The present invention relates to the technical field of industrial networks and information security, and in particular to an industrial control system and a network security monitoring method therefor, for effectively monitoring the network security of an industrial control system. The method comprises: selecting at least one first data source related to an industrial control system and acquiring first data therefrom; counting time-varying features of the first data to serve as a behavior model for the industrial control system; acquiring second data from some or all of the at least one first data source; and determining whether the second data has the features described by the behavior model, and if so, determining that the industrial control system exhibits normal behavior, and if not, determining that the industrial control system exhibits abnormal behavior. In consideration of the certainty of the behavior of the industrial control system, a system behavior model is obtained by means of counting. A judgement regarding an abnormal system behavior is made based on the relatively determined behavior model, so that the obtained determination result is more accurate.
