On Resilience and Defense against Attack-Induced Failures in Cyber-Physical Systems
Abstract
Short work statementThe proposed research will address the issues of~ characterizing attack-induced failures,~ modeling the system resilience using quantitative metrics, and~ developing cyber defense approaches against attackers with the intent to cause critical component-level or global failures in cyber-physical systems.ObjectiveThe proposed project aims to develop fundamental techniques that can clearly quantify the impact of cyber attacks as well as the effectiveness of the best defense strategy to improve the resilience against attack-induced failures.ApproachThe proposed research will address the problem of formally modeling the resilience and providing the cyber defense approaches against attackers with the intent to cause critical component or global system failures in a cyber-physical system.There are four major tasks in this proposed project.~ Develop time-varying multigraph model to characterize the coupled relationships between the physical power domain and the cyber domain, and between the connectivity of the power flow and the information flow.~ Design the optimal scheme of placing monitoring points (e.g. intrusion detection systems) for attack detection in a cyber-physical system. The method is aimed at understanding what is the minimum set of monitoring points can be placed at the component level that can accurately detect and intercept intrusion and attack-induced failure propagation.~ Define the resilience metrics for a cyber-physical system under attacks. These resilience metrics will be used to characterize how monitoring and control of critical components or global system states can be affected due to the attack-induced failures.~ Develop model and simulate a notional ship-board cyber-physical power system to measure and characterize both the impact of attacks and the effectiveness of defense. The models and techniques proposed in this project will be comprehensively validated and evaluated in simulations.Overall merits & ONR mission relevanceThe project is expected to provide fundamental techniques that can clearly quantify the impact of cyber-attacks as well as the effectiveness of the best defense strategy and to improve the resilience against attack-induced failures The techniques can also potentially provide guidelines to security deployment in ship-board cyber-physical power systems with future naval applications.
