Assessment and Information Security Provision of the Decision Support Process in Technogenic Object Management Systems

Abstract

The paper considers the information technology of assessment and provision of complex information security of decision-making process in human-machine management systems for technogenic objects, which complements the theory and methods of solving reliability and survivability problems of multilevel systems, based on the interaction of the set of their workability indicators, human factor and information security indicators in the decision-making process to ensure the efficiency of critical object management. To assess the impact of a set of indicators of non-factors of information security, external, production, and human factors on the decision-making process of decision-maker in the management of critical objects, a fuzzy Bayesian network was built, which allowed, based on expert knowledge, to assess the probability of the critical object's information security states. To practically substantiate the obtained results, an experiment was carried out, the results of which confirmed the practical value of the information technology, which can be used to assess and ensure comprehensive information security of the decision support process in man-machine management systems for technogenic objects.
