Obtain a GUID Device class definitions require a name and one or more globally unique identifiers (GUIDs). Some hardware devices install their own new device class. If a suitable device class does not exist on the predefined list, or is not created automatically when new hardware is installed, you can create a new device class in the DLP Policy Manager. To control the behavior of plug-and-play hardware devices that define their own device class, you must first add a new device class to the Managed status in the Device Classes list. A device class is defined by two properties: a name and a GUID. The name of a new device is displayed in the device manager, but the GUID is displayed only in the Windows Registry and there is no easy way to obtain it. To ease the retrieval of new device names and GUIDs, the Device Control client reports a New Device Class Found event to the DLP Incident Manager when a hardware device that does not belong to a recognized device class is plugged into the host computer. Task 1 In McAfee ePO, select (Menu | Data Protection | DLP Incident Manager | Incident List). 2 Click Edit next to the Filter drop-down list to edit the filter criteria. 3 In the Available Properties list (left pane), select Incident Type. 4 Verify that the Comparison drop-down list value is Equals. 5 From the Values drop-down list, select Device New Class Found.
6 Click Update Filter. The Incident List displays the new device classes found on all endpoint computers. 7 To view the name and GUID of a specific device, double-click the item to display the incident details.
Create a device class Create a device class if a suitable device class does not exist on the predefined list or is not created automatically when new hardware is installed.
Before you begin Obtain the device GUID before beginning this task.
