Abstract
A creation device includes processing circuitry configured to collect pieces of information about IoT (Internet of Things) apparatuses connected to IoT gateways, and white lists stored in the IoT gateways, the white lists specifying content of communication allowed for each of the IoT apparatuses, calculate a feature value showing communication features of IoT apparatuses for each of the IoT gateways, and degrees of similarity in the feature value among the IoT gateways, based on the collected pieces of information about the IoT apparatuses, and extract, if any of the calculated similarity degrees is equal to or above a predetermined threshold, pieces of white list information about IoT apparatuses to mutually complement white lists stored in IoT gateways, from pieces of white list information about IoT apparatuses included in the white lists.
