Ontology-Based Security Tool for Critical Cyber-Physical Systems

Abstract

Industry 4.0 considers as a new advancement concept of the industrial revolution, which introduces a full utilization of Internet technologies. This concept aims to combine diverse technological resources into the industry field, which enables the communication between two worlds: the physical and the cyber one. Cyber-physical Systems are one of the special forces that integrate and build a variety of existing technologies and components. The diversity of components and technologies creates new security threats that can exploit vulnerabilities to attack a critical system. This work introduces an ontology-based security tool-chain able to be integrated with the initial stages of the development process of critical systems. The tool detects the potential threats, and apply the suitable security requirements which can address these threats. Eventually, it uses the ontology approach to ensure that the security requirements are fulfilled.
