Distribution point

A distribution point is a device with Network Agent installed that is used for update distribution, remote installation of applications, and retrieval of information about networked devices. A distribution point can perform the following functions:

  • Distribute updates and installation packages to client devices within the group (including distribution through multicasting using UDP). Updates can be received from Kaspersky update servers through an update task created for the distribution point.

    Distribution point devices running macOS cannot download updates from Kaspersky update servers.

    If one or more devices running macOS are within the scope of the Download updates to the repositories of distribution points task, the task completes with the Failed status, even if it has successfully completed on all Windows devices.

  • Distribute policies and group tasks through multicasting using UDP.
  • Act as a gateway for connection to the Administration Server for devices in an administration group.

    If a direct connection between managed devices within the group and the Administration Server cannot be established, you can use the distribution point as connection gateway to the Administration Server for this group. In this case, managed devices connect to the connection gateway, which in turn connects to the Administration Server.

    The presence of a distribution point that functions as connection gateway does not block the option of a direct connection between managed devices and the Administration Server. If the connection gateway is not available, but direct connection with the Administration Server is technically possible, managed devices are connected to the Administration Server directly.

  • Poll the network to detect new devices and update information about existing ones.
  • Perform remote installation of third-party software and Kaspersky applications through Microsoft Windows tools, including installation on client devices without Network Agent.

    This feature enables you to remotely transfer Network Agent installation packages to client devices located on networks to which the Administration Server has no direct access.

  • Act as a proxy server participating in the Kaspersky Security Network.

    This feature is not supported by distribution point devices running Linux or macOS.

    You can enable KSN proxy server on the distribution point side to make the device act as a KSN proxy server. In this case, the KSN proxy service (ksnproxy) is run on the device.

Files are transmitted from the Administration Server to a distribution point over HTTP or, if SSL connection is enabled, over HTTPS. Using HTTP or HTTPS results in a higher level of performance, compared to SOAP, through reducing traffic.

Devices with Network Agent installed must be assigned distribution points manually according to administration groups. The full list of distribution points for specified administration groups is displayed in the report about the list of distribution points.

The scope of a distribution point is the administration group to which it has been assigned by the administrator, as well as its subgroups of all levels of embedding. However, the device acting as the distribution point may not be included in the administration group to which it has been assigned. If multiple distribution points have been assigned in the hierarchy of administration groups, Network Agent on the managed device connects to the nearest distribution point in the hierarchy.

A network location can also be the scope of distribution points. The network location is used for manual creation of a set of devices to which the distribution point will distribute updates. Network location can be determined only for devices running a Windows operating system.

Kaspersky Security Center Cloud Console assigns each Network Agent a unique IP multicast address that differs from every other address. This enables you to avoid network overload that might occur due to IP overlaps.

If two or more distribution points are assigned to a single network area or to a single administration group, one of them becomes the active distribution point, and the rest become standby distribution points. The active distribution point downloads updates and installation packages directly from the Administration Server, while standby distribution points receive updates from the active distribution point only. In this case, files are downloaded once from the Administration Server and then are distributed among distribution points. If the active distribution point becomes unavailable for any reason, one of the standby distribution points becomes active. The Administration Server automatically assigns a distribution point to act as standby.

The distribution point status (Active/Standby) is displayed with a check box in the klnagchk report.

A distribution point requires at least 4 GB of free disk space. If the free disk space of the distribution point is less than 2 GB, Kaspersky Security Center Cloud Console creates a security issue with the Warning importance level. The security issue will be published in the device properties, in the Security issues section.

Running remote installation tasks on a device assigned as distribution point requires additional free disk space. The volume of free disk space must exceed the total size of all installation packages to be installed.

Running any updating (patching) tasks and vulnerability fix tasks on a device assigned as distribution point requires additional free disk space. The volume of free disk space must be at least twice the total size of all patches to be installed.

Devices functioning as distribution points must be protected, including physical protection, against any unauthorized access.
