摘要
An attack/abnormality detection device includes: a command extraction unit configured to extract elements having the same command destination as a command destination of an additionally received actual manufacturing command from among each of a set of normal manufacturing commands and a set of actual manufacturing commands, which contain information on a command destination and an arrival order, and are stored in a command storage region; and a detection unit configured to detect an attack or an abnormality by comparing details of the commands with each other for each arrival order of both extracted elements.
