A security device connected to a bus in a vehicle includes a determination unit that determines, with regard to a frame received by a reception unit from the bus, whether or not predetermined conditions are satisfied to distinguish whether or not the frame may be an attack frame, an obtaining unit that effects control so that a determination request is transmitted to an external device outside of the vehicle in a case where the determination unit has determined that the predetermined conditions are satisfied, and obtains determination results transmitted from the external device in accordance to the determination request, and an output unit that outputs first presentation information in a case where the determination unit has determined that the predetermined conditions are satisfied, and outputs second presentation information in a case where the obtaining unit has obtained determination results from the external device.
