DETECTION OF MIS-CONFIGURATION AND HOSTILE ATTACKS IN INDUSTRIAL CONTROL NETWORKS USING ACTIVE QUERYING

摘要

A method includes requesting a controller, which controls one or more field devices in an industrial control network, to report code currently used by the controller for controlling the field devices. The code reported by the controller is compared with a stored baseline version of the code, and a notification is issued upon detecting a discrepancy between the code reported by the controller and the baseline version.
