Functional Vulnerability Assessment of SCADA Network

The functional vulnerability of Supervisory Control and Data Acquisition (SCADA) Network is investigated in this paper. To describe the functional behavior of SCADA network, a simple dynamic model is used. Then, two SCADA networks with typical structure are reproduced according to the ones in the real world. The functional behaviors of two SCADA networks are investigated, which show that the star structure has better performance than the mesh structure. The response of SCADA network's behavior to the removal of edges is studied, which shows that the mesh network has better functional robustness than the star network.
