Cyber-physical systems (CPS) are physical and engineered systems that interact with the physical environment. These systems exist everywhere around us, and range in size, complexity and criticality, from embedded systems used in smart vehicles, to SCADA systems in smart grids to control systems in water distribution systems, to smart transportation systems, to plant control systems, engineering workstations, substation equipment, programmable logic controllers (PLCs), and other Industrial Control Systems (ICS). CPSs are elements of the Internet of Things (IoT) and, because they have resulted from the integration of information technology with operational technology, are central to the fourth industrial revolution and to the Industrial Internet of Things (IIoT).

As CPS and ICS proliferate, and increasingly interconnect and interact among them and with us, they present an increased cyber-attack surface. As they also increasingly affect our life, their cybersecurity becomes of paramount importance. Accordingly, research into the cybersecurity and privacy of CPSs is attracting increasing attention from both industry and academia.

In line with these efforts, the main theme of this Special Issue is to investigate novel methodologies, theories, technologies, techniques, processes, and solutions for CPS cybersecurity and privacy. In this Special Issue, original research articles and reviews that present innovative ideas, proof of concepts, use cases, and results from a variety of topics relevant to ICS and CPS are welcome.

Topics addressed in the submissions include, but are not limited to:

Attacks and attack detection for CPS and ICS
Authentication and access control for CPS and ICS
Blockchain for CPS and ICS cybersecurity
Data security and privacy for CPS and ICS
Digital twin security for CPS and ICS
Embedded systems security
