ABSTRACT
An increasing number of Cyber Physical Systems is used in different areas of application like smart grid, smart factory or smart home. This paper outlines a first approach for an integrated consideration of safety and security for Cyber Physical Production Systems in the so-called Industry 4.0 context which can be interpreted as Systems of Systems. The approach is based on a use case-based model for application in the context of Industry 4.0. To realize a safe and secure operation of Cyber Physical Production Systems in System of Systems a high number of elements, relations and functions have to be taken into account. A Systems Engineering-based approach will be introduced in this paper to deal with this complexity. The approach consists of a SysML-based model which is associated with a procedure that ensures the safe and secure design of Cyber Physical Systems. Specified safety use cases will be used in the following security analysis and assessment. By harmonizing security assessment and safety use cases the integrated consideration is accomplished. The results can be used for technically solution-neutral designs in early development phases.
