    Key Features

    • Supported Versions: Compatible with Microsoft Defender for IoT sensor versions 22.2.3.22 and 22.2.5.9.
    • Guided Setup: Provides an organized sequence of configuration tasks within ServiceNow to simplify integration setup.
    • CMDB Integrations Dashboard: Available through the Integration Commons for CMDB app, this dashboard offers monitoring of integration status, processing results, and errors with filtering options by integration and time period.
    • Data Mapping and Transformation: Uses the Robust Transform Engine (RTE) to map and transform Microsoft Defender for IoT data into ServiceNow CMDB classes, and the Identification and Reconciliation Engine (IRE) to insert data accurately.
    • Data Sources and Staging: Imports device and sensor data into specific staging tables before populating a wide range of CMDB target tables relevant to OT and IT infrastructure, such as servers, sensors, PLCs, and network devices.
    • Standard Mode Discovery: Supports importing OT devices discovered in Microsoft Defender for IoT using this mode.
    • Sensor Validation: Validates Network Intrusion Detection System (NIDS) sensors after import, ensuring only sensors not in learning mode are eligible for device import.
    • Connection Management: Access connection details centrally via the Common Connection Framework (CCF) within the Integration Commons for CMDB app.

    Practical Use and Benefits

    By implementing this connector, ServiceNow customers can automate the flow of OT device and sensor data from Microsoft Defender for IoT (Azure) into their CMDB, ensuring up-to-date and accurate configuration item data. This facilitates improved operational technology asset management, enhances security posture by validating sensor readiness, and provides visibility into integration performance through dedicated dashboards. The solution supports periodic data synchronization and targets a comprehensive set of CMDB classes, enabling detailed asset classification and attribute mapping tailored to OT environments.

    Next Steps for Customers

    • Use the guided setup in ServiceNow to configure the connector and start importing OT devices and sensors.
    • Monitor integration status and troubleshoot any issues using the CMDB Integrations Dashboard.
    • Validate imported NIDS sensors to ensure readiness for device import.
    • Review and understand the CMDB classes targeted by the connector to align with your asset management strategy.
    • Schedule periodic data pulls to maintain current and comprehensive OT device records in your CMDB.

    Integrate Microsoft Defender for IoT with the ServiceNow® Operational Technology Manager application to automate import of OT devices and sensor appliances.

    CMDB integrations dashboard

    The Integration Commons for CMDB store app provides a dashboard with a central view of the status, processing results, and processing errors of all installed integrations. You can see metrics for all integration runs. You can filter the view to a specific CMDB integration, a specific time duration, or a specific integration run. For more details about monitoring integrations in the CMDB Integrations Dashboard, see Integration Commons for CMDB.

    Data mapping

    Data from the Microsoft Defender for IoT (Azure) data sources is mapped and transformed into the ServiceNow CMDB Configuration Item (CI) class definitions using the Robust Transform Engine (RTE). Data is inserted into the ServiceNow CMDB using the Identification and Reconciliation Engine (IRE).

    When you complete the setup, you can configure the integration to periodically pull data from the Microsoft Defender for IoT (Azure) application.

    The following table lists the data sources included for a Microsoft Defender for IoT (Azure) project and the corresponding staging tables where the imported data is loaded.
