Методологічні засади побудови захищених гарантоздатних інформаційних систем дистанційного навчання закладів вищої освіти

Abstract

The principles and methods of building secure reliable information systems (SRIS) for distance learning in higher educational institutions are investigated. The analysis of the current state of scientific re-search, practical development and application of SRIS in the processes of distance learning in universi-ties, the methodological foundations of building SRIS for distance learning at a university, formulated the main tasks of SRIS to ensure full compatibility of distance learning with full-time and part-time forms of student training, the ontology of entities is proposed for the first time educational process, based on the requirements of the legislation on higher education, the central element of which is a vir-tual learning environment. Based on the application of the constructed ontology, the priority objects of protection in SRIS are determined. In terms of building a threat model for SRIS, the components of its dependability have been analyzed, a characteristic of their possible defeat in the event of the implemen-tation of various threats is given, the factors that flow into the academic virtue of the participants in the educational process have been identified, and SRIS mechanisms have been proposed to counteract such negative factors. By the method of analogy, a model of the learning procedure for a separate academic discipline was built, a methodology for the formation of the content of test control tasks of SRIS was developed, for which an assessment of the rational number of questions in a test task was obtained, an assessment of the probability of a correct answer to one test question and random coincidence of an-swers for applicants different levels of competence (high, sufficient, medium), and the border of random coincidence of test results was calculated, the excess of which may indicate a violation of the norms of academic virtue. Application of the proposed methodology in SRIS can help to increase the level of aca-demic virtue.
