You must perform device discovery before installation of the security applications. When all networked devices are discovered, you can receive information about them and manage them through policies. Regular network polls are needed to discover if there are any new devices and whether previously discovered devices are still on the network.
Discovery of networked devices proceeds in stages:
Decide which type(s) of discovery you want to use regularly. Make sure that this type is enabled and that the poll schedule meets the needs of your organization. When configuring the poll schedule, use the recommendations for network polling frequency.
If new devices appear on your network, they are discovered during regular polls and are automatically included in the Unassigned devices group. If you want, you can set up the rules for automatically moving these devices to the Managed devices group. You can also establish retention rules.
If you skip this rule-setting stage, all the newly discovered devices go to the Unassigned devices group and stay there. If you want, you can move these devices to the Managed devices group manually. If you move the devices to the Managed devices group manually, you can analyze information about each device and decide whether you want to move it to an administration group, and, if so, to which group.
Completion of the scenario yields the following:
