Device discovery

ID 3884

This section describes the types of device discovery available in Kaspersky Security Center and provides information using each type.

The Administration Server receives information about the structure of the network and devices on this network through regular polling. The information is recorded to the Administration Server database. Administration Server can use the following types of polling:

  • Windows network polling. The Administration Server can perform two kinds of Windows network poll: quick and full. During a quick poll, the Administration Server only retrieves information from the list of the NetBIOS names of devices in all network domains and workgroups. During a full poll, more information is requested from each client device, such as operating system name, IP address, DNS name, and NetBIOS name. By default, both quick poll and full poll are enabled. Windows network polling may fail to discover devices, for example, if the ports UDP 137, UDP 138, TCP 139 are closed on the router or by the firewall.
  • Active Directory polling. The Administration Server retrieves information about the Active Directory unit structure and about DNS names of the devices from Active Directory groups. By default, this type of polling is enabled. We recommend that you use Active Directory polling if you use Active Directory; otherwise, the Administration Server does not discover any devices. If you use Active Directory but some of the networked devices are not listed as members, these devices cannot be discovered by Active Directory polling.
  • IP range polling. The Administration Server polls the specified IP ranges using ICMP packets or the NBNS protocol and compiles a complete set of data on devices within those IP ranges. By default, this type of polling is disabled. It is not recommended to use this type of polling if you use Windows network polling and/or Active Directory polling.
  • Zeroconf polling. A distribution point that polls the IPv6 network by using zero-configuration networking (also referred to as Zeroconf). By default, this type of polling is disabled. You can use Zeroconf polling if the distribution point runs Linux.

If you set up and enabled device moving rules, the newly discovered devices are automatically included in the Managed devices group. If no moving rules have been enabled, the newly discovered devices are automatically included in the Unassigned devices group.

You can modify device discovery settings for each type. For example, you may want to modify the polling schedule or to set whether to poll the entire Active Directory forest or only a specific domain.

Before you start network polling, make sure that the SMB protocol is enabled. Otherwise, Kaspersky Security Center cannot discover devices in the polled network. To enable the SMB protocol, follow the instructions for your operating system.
