This article describes an approach to using fuzzy logic methods and forming membership functions for criteria of connectivity between the significance of commands and the possibility of unauthorized access to its implementation. Relevant parameters for implementing unauthorized access through a vm or physical network to the hypervisor can be identified based on a specific set of commands, functions, instructions, procedures, utilities, or their parameters, as well as other information about software or hardware, knowledge of which allows the violator to implement each of the current threats of unauthorized access to the hypervisor. Therefore, to assess the relationship between the significance of commands for implementing unauthorized access through a vm to the hypervisor due to the presence of only qualitative evaluation parameters and the absence of their quantitative evaluations, this article offers an evaluation based on fuzzy logic methods implemented as membership functions in MATLAB.
