Deploying Azure Defender for IoT in mixed OT/IT environments involves planning network traffic mirroring, configuring on-prem OT sensors, and setting up micro agents for device-level monitoring. The Skill provides category-indexed architecture and deployment guidance to plan and deploy OT sensors, micro agents, and traffic mirroring across on-prem and cloud environments.

The best way to integrate IoT security alerts with a SIEM is by configuring Azure Defender for IoT forwarding rules to send detected OT threats to your centralized security information and event management system. The Skill provides integration guidance for connecting Azure Defender for IoT alerts with SIEM systems across on-prem and cloud environments.

Troubleshooting an OT sensor not seeing network traffic involves verifying the SPAN port or traffic mirroring configuration, validating the sensor network interfaces, and confirming the monitoring interface is receiving the expected OT protocol packets. The Skill provides category-indexed troubleshooting guidance for OT sensors, traffic mirroring, and configuration issues.

Azure Defender for IoT micro agents can be deployed on supported operating systems to provide behavioral threat detection, but legacy operational technology devices may lack the resource capacity or compatibility required for agent installation. The Skill provides category-indexed configuration guidance for micro agents across mixed OT/IT environments.

Recommended IoT security architecture design patterns for manufacturing involve deploying air-gapped OT sensors for passive traffic monitoring, configuring micro agents on critical endpoints, and routing aggregated telemetry to SIEM integrations for centralized alerting. The Skill provides category-indexed architecture and design guidance for securing OT/IoT environments.

Azure Defender for IoT requires traffic mirroring for OT monitoring because operational technology networks rely on proprietary protocols that cannot be actively scanned, so passive SPAN port mirroring is needed to safely analyze industrial control traffic without disrupting critical processes. The Skill provides architecture guidance for traffic mirroring and OT sensor configuration.
