Abstract

The purpose of the article: analysis of the problem of ensuring timely authorized access to the resources of the electronic information and educational environment of universities of federal executive authorities and identification of possible directions for its solution. Research methods: system analysis of the problem of ensuring access of officials of universities of federal executive authorities to the resources of the electronic information and educational environment. The result obtained: approaches to improving the existing access control model, optimizing the role-based access scheme and determining unauthorized access attempts based on machine learning methods are proposed. Scope of the proposed approach: access control system of the electronic information and educational environment of universities of federal executive authorities. Scientific novelty: consists in a comprehensive analysis of the problem of creating and functioning of the electronic information and educational environment of universities of federal executive authorities, during which the structure of this environment is determined and its characteristic features are highlighted. Based on the analysis of information security threats in the electronic information and educational environment, the necessity of creating an access control system to its resources, which provides timely authorized access, is substantiated. The proposed approaches to improving the access control system affect not only the improvement of the existing access model by supplementing it with solutions available in the attribute-based access model, but also the optimization of the role- based access scheme using the developed genetic algorithm and the detection of unauthorized access attempts associated with overcoming access rules, based on application of machine learning methods. Experimental results are presented that confirm the effectiveness of the proposed approaches.
