Concept and use Case Driven Approach for Mapping IT Security Requirements on System Assets and Processes in Industrie 4.0

In this paper, a process model is developed, which consults RAMI 4.0 and well-established core elements of safety and IT security considering the standards IEC 61508 and IEC 62443. A use case driven approach is developed with the goal to demonstrate the functionalities and validation of the process model. In different iterations, the dynamic change of the system by mapping IT security requirements on system assets and processes will be presented. The purpose of the developed process model is to assign security measures to vulnerabilities and threats of a system for Industrie 4.0.
