Ensuring security of systems based on supervisory control and data acquisition (SCADA) is a major challenge. In this paper we analyze the effect of integrity attacks on control systems and provide countermeasure capable of exposing such attacks. To validate the results, we apply our findings to an industrial control problem concerning a chemical plant and(More)
Network security is a major issue affecting SCADA systems designed and deployed in the last decade. Simulation of network attacks on a SCADA system presents certain challenges, since even a simple SCADA system is composed of models in several domains and simulation environments. Here we demonstrate the use of C2WindTunnel to simulate a plant and its(More)
A SCADA system employing the distributed networks of sensors and actuators that interact with the physical environment is vulnerable to attacks that target the interface between the cyber and physical subsystems. An attack that hijacks the sensors in an attempt to provide false readings to the controller (for example, the Stuxnet worm that targeted Iran’s(More)
Security is a major issue affecting SCADA systems, designed and deployed in the last decade. Simulation of network attacks on a SCADA system presents certain challenges, since even a simple SCADA system is composed of models in heterogenous domains and simulation environments. Here, we simulate a chemical plant and its controller, communicating through an(More)
