AB The Industrial Internet of Things (IIoT) promises to bring benefits for all parties, from the machine manufacturers and system integrators to the end users, through data analytics and intelligent machines enabled by increased connectivity. The connectivity, however, brings along the possibility of unauthorised intrusions, causing disturbances in production or intralogistic systems, or in the worst scenario, acting as unintended or malicious triggers for safety hazards. In this work, we present an approach for safety and security co-assurance for machinery. Current safety and security standardisation for industrial control systems and for machinery is discussed, as well as safety and security co-assessment methodology. On this basis, an updated machine lifecycle model and an approach for safety and security risk co-assessment and risk reduction is described. Initial results based on the approach are discussed for a mixed-criticality controller device currently under development.
