Innovative technologies for evaluating effect of information security systems in the digital educational environment

Abstract

The article presents innovative technologies for evaluating the effectiveness of information security systems (ISS) in the digital educational environment. A model of the dynamics of ISS functioning using Petri nets is developed. Based on this model, a Markov model of ISS functioning, described by the Markov matrix, has been developed. A criterion for evaluating the effectiveness of ISS functioning is defined, for which the probability of timely implementation of ISS information resource protection is used. An analytical model for evaluating the efficiency criterion of ISS functioning is proposed. The results of numerical modeling of the criterion of timely implementation of information resource protection for ISS are presented "Spectrum-Z". The results of a computational experiment to evaluate the efficiency criterion for the functioning of this ISS are presented.
