Abstract |
The increasing significance of Cyber-Physical Systems (CPS) within the framework of Industry 4.0 have not only present numerous new opportunities but have also become an integral component of the contemporary world in recent years. Hence, the process of implementing security requirements engineering for CPS is more complex as compared to the traditional software applications. Consequently, the formulation of security requirements, which delineate a system’s functionality to uphold security protocols, must be customized to meet the specific needs of these advancing technologies. Such systems are intended to directly interact with human beings, which makes security implementation an important factor for safety of human lives. This paper presents detailed overview of security requirements engineering issues present in CPS within context of industry 4.0. To handle the security issues, a metamodel for eliciting security requirements is presented. This metamodel concludes seven different aspects in which every one of them is illustrated separately. Since it is important to use the metamodel correctly, a case study is presented and applied to every component to validate the proposed metamodel to elicit security requirements for cyber-physical systems. |
