Title: Cyber-Physical Security of the Smart Grid
Abstract: The scale and complexity of the smart grid, along with its increased connectivity and automation, make the task of its cyber protection challenging. Recently, smart grid researchers and standards bodies have begun to develop technological requirements and potential solutions for protecting cyber infrastructure. However, grid protection remains daunting to asset owners because of resources limitations. Important questions arise when identifying priorities for design and protection: Which cyber components, if compromised, can lead to significant power delivery disruption? What grid topologies are inherently robust to classes of cyber-attack? Is the additional information available through advanced information technology worth the increased security risk? We assert that a key research challenge in addressing these fundamental questions lies in the effective understanding of the cyber-physical synergy of the smart grid. This gives rise to the problem of cyber-physical system security. In this talk, we introduce this emerging problem in the context of the smart grid and present dynamical systems-based frameworks for modeling cyber-physical interactions. We demonstrate how our approaches enable the identification of emergent vulnerabilities and the evaluation of the relative impacts of communication failure on the flow of electricity. The overall framework facilitates more comprehensive risk analysis and guidelines for resilient smart grid development.
