摘要：
A method and system for detection of intrusion in networked control systems, is provided. The method includes generating an operating model of a system being controlled. The operating model of the system comprises a relationship between a plurality of components in the system defined by a plurality of parameters. Further, the method includes calculating an estimated value of at least one parameter for at least one component in the system. The operating model is used to calculate the estimated value of the at least one parameter. Furthermore, the method includes measuring a latest value of at least one parameter at a predefined interval. The method also includes triggering an alert for intrusion for the at least one component based on an analysis of at least one of the latest value and the estimated value of at least one parameter.
