Abstract

A method (300) for detecting an intrusion into an industrial control system including an industrial control program and an industrial control device (510), which is configured for a cycle-based execution of the industrial control program, wherein the method (300, 5112) includes: providing (5114) a trained data set, which is trained based on multiple previous records including an identifier indicative of a respective process and a duration of the process, wherein the data set is configured to output an expected duration in response to a query including the identifier; performing (S200) for each process in each cycle (500): recording (S214) an identifier; recording (S212, 5228) a duration of the execution of the process; querying (S238) the recorded identifier to the data set; receiving (S240) from the data set an expected duration; and detecting (S244) an intrusion based on comparing (S242) the recorded duration with the expected duration.
