Abstract: In an anomaly determination method for determining an anomaly in a received message, a plurality of messages which include messages that are periodic and each of which includes a first field having a fixed value and a second field having a variable value are each received as the received message, and one of a plurality of combinations to be used for determination each of which includes at least one of a plurality of anomaly determinations including an anomaly determination utilizing a reception timing based on the periodicity or the number of received messages, an anomaly determination utilizing the first field, and an anomaly determination utilizing the second field, is selected according to one or more criteria among available execution time of the anomaly determination method, a load amount, a data amount, and the number of messages.

Abstract: A monitoring device includes three or more monitors each monitoring, as a monitoring target, at least one of software and a communication log. The three or more monitors include a first monitor operating with a first execution privilege, a second monitor operating with a second execution privilege having a reliability level lower than the first execution privilege, and a third monitor operating with a third execution privilege having a reliability level that is the same as the second execution privilege or that is lower than the second execution privilege. The first monitor monitors software of the second monitor, and at least one of the first monitor or the second monitor monitors software of the third monitor.
