“…The testbed consists of four parts: (1) a commercial EMS is used in the SCADA system network; (2) IEC 61850 communication formed the SCN in simulated substations; (3) a power system simulation tool (i.e., DIgSILENT) is used to simulate a power system; and (4) the Object Linking and Embedding for Process Control (OPC) communication protocol bridges the physical and cyber domains [62].…”

Abstract:As part of the smart grid development, more and more technologies are developed and deployed on the power grid to enhance the system reliability. A primary purpose of the smart grid is to significantly increase the capability of computer-based remote control and automation. As a result, the level of connectivity has become much higher, and cyber security also becomes a potential threat to the cyber-physical systems (CPSs). In this paper, a survey of the state-of-the-art is conducted on the cyber security of the power grid concerning issues of: (1) the structure of CPSs in a smart grid; (2) cyber vulnerability assessment; (3) cyber protection systems; and (4) testbeds of a CPS. At Washington State University (WSU), the Smart City Testbed (SCT) has been developed to provide a platform to test, analyze and validate defense mechanisms against potential cyber intrusions. A test case is provided in this paper to demonstrate how a testbed helps the study of cyber security and the anomaly detection system (ADS) for substations.

Supervisory Control and Data Acquisition (SCADA) systems are traditionally proprietary and well protected. Due to increasing use of commercial/open source technology and communication protocols, there are growing concerns about the associated security threats. SCADA networks are usually employed in critical infrastructure, therefore, not much technical data of the actual systems is accessible to the research community.Most of the researchers simulate the SCADA functioning through development of testbed. Such projects are usually expensive and requiring financial sponsorship. In this paper we present a simple, inexpensive and flexible approach to develop a SCADA testbed utilizing TrueTime, a MATLAB/ Simulink based tool. The paper describes TrueTime simulation blocks, our control system, simulation of Denial of Service (DoS) attack and its effects. The main aim was to assess the effectiveness and suitability of TrueTime for the intended use in the development of a larger scale SCADA testbed. The results shown reflect that TrueTime can be effectively used for the purpose of SCADA network simulations and collection of necessary data for security analysis.

Cybersecurity issues have raised concerns as potential loopholes exist in the Supervisory Control And Data Acquisition (SCADA) system when the system architecture moved from a proprietary to an open system. As a result of the interdependency between the power grids and SCADA communication networks, it is important to further strengthen the defense of cyber networks against malicious intrusions. The focus of this research is to model and evaluate a novel cybersecurity protection scheme using network firewall technology operated at the application layer to enhance the information protection in SCADA networks. A quantitative analysis is performed based on the attack and defense simulations on the SCADA cybersecurity testbed available at UCD. The preliminary test results elucidate the effectiveness of the proposed scheme and demonstrate the feasibility of the proposed scheme for enhancing information security of the substations.
