CMDB classes targeted in the Service Graph Connector for Microsoft Defender for IoT (Azure)
When you complete the guided setup, you can configure the integration to periodically pull data from a Service Graph Connector for Microsoft Defender for IoT (Azure) (Azure) project. The data is saved in tables that extend from the Configuration item [cmdb_ci] table.
Viewing class mappings
You can view the available class mappings for the Service Graph Connector for Microsoft Defender for IoT (Azure) by navigating to All > Service Graph for MSFT D4IoT (Azure) > Class Mappings. In the class mappings table, you can view the following attributes.
| Field | Description |
|---|
| Source Class | The device type from the source system \(Azure\). |
| Target CMDB class | The expected ServiceNow class for the CI. |
| OT Device type | The category type that the OT device is classified as. The device type is also the function that the device plays on the OT network. For example:An IT device, such as a server, can be converted to an OT device, and the function it plays on the network is an HMI. Therefore, its class is server and its device type is HMI. Note: In some cases, there are OT devices with no OT function or OT devices where the device type is unknown. For OT devices with no OT function, select No OT Function. For OT devices where the device type is unknown, select Unknown. |
| Allow OS classification | When set to True, if an operating system is found on the CI, the target is switched away from the target CMDB class to a ServiceNow class that matches its OS. |
| Active | When checked, the class mapping is set to Active. |
