Saliieva O. Models and means of assessing the level of security of information security systems based on cognitive modeling

The dissertation is devoted to the development of functional cognitive models for assessing the level of security of information security systems circulating in information systems, to increase their security and the development of software for the implementation of assessment of the proposed models. A model for assessing the level of protection of a critical infrastructure object based on a cognitive approach is proposed. An improved model for assessing the level of security of a computer network based on a cognitive approach using fuzzy cognitive maps. The approach to determining the allowable costs of ensuring the security of the critical infrastructure and information security system and the allowable intensity of reducing the level of their protection based on the ranking of threats using the theory of fuzzy relationships has been further developed.
