Homeostatic approach to assessing digital manufacturing securitya

Abstract

This study suggests a new digital manufacturing security paradigm based on the bio-inspired homeostasis concept to provide structural and functional cyber resilience of digital manufacturing to external destructive actions. Digital manufacturing management state indices, in particular, cyber resilience indices, have been determined. Possible approaches to calculating indices of consistency of the information layer with the physical layer, self-adaptation capability, self-similarity of performance parameters and homeostatic capability have been formulated. The analysis of the suggested approach to ensuring cyber resilience of digital manufacturing has been carried out using the software-configurable network technology. The experimental results have demonstrated the effectiveness of the suggested approach. The developed homeostatic approach lays the groundwork for building a proactive security strategy due to development of predictive methods of processing the system status monitoring results.
