Microsoft Sentinel incidents for Defender for IoTĪfter you've configured the Defender for IoT data connector and have IoT/OT alert data streaming to Microsoft Sentinel, use one of the following methods to create incidents based on those alerts: Method If you integrate Defender for IoT with Microsoft Sentinel, we recommend that you manage your alert statuses together with the related incidents in Microsoft Sentinel. OT teams either suppress the alert or learn it for next time, as neededĪfter the threat is mitigated, SOC teams close the incidentĪfter the threat is mitigated, OT teams close the alertĪlert status changes are synchronized from Microsoft Sentinel to Defender for IoT only, and not from Defender for IoT to Microsoft Sentinel. SOC teams respond with OT playbooks and notebooks SOC teams move the incident to Active and start investigating, using network connections and events, workbooks, and the OT device entity pageĪlerts are moved to Active, and OT teams investigate using PCAP data, detailed reports, and other device details SOC teams map business impact, including data about the site, line, compromised assets, and OT owners High confidence OT alerts, powered by Defender for IoT's Section 52 security research group, are triggered based on data ingested to Defender for IoT.Īnalytics rules automatically open incidents only for relevant use cases, avoiding OT alert fatigue The following table shows how both the OT team, on the Defender for IoT side, and the SOC team, on the Microsoft Sentinel side, can detect and respond to threats fast across the entire attack timeline. Then, also install the Microsoft Defender for IoT solution the extra value of IoT/OT-specific analytics rules, workbooks, and SOAR playbooks, as well as incident mappings to MITRE ATT&CK for ICS techniques. Install the Defender for IoT data connector alone to stream your OT network alerts to Microsoft Sentinel. In Microsoft Sentinel, the Defender for IoT data connector and solution brings out-of-the-box security content to SOC teams, helping them to view, analyze and respond to OT security alerts, and understand the generated incidents in the broader organizational threat contents. SOC teams can use the integration between Microsoft Defender for Iot and Microsoft Sentinel to collect data across networks, detect and investigate threats, and respond to incidents. Microsoft Sentinel is a scalable cloud service for security information event management (SIEM) security orchestration automated response (SOAR). Integrate Defender for IoT and Microsoft Sentinel However, without OT telemetry, context and integration with existing SOC tools and workflows, OT security and operational threats may be handled incorrectly, or even go unnoticed. You'll need to evaluate and link information across data sources for OT networks, and integrations with existing SOC solutions may be costly. Limited technology and tools, such as lack of visibility or automated security remediation for OT networks. Siloed or inefficient communication and processes between OT and SOC organizations. This often translates into vague or minimized understanding of OT incidents and their business impact. Lack of OT expertise and knowledge within current SOC teams regarding OT alerts, industrial equipment, protocols, and network behavior. Together with the new responsibilities, SOC teams deal with new challenges, including: As more business-critical industries transform their OT systems to digital IT infrastructures, security operation center (SOC) teams and chief information security officers (CISOs) are increasingly responsible for threats from OT networks. ![]()
