Abstract: A signal determination device includes an identification unit which identifies a reference signal that serves as a reference to identify an abnormal signal among a plurality of signals detected in the communication network, a time interval estimation unit which estimates a time interval of signals that are to be input in series to the communication network based on detection timing of the plurality of signals detected in the communication network, a timing estimation unit which estimates timing at which a plurality of signals is to be detected in the communication network after the reference signal, and a determination unit which determines whether each of the plurality of signals detected in the communication network after the reference signal is a normal signal based on the timing estimated by the timing estimation unit and detection timing of the plurality of signals detected in the communication network after the reference signal.
