Abstract
A determination apparatus according to a first embodiment collects information regarding communication performed by an IoT device. The determination apparatus extracts patterns used for detecting unauthorized communication performed by the IoT device from information that has been collected. Also, the determination apparatus approximates a change in the cumulative value of the number of patterns to a function that expresses a predetermined curve, thereby calculating the degree of convergence of the change. Also, the determination apparatus determines whether or not the degree of convergence is no less than a predetermined value.
