On the construction of data protection algorithms in cyberphysical systems

Abstract

Technology is playing an increasingly important role in our lives, and at the same time, data protection is becoming a critical issue. The article considers a particularly important sector - ensuring data security in cyberphysical systems of adaptive type, which combine physical and informational components. This paper proposes an approach presented in the form of a sequence of actions to adjust (optimize) the protection mechanisms by analyzing the state of the complex of automated systems involved in the processing of restricted access information obtained during the operation of cyber-physical systems for compliance with the required level of information security. Each subsystem processing the target information is assigned a specific security class. Optional barriers can be installed between subsystems of the same class, which ensures blocking of uncontrolled access to restricted data; management of components of all protected data. The results of approbation, representing the evaluation of using the proposed algorithm to modernize the subsystem of CPS protection against malware introduction, indicate its high efficiency.
