Abstract
A server holds correspondence information in which a device identifier of a device for which an authentication process is successful and area network information concerning an area network including a controller are associated with each other. In the case where the authentication process is successful, the device holds area network information concerning an area network including a controller for which authentication is successful. In response to a connection request from a new device, the server checks whether an identifier of the new device is registered in the correspondence information. If the identifier is registered, the server determines whether the area network information associated with the identifier matches the area network information held by the new device. If the pieces of information do not match, the server detects the new device as an unauthorized device.
