A Survey of Cybersecurity and Resilience of Digital Manufacturing
share
Recent efforts towards industry 4.0 promote a digital manufacturing (DM) paradigm that can enhance quality and productivity, reduce inventory and the lead-time for delivering custom, batch-of-one products based on achieving convergence of 3D printing and hybrid machine tools, Automation and Robotic Systems, Sensors, Computing, and Communication Networks, Artificial Intelligence, and Big Data. A DM system consists of embedded electronics, sensors, actuators, control software, and inter-connectivity to enable the machines and the components within them to exchange data with other machines, components therein, the plant operators, inventory managers, and customers. This paper will outline the cybersecurity risks and threat vectors in the emerging DM context, assess the impact on manufacturing, and identify approaches to secure DM.
