Research objective: development of a method assessing the security of critical information infrastructure (CII) based on semi-natural and simulation modeling tools. The proposed method allows to develop parametric accurate simulation models of the CII object to investigate the properties of security and stability, to model the impact on the objects of computer attacks (CA). Research methods: mathematical methods of systems theory and systems analysis of probability theory, methods of graph theory, methods of simulation modeling. Research result: the proposed modeling method allows to take into account the configuration and communication features of the construction and functioning of CII objects, the dynamics and parameters of the intruder's impact on the CII objects, the existing security policy, to model the stability property, to conduct research on the degree of influence of the constituent elements on the security of the CII object. The developed modeling method makes it possible to assess the security of KII objects taking into account the configuration and communication parameters of the KII object, to reduce the dependence on expert assessments, to obtain parametrically justified security assessments.
