 - **Select tamper-proof hardware for assets**: Choose asset hardware with built-in mechanisms to detect physical tampering, such as the opening of the device cover or the removal of a part of the device. These tamper signals can be part of the data stream uploaded to the cloud, alerting operators to these events.
 
-- **Enable secure updates for asset firmware**: Use services like Device Update for IoT Hub for over-the-air updates for your assets. Build assets with secure paths for updates and cryptographic assurance of firmware versions to secure your assets during and after updates.
