Abstract:
Cloud Computing and Internet of Things (IoT) influence the constantly growing networking of systems. Both belong to Cyber Physical Systems (CPS) with are highly networked systems. The increasing establishment of CPS creates new challenges and further security and data protection aspects arise. Existing frameworks for security assessment are not suitable for CPS. The requirement criteria for CPS are scalability, real-time, performance, functional safety and volatility. Data security has so far been evaluated by the two-level trust model (secure and insecure). This trust model is not suitable for CPS. The reasons for this are the large amount of data and the wide variety of data types. This paper presents the required criteria for security assessment of CPS, the development of the Process-oriented Framework for Security Assessment of Cyber Physical Systems and the application of the security model. The Process-oriented Framework for Security Assessment of Cyber Physical Systems includes the steps analysis of the application, security, scalability and real-time assessment and automated mapping of security measures.
