Preserving the availability and integrity of networked computing systems in the face of fast-spreading intrusions requires advances not only in detection algorithms, but also in automated response techniques. In this paper, we propose a new approach to automated response called the Response and Recovery Engine (RRE). Our engine employs a game-theoretic(More)
Recently, there has been an increased focus and a sense of urgency in developing standards for Power Grid systems centered on the need for interoperability. Given the threat against these systems an important goal is the development of effective cyber security standards. However , past experience shows that security protocols are prone to design errors.(More)
The Virtual Power System Testbed (VPST) at University of Illinois at Urbana-Champaign is part of the Trustworthy Cyber Infrastructure for the Power Grid (TCIP) and is maintained by members of the Information Trust Institute (ITI). VPST is designed to be integrated with other testbeds across the country to explore performance and security of Supervisory(More)
—Sound cyber security testing is a critical challenge, in particular for large and complex systems such as the smart grid. In this paper, we explore the need for, and specific issues involved in, security testing for smart grid components and standards and how testbeds play a critical role in that environment. We present three main problems; the need for a(More)
The Smart Grid control systems need to be protected from internal attacks within the perimeter. In Smart Grid, the Intelligent Electronic Devices (IEDs) are resource-constrained devices that do not have the ability to provide security analysis and protection by themselves. And the commonly used industrial control system protocols offer little security(More)
(USC-ISI) consortium is working toward providing tools and expertise to enable collaborative research to improve security and resiliency of cyber physical systems. In this extended abstract we discuss the challenges and the solution space. We demonstrate the feasibility of some of the proposed components through a wide-area situational awareness experiment(More)
