For example, such technology is usable in authenticating IoT devices to an IoT Hub. In one example of the technology, data field targets are received for an IoT device. The data field targets may include at least one device identity data field target and at least one telemetry data field target. Data field entries are received from the IoT device at a first time. The data field entries may include at least one device identity data field entry and at least one telemetry data field entry. A determination is made as to whether the data field entries match the corresponding data field targets for the IoT device. The IoT device is selectively allowed to connect to the IoT hub based on the determination.
