A security device connected to a plurality of networks in a vehicle is provided. The security device determines, with regard to a frame received from a first network, whether to transmit a determination request for the frame outside the vehicle. The security device transmits the determination request outside the vehicle in a case where it is determined to transmit the determination request outside the vehicle, transmits, before obtaining a determination result from outside the vehicle in accordance with the determination request, the frame to a second network, and then obtains determination results from outside the vehicle in accordance with the determination request.
