Analysis of Criteria for Ensuringinformation Security of Scientific and Educational Resources
(Rezekne Higher Educ inst-rezeknes Augstskola, 2018) Rakhmatullaev, Marat; Normatov, Sherbek; Department of Information and Library Systems
At present, information and knowledge in the field of science and education are strategic resources. From their formation, renewal, distribution depends not only the scientific and educational spheres, but also the socio-economic development of the country. Therefore, the confidentiality, integrity and accessibility of databases of a scientific and educational nature are an important subject of research. The purpose of this article is to conduct an analysis of methods, criteria for assessing units of scientific information in terms of ensuring information security. Classification of criteria for the evaluation of scientific and educational information (SEI), their systematization, analysis of problem of ensuring the security of information resources are given. Also, the information infrastructure development indicators and projects implemented in the field of information security are outlined. Evaluation of SEI units is carried out by experts who themselves have a weighting factor and are dependent on their qualifications. The results of the research are the basis for the creation of an automated system for ensuring information security in the corporate library system of academic libraries. The corporate network forms an electronic public library, distributes the SEI between resource users. The information security system will ensure the regulation of access to resources.

Expert System With Fuzzy Logic for Protecting Scientific Information Resources
(Ieee, 2020) Rakhmatullaev, Marat; Normatov, Sherbek; Department of Information and Library Systems
Analysis of the state of development of research on the protection of valuable scientific and educational databases, library resources, information centers, publishers show the importance of information security, especially in corporate information networks and systems for data exchange. Corporate library networks include dozens and even hundreds of libraries for active information exchange, and they (libraries) are equipped with information security tools to varying degrees. The purpose of the research is to create effective methods and tools to protect the databases of the scientific and educational resources from unauthorized access in libraries and library networks using fuzzy logic methods. As a model and solution method, a fuzzy model of second-type correspondences is proposed, which makes it possible to comprehensively solve the problem of identifying threats in the event of a situation, as well as provide recommendations on how to eliminate them. For the creation of a knowledge database, experts are involved who determine the functions of belonging to "Situation-Threat-Methods of eliminating threats". The research results are used in the expert system the corporate network of electronic libraries to protect scientific and educational information from unauthorized access.

Extended Model of Access Control for the Library Information Systems
(Ieee, 2017) Normatov, Sherbek; Rakhmatullaev, Marat; Department of Information and Library Systems
In this article were analyzed existing models of access control in information systems, and was explored an extended model of building access control for an automated information and library system. As the operating factor on the proposed model, operators and their functions were chosen. In addition, the generalized structure and algorithm of the proposed model is given.
