12.1 Introduction

Cyber‐physical systems (CPSs) are engineered systems built from the integration of computation, networking, and physical processes. Researchers often generalize “CPS” as an integrated system of cyber and physical systems, where embedded computers and networks are used to compute, communicate, and control the physical processes (Baheti and Gill, 2011; Wang, 2010). Advances in CPS make them crucial in most of the industries, e.g. energy delivery systems (EDS) (McMillin et al., 2007), healthcare systems (Cheng, 2008), transportation systems (Xiong et al., 2015), or smart systems (smart grid, smart homes, smart cities, etc.) (Amin, 2015; Yu and Xue, 2016). The advancements in engineering processes also bring the risk of cyberattacks because of the integration of the cyber and physical domains – in other terms information technology (IT) and operational technology (OT) domain. Therefore, the cyber resiliency of such systems considering the vulnerabilities of different components within the networked system is an integral part of CPS security analysis.
