With AWS IoT Device Management, you can securely add device attributes like device name, type and manufacturing year, certificates and access policies to the AWS IoT Registry in bulk, assign them to devices, and put large fleets of devices into service quickly.

AWS IoT Device Management lets you organize your devices into groups and manage access policies for these groups. This makes it easy to track, operate, and manage your devices according to business and security requirements, such as deploying a firmware update for all devices in a building or defining how devices communicate with each other. You can create a hierarchy for your groups such as grouping multiple sensors within a single vehicle and grouping multiple vehicles in a fleet. Then, your devices will inherit access policies based on the group hierarchy.
