ANALYSIS OF METHODS, METHODS, MECHANISMS, TOOLS THEORIES OF DECISION-MAKING FOR MODELING INFORMATION PROTECTION SYSTEM

Abstract

The article presents a detailed analysis of methods, methods, mechanisms, tools of decision theory for modeling information security systems. The basic terminological concepts are given, and their detailed definition is given. The combination of elements of decision theory with information security systems is shown. The connecting link for this is probability theory. The issue of decision-making procedure as a process is studied. Emphasis is placed on the qualitative parameters of the decision-making procedure that may be suitable for information protection purposes. Analogies have been made that indicate the applicability of decision theory methods to create a model of information security system. Implementation mechanisms are shown in decision-making algorithms. With the help of decision-making theory tools, it has been established that the modeling process can be formalized since both mathematical icons and verbalization. In general, the step-by-step process of designing an information security system is described. It is concluded that formalization as a type of symbolic modeling simultaneously with the application of decision theory is the best option for the descriptive part of the information security system. Modeling has been found to be the best scientific tool for combining theoretical calculations and the practical application of a wide range of research issues, including information security. To support the decision-making of the decision-maker, in other words the offender, in the field of information protection, it is important that the security officer or system administrator has experience and skills in regulated actions. Such actions are both well-known developments in this field of activity and a synthesis of already known algorithms to achieve the state of information security in general. Automation in decision-making is possible through the introduction of a decision support system that is widely used in automated systems: computer systems and networks, especially where there is a need to analyze significant data flows.
