Cyber Security Risks of Technical Components in Industry 4.0

Industry 4.0 is a new concept of automation data exchange in manufacturing. Industry 4.0 consists of various technical components such as Artificial Intelligence (AI), IoT, OPC UA, and cloud. There could be cyber risks when these technical components are used in Industrial Control System (ICS) without security consideration. Therefore cyber risk assessment, reconsideration of implementation, operation are necessary to adopt Industry 4.0. Problems of previous research for ICS risk assessments are some of them are theoretical and conceptual methods such as simulations. Moreover, they do not focus on Industry 4.0 components.The objective of this research is to prove the concrete cyber risks and introduces corresponding secure implementations for Industry 4.0 components such as Artificial Intelligence (AI), the Internet of Things (IoT), OPC Unified Architecture (OPC UA). The proposed method has benefits for clarifying impacts on the real world by cyber-attacks through penetration tests against ICS testbed with actual machines.
