6.1 Introduction

Smart cities integrate sensory, actuation, and intelligent system to achieve human‐centric socioeconomic goals. With multiple systems being integrated, we abstract a smart city as a system of cyber‐physical systems (CPS). With a “System of Systems” approach, we focus on the study of the CPS resilience in a smart city. Resilience describes the ability of the CPS to withstand and quickly recover from adverse conditions. Adverse condition could manifest as cyber and/or physical incidents that could lead to operational disruptions of a CPS. Improving the ability of critical CPS to recover quickly and efficiently from such incidents leads to a flourishing and more reliable smart city ecosystem.

The continuously evolving nature of advanced and complex threats targeting CPS systems is challenging existing approaches to cybersecurity detection, response, and recovery. This is motivating the investigation of new and innovative cyber resilience approaches at different levels of emerging CPS within a smart city such as the smart grid. The complexity of interconnected CPS systems in a smart city offers a multitude of challenges and opportunities when addressing ...
