Will ownership of the device need to be managed or transferred in a secure manner?
This penultimate blog in the IoT Security principles series, addresses transfer of ownership and how to manage that in a secure manner. Many IoT devices will change ownership at some point in their lifetime. To preserve the security of the device and data throughout its lifecycle, developers should:
- Provide a secure method to transfer ownership of the device to another user.
- This will allow both the old and new users to verify that the transfer of ownership has succeeded and that any sensitive data will be handled appropriately after handover.
- Be clear which system components (devices, data, network etc.) are owned by the user.
- Users or managers can clearly identify what their responsibilities are for ownership transfer. This will minimise the risk of security issues arising through misunderstandings of responsibilities.
- Ensure that change of ownership does not impact security updates.
- Critical security updates must continue to be supplied, regardless of who now owns the device.
The final part of the series covers IoT security principles for data audit in enterprises.
