We live in an era in which our physical and personal environments are becoming increasingly smarter as they are immersed in sensing, networking, computing and communication capabilities. Indeed our daily lives depend on various cyber-physical infrastructures such as smart buildings, energy and utility networks, transportation and healthcare delivery systems, supply chain management, and so on. Additionally, the availability of rich mobile devices like smartphones and wireless sensors have empowered humans as an integral part of such systems. This synergy has led to what is called cyber-physical-social convergence exhibiting complex interactions, interdependencies and adaptations between devices, machines, systems/environments, and users with their social behavior and dynamics. In such a connected world, almost everything can potentially act as information source, analyzer, and decision maker. However, due to the scale, complexity and resource limitations, cyber-physical-social infrastructures are vulnerable to failures and security threats. This talk will discuss emerging research challenges in securing such infrastructures and propose novel frameworks for situation-aware detection and mitigation of attacks as well as recovery techniques. The proposed solutions will utilize sensor based monitoring and information fusion techniques based on a rich set of theoretical and practical design principles, such as game theory, trust model, information theory, epidemic theory, and statistical learning. The talk will be concluded with open research issues and challenges.
