1. A determination device comprising at least one processor, wherein:
the at least one processor determines whether a signal flowing on a communication network in a moving object is abnormal;
the at least one processor determines when the at least one processor determines that the signal flowing on the communication network is abnormal, whether a communication device which is a transmission source of the abnormal signal is normal; and
the at least one processor determines that an attack on the communication network has occurred, when the at least one processor determines that the signal flowing on the communication network is abnormal, and the at least one processor determines that the communication device which is the transmission source of the abnormal signal is normal, wherein
the at least one processor determines whether the signal flowing on the communication network is abnormal for each type of signal, and
the at least one processor performs in a case where the at least one processor determines that a first type of signal flowing on the communication network is abnormal, when the at least one processor determines that a second type of signal, which has a different type from the first type of signal and is transmitted to the communication network from a communication device that is a transmission source of the first type of signal, is not abnormal, a determination that the communication device which is the transmission source is normal.
