“…Other surveys have focused on defenses of different domains in cyber-physical systems, such as exploring vulnerabilities in smart grids [ 31 , 32 , 33 , 34 ], increasing attention to risks in medical devices [ 35 , 36 , 37 ], and addressing privacy and security issues in general systems [ 38 , 39 , 40 , 41 ]. Kayan et al [ 42 ] presented an interesting survey that reviewed the cybersecurity of overall industrial systems and infrastructures, such as Industrial Control Systems (ICS), Industrial cyber-physical systems (ICPSs), Industrial Internet of Things (IIoT), and Industrial Wireless Sensor Networks (IWSNs). However, his survey work focused on proposing a framework to demonstrate current challenges, define systems’ unique characteristics, analyze communication protocols, present an attack taxonomy, and evaluate real-life ICS cyber incidents.…”
