Abnormal Control Data Detection System Using Swiching Device

摘要

An abnormal control data detection system using a switching device capable of duplicating control data using a switching device is controlled by the control data, at least one input port to which a control terminal generating control data is connected and the control data is inputted. a switching device comprising at least one output port to which a control device is connected to output the control data, and a destination port to which control data to be output to the control device is copied and output; and generating a normal control data cluster or normal control data security rule based on the control data connected to the destination port and output from the destination port, and when the target control data is received from the control terminal, the normal control data cluster or normal control data and a detection server that determines whether the target control data is abnormal by using a security rule.
