Kaspersky Security Center

Using the "Do not disconnect from the Administration Server" option to provide continuous connectivity between a managed device and the Administration Server

If you do not use push servers, Kaspersky Security Center does not provide continuous connectivity between managed devices and the Administration Server. Network Agents on managed devices periodically establish connections and synchronize with the Administration Server. The interval between those synchronization sessions is defined in a policy of Network Agent. If an early synchronization is required, the Administration Server (or a distribution point, if it is in use) sends a signed network packet over an IPv4 or IPv6 network to the UDP port of the Network Agent. By default, the port number is 15000. If no connection through UDP is possible between the Administration Server and a managed device, synchronization will run at the next regular connection of Network Agent to the Administration Server within the synchronization interval.

Some operations cannot be performed without an early connection between Network Agent and the Administration Server, such as running and stopping local tasks, receiving statistics for a managed application, or creating a tunnel. To resolve this issue, if you are not using push servers, you can use the Do not disconnect from the Administration Server option to make sure that there is continuous connectivity between a managed device and the Administration Server.

To provide continuous connectivity between a managed device and the Administration Server:

  1. Do one of the following:
    • If the managed device accesses the Administration Server directly (that is, not via a distribution point):
      1. In the console tree, select the Managed devices folder.
      2. In the workspace of the folder, select the managed device with which you want to provide continuous connectivity.
      3. In the context menu of the device, select Properties.

        The properties window of the selected device opens.

    • If the managed device accesses the Administration Server through a distribution point running in gateway mode, not directly:
      1. In the console tree, select the Administration Server node.
      2. In the context menu of the node, select Properties.
      3. In the Administration Server properties window that opens, select the Distribution points section.
      4. In the list, select the necessary distribution point, and then click Properties.

        The properties window of the distribution point opens.

  2. In the General section of the displayed window, select the Do not disconnect from the Administration Server option.

Continuous connectivity is established between the managed device and the Administration Server.

The maximum total number of devices with the Do not disconnect from the Administration Server option selected is 300.
