In order to keep the level of security as high as possible, you need to build a comprehensive monitoring and alerting solution around your devices.
Az the first step, you already enabled IoT Defender for your IoT hubs.
Now you want to configure an alerting system customized to the type and behavior of your devices.
Most of the devices connect to the IoT hub directly but some legacy devices use edge gateways to send data to the hub.
How do you customize the alerting system to the types of devices?

A. B. C. D.Correct Answer: C.
Option A is incorrect because if you want to customize the alerts by the type of device, the “SecurityGroup” tag with the name of the corresponding security group should be added to all device twins, not only for the edges.
Option B is incorrect because while the security module twin holds all the information relevant to device security for each of your devices, to create custom alerts for device categories, the “SecurityGroup” tag should be used in the device twins.
Option C is CORRECT because the “SecurityGroup” tag is designed for defining logical groups of devices, and managing their security state in a centralized way.
Its place is in the device twin.
When created, each device belongs to the security group “default”.
Option D is incorrect because if you need to customize the alerts by the type of devices, you should use group names different from “default” in the device twins.
References:
To customize the alerting system to the types of devices in the IoT solution, you need to add a tag called "SecurityGroup" to the device twins. This tag will allow you to group devices based on their type and behavior and set up custom alerts for each group.
The answer options provided are:
A. Add the {"SecurityGroup": "default"} tag to twins of the edge devices B. Add the "SecurityGroup": "secGrp01" tag to the azureiotsecurity module twin C. Add the "SecurityGroup": "secGrp01" tag to twins of each device D. Add the {"SecurityGroup": "default"} tag to twins of each device.
Option A is incorrect because it only adds the tag to the edge devices, and not all the devices in the solution.
Option B is also incorrect because it adds the tag to the azureiotsecurity module twin, which is not relevant to customizing the alerting system for device types.
Option C is correct because it adds the "SecurityGroup" tag to each device twin, allowing you to group devices based on their behavior and set up custom alerts for each group.
Option D is incorrect because it adds the tag to all devices in the solution, but does not allow for custom grouping and alerting based on device behavior.
Therefore, the correct answer is C - Add the "SecurityGroup": "secGrp01" tag to twins of each device.
