Reliability assessment is a complex indicator that consists of four groups of properties, namely: durability, reliability, maintainability and complex indicators. In turn, the reliability properties are composed of indicators of each of the properties. It is on the basis of these indicators that the reliability of the information system used or designed. The stable functioning of information systems largely depends on the reliable operation of technical components of the system, both physical and software. The reasons that suggest an increased interest in the problems of determining the reliability of information systems are: increasing the complexity of the hardware of information systems and the emergence of highperformance information systems; slow growth in the level of reliability of its components; increasing the significance of the hardware work implemented; complexity of the conditions of use, etc. In practice, probabilistic, dynamic, predictive, and static models for determining the reliability of information systems are used to assess reliability. Each of these methods uses the presented reliability indicators as the basis for determining its reliability assessment. The concepts of information system and reliability are presented. Models and methods for determining the reliability of information systems are analysed. Criteria for the development of a formal model of research methods for evaluating the reliability of information systems are defined. A formal model has been developed for the study of methods for determining the reliability of information systems.","PeriodicalId":205855,"journal":{"name":"NBI Technologies","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125635799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are very efficient solutions for home, industry and infrastructure. A lot of complex processes can be implemented using this systems. The popularity of the industrial Internet of things is steadily growing along with the development of the Internet of things. Both of these approaches involve the exchange of data over the Internet, use of common hardware platforms and are managed by using specialized software, and this leads to an increase in the number of common vulnerabilities and possible attacks on industrial facilities. The Frost & Sullivan report shows that industrial and IT infrastructures are becoming more transparent. First of all, this is due to the development of the Industrial 4.0 standard and the refusal to isolate industrial facilities, which entails common vulnerabilities, the use of security services based on the SaaS model for industrial facilities, as well as the use of hardware devices that a potential attacker can access quite easily. But very actual problems of IoT and IIoT are information security. Many of this systems are critical and little error can stop the entire system. This is not hard for hackers because that complex system has sensitive components usually. For example simple router can have a lot of vulnerabilities. There an attacker takes a root easily in every system. To solve the problem successfully it is recommended to use complex security actions. These are secure configurations of network devices, using safe devices and protocols, regular audit, using backups, using actual politics of information security.","PeriodicalId":205855,"journal":{"name":"NBI Technologies","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132857349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors consider composite media such as noble metal nanoparticles randomly distributed in a transparent dielectric matrix and build dispersion curves of polaritons in such nanocomposites. The paper shows calculating optical parameters of the surface polariton for several values of the radius of metal nanoparticles and the nanocomposite filling parameter. The authors also present the calculations of the complex refractive index for polaritons in composites with nanoparticles of different metals. In addition, the authors find the dependences of the real and imaginary parts of the complex refractive index of the nanocomposite on the normalized frequency for membranes with different thicknesses and calculate real and imaginary parts of dielectric constant for waves in several metals. Besides, the article provides an overview of important stages in the study of surface electromagnetic waves. It shows that the variation of the structure materials, size and concentration of nanoparticles opens wide possibilities for controlling the optical properties of composite mediums and their practical application. The considered nanocomposites are artificially created media whose material parameters can be controlled. The first method consists in changing the relative volume of the nanoparticles filling of the dielectric matrix. The second method consists in changing the dielectric constant of the nanocomposite matrix. The authors emphasize that the dielectric constant of the nanocomposite in this case acquires resonant properties in contrast to the permeability of the nanoparticles themselves.","PeriodicalId":205855,"journal":{"name":"NBI Technologies","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121409097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
