For the Kaspersky Security solution to function, constant interaction between the Protection Server and the Integration Server is required. To ensure this interaction, you need to configure the connection of the SVM from the Protection Server to the Integration Server.
If you want Light Agents to receive information about SVMs through the Integration Server, or if you want to protect the connection between the Protection Server and Light Agent, you must also configure the connection of Light Agents to the Integration Server.
Information about the loss and restoration of the connection of the Light Agent and SVM to the Integration Server can be saved as events in Kaspersky Security Center.
