12.1 Introduction

12.1.1 Cyber-Physical Systems CPSs

Cyber-physical systems (CPSs) can be defined as the systems that consist of engineered and physical entities to perform computational and physical processes. The main idea of this new generation of systems is to enable the interaction between the physical word and the digital word through new computer-based modeling. In other words, CPSs, or what we often refer to as embedded systems, perform interaction between networked computational resources and physical systems. The CPSs are used in many useful applications in our life such as telecommunication, transportation, instrumentation, power generation and distribution, and factory automation. The cyber-physical integrated behavior of CPSs is harnessed to every component of the system, thus component–system interaction must be as safe, private, and secure as possible.

12.1.2 Security and Privacy

Predominantly, those two terms are used as synonyms while they have related definitions but not the same definitions. Data security is about ensuring that data is being accessed by only those who have the authority to do so along with having available and accurate data when needed. Data privacy is about ensuring proper use of others' ...
