Cyber-Physical Systems Testbed Based on Cloud Computing and Software Defined Network

More standardized, networked and intelligentized nature of industry 4.0 has intensified critical infrastructures cyberthreats. According to cyber-physical systems (CPS) layered architecture and security requirements in industry 4.0, a cyber-physical systems testbed based on cloud computing and software defined network (SDN), or CPSTCS is proposed. The CPSTCS uses a network testbed based on cloud computing and SDN to recreate the cyber elements of cyber-physical systems and real-world physical devices for the physical components. The CPSTCS helps assess cyberthreats against the cyber and physical dimensions of critical infrastructures.
