You have an Azure loT hub and an Azure virtual network.
You configure a private endpoint for the IoT hub.
You need to ensure that the loT hub can send data to downstream services
What should you create first?
You have an Azure IoT hub that uses a Device Provisioning Service instance.
You have 1,000 legacy IoT devices that only support MAC address or serial number identities. The device do NOT have a security feature that can be used to securely identify the device or a hardware security module (HSM).
You plan to deploy the devices to a secure environment.
You need to configure the Device Provisioning Service instance to ensure that all the devices are identified securely before they receive updates.
Which attestation mechanism should you choose?
A common problem with many legacy devices is that they often have an identity that is composed of a single piece of information. This identity information is usually a MAC address or a serial number. Legacy devices may not have a certificate, TPM, or any other security feature that can be used to securely identify the device. The Device Provisioning Service for IoT hub includes symmetric key attestation. Symmetric key attestation can be used to identify a device based off information like the MAC address or a serial number.
