| Аннотація | Context. In this paper the urgent problem of development of software of decision making support systems in information security is solved. Approach is based on a choice of rational options of response to events taking into account operational state-of-health data of a subject to protection.
Objective. Goal of the research is developing a cyber-threats counterwork model using decision support system, choosing rational variants of reactions on the occurrences in cybersecurity, and taking into account current operational data.
Method. The information object cyber security operational management system and the formation of the protection methods rational sets model which is based on a morphological approach is developed. It is proposed to find an optimal variant of the information security perimeter sets using an object function that maximizes the correlation of a consolidated figure of "information security" to consolidated figure "costs".
Results. A model for the operational management of cyber secu |
