The purpose of the present invention is to provide an anomaly assessment device, etc., whereby it is possible to improve user convenience. In an anomaly assessment device 20, an acquisition unit 21 acquires event information which is transmitted from a device to be monitored 10. An identification unit 24 identifies a trend state which is associated with the event information which has been acquired by the acquisition unit 21. A storage unit 23 stores correspondences between device types and trend state candidate groups in stable states of devices of said types. An assessment unit 25 assesses whether the device to be monitored 10 is in a normal or an anomalous state on the basis of the trend state candidate group which is associated with the type of the device to be monitored 10 in the correspondences which are stored in the storage unit 23 and of the trend state which has been identified by the identification unit 24 using the event information.
