Документ Banking security synergetic models(2019) Hryshchuk, Ruslan; Yevseiev, S. P.; Romashchenko, NataliiaThe revolutionary changes of the last decade in the banking sector have led to the blending of information and computer networks into a single information and cybernetic space, which has led to the creation of automated banking systems (ABS), which have expanded the range of state electronic services and commercial banks of the world and Ukraine. As a result, threats to such national information resource of the state as banking information resources (BIR). Security threats BIR acquired signs of hybridization. Signs of hybridity as a result of simultaneous exposure to information security threats, cybernetic security (CS) and information security (InfoSec) to BIR led to the emergence of a synergistic phenomenon whose negative signs require a radical overhaul of the concepts of existing security systems development. The article proposes mathematical methodology models for building the BIR security based on the synergistic approach of estimating hybrid threats. The proposed model forms a complex approach to assessing the current level of BIR security in the ABS, assessing the economic feasibility of introducing one or another mechanism of Technical means of InfoSec system in the ABS, depending on the banking information value, based on an advanced threat classifier.Документ Modeling of security systems for critical infrastructure facilities(PC Technology Center, 2022) Yevseiev, Serhii; Hryshchuk, Ruslan; Molodetska, Kateryna; Nazarkevych, Mariia; Hrytsyk, Volodymyr; Milov, Oleksandr; Korol, Olha; Milevskyi, Stanislav; Korolev, Roman; Pohasii, Serhii; Tkachov, Andrii; Melenti, Yevgen; Lavrut, Oleksandr; Havrylova, Alla; Herasуmov, Serhii; Holotaistrova, Halyna; Avramenko, Dmytro; Vozniak, Roman; Voitko, Oleksandr; Yerhidzei, Kseniia; Mykus, Serhii; Pribyliev, Yurii; Akhiiezer, Olena; Shyshkin, Mykhailo; Opirskyy, Ivan; Harasymchuk, Oleh; Mykhaylova, Olha; Nakonechnyy, Yuriy; Stakhiv, Marta; Tomashevsky, BogdanThe development of Industry 4.0 technologies is based on the rapid growth of the computing capabilities of mobile wireless technologies, which has made it possible to significantly expand the range of digital services and form a conglomeration of socio-cyber-physical systems and smart technologies. The First Section discusses the issues of building security systems based on the proposed Concept of multi-contour security systems, taking into account the hybridity and synergy of modern targeted cyber-attacks, their integration with social engineering methods. This approach not only increases the level of security, but also forms an objective approach to the use of post-quantum security mechanisms based on the proposed Lotka-Volterra models. The Second Section analyzes the features of the functioning of social Internet services and establishes their role in ensuring the information security of the state. An approach is proposed to identify signs of threats in the text content of social Internet services, which will allow to quickly respond to changing situations and effectively counteract such threats. A classifier of information security profiles of users of social Internet services has been developed to assess the level of their danger as potential participants in disinformation campaigns. A method for identifying and evaluating the information and psychological impact on user communities in services is proposed. Models of conflict interaction of user groups in social Internet services are considered on the example of civil movements. To effectively counter threats to information security of the state, it is proposed to use the concept of synergistic user interaction and self-organization processes in a virtual community. Particular attention is paid to countering the manipulation of public opinion in the decision-making process by users of social Internet services. The Third Section proposes a biometric security system that works to authenticate users based on a comparison of their fingerprints and certain templates stored in a biometric database. A method for determining the contour based on the passage of a curve and the filtering function of contour lines has been developed. The stage of skeletal identification is analyzed in detail. The Ateb-Gabor method with wave thinning has been developed. The performance of skeletal algorithms such as the Zhang-Suen thinning algorithm, the Hilditch algorithm, and the Ateb-Gabor method with wave decimation is analyzed. The presented results of experiments with biometric fingerprints based on the NIST Special Database 302 database showed the effectiveness of the proposed method. The software and firmware were developed using the Arduino Nano.Документ The synergetic approach for providing bank information security: the problem formulation(Національний авіаційний університет, 2016) Hryshchuk, Ruslan; Yevseiev, S. P.Continuously increasing number of threats to the security of bank information in automated banking systems (ABS) leads to a decrease in the quality of banking services provided by banks at the national and international level, regardless of their form of ownership. This situation is not least caused by the imperfection in used today mechanisms for providing bank information security. The technological complexity of new unknown threats identification, as well as the increasing sophistication in the methods of their implementation leads to the pressing need of radical revision of the existing approaches for providing security. Existing approaches are known mainly as oriented to the aggregation of forces and means of providing the security of bank information, which often leads to incomplete overlapping spectrum of threats and irrational use of resources allocated for the security. Thus, it becomes clear that the development of a fundamentally new approach to provide security of bank information is a prerequisite for the provision of high quality banking services, which this article is devoted. With this purpose, the article proposed the synergetic model of bank information security threats, which is first time since the system has allowed revealing the positions of the current state of the research problem. It is shown and proved that at the present stage of science and technology development, bank information security should be based on a fundamentally new approach, which is proposed to be called synergetic. Its implementation will provide a synergetic effect on the interaction of selected safety profiles and, consequently, demonstrate qualitatively new and previously unknown emergent properties of security system. As part of the proposed approach, the problem of increasing the level of bank information security is formalized in a general way and identified further ways of solving it. It is shown that the absence of such decisions in a bank information systems determines the relevance of the chosen for research theme and its scientific priority.
