, you cannot configure synchronization with other time sources or use the PTP protocol on nodes that have sensors installed.
Kaspersky Industrial CyberSecurity for Networks 3.0.1 does not use the command for automatically enabling time synchronization between the Server and nodes that have sensors installed. For time synchronization, you have to configure the software tools of the operating system on all nodes that have application components installed.
For an example sequence of operations for configuring time synchronization, please refer to the Appendices.
