Abstract
A computer-implemented method includes obtaining, by one or more processing devices, a wireless message of an Internet of Things (IoT) device by monitoring a wireless signal sent by the IoT device; determining, by the one or more processing devices, a target running feature of the IoT device based on the wireless message; comparing, by the one or more processing devices, the target running feature with a historical normal running feature of the IoT device; and determining, by the one or more processing devices, whether the IoT device runs abnormally based on the comparing of the target running feature with the historical normal running feature of the IoT device.
