Abstract
A traffic sensor includes processing circuitry configured to calculate a degree of spread of a range of normal communication indicated by a normal communication model for each of the normal communication model for detecting abnormal communication of an Internet of Things (IoT) device learned for each of the IoT device to be monitored, classify a normal communication model in which the degree of spread is less than a predetermined value as a normal communication model of an IoT device of a first model, and classify a normal communication model in which the degree of spread is equal to or greater than the predetermined value as a normal communication model of an IoT device of a second model, detect abnormal communication in the IoT device by using the normal communication model of the IoT device of the first model, and extract a feature amount.
