Defender-IoT-micro-agent for Eclipse ThreadX architecture

The Defender-IoT-micro-agent for Eclipse ThreadX is initialized by the Azure IoT middleware platform and uses IoT Hub clients to send security telemetry to the Hub.

Micro agent state diagram and information flow.

The Defender-IoT-micro-agent for Eclipse ThreadX monitors the following device activity and information using three collectors:

  • Device network activity TCP, UDP, and ICM
  • System information as Threadx and NetX Duo versions
  • Heartbeat events

Each collector is linked to a priority group and each priority group has its own interval with possible values of Low, Medium, and High. The intervals affect the time interval in which the data is collected and sent.

Each time interval is configurable and the IoT connectors can be enabled and disabled in order to further customize your solution.

Supported security alerts and recommendations

The Defender-IoT-micro-agent for Eclipse ThreadX supports specific security alerts and recommendations. Make sure to review and customize the relevant alert and recommendation values for your service after completing the initial configuration.
