Security Viewpoint in a Reference Architecture Model for Cyber-Physical Production Systems

Based on the draft standard of Reference Architecture Model for Industry 4.0 (RAMI 4.0), we propose a set of concepts, techniques, and rule sets to establish a security viewpoint in the CPPS reference architecture model. We propose to use an architecture modeling tool to implement the concept and leverage existing work on models of layered architecture. We demonstrate the feasibility for security analysis and design on two example case studies.
