Model of formalized information security audit of an organization with a critical infrastructure facility for compliance with international security standards
(CEUR-WS, 2025) Lishchyna, Nataliia; Lishchyna, Valerii; Kozubtsov, Igor; Yashchuk, Andrii
The article emphasizes the importance of conducting information security audits for information systems of critical infrastructure organizations. Effective protection is ensured by aligning security systems with international standards. The audit monitors and assesses compliance but remains effective only when performed regularly by trained specialists. Due to the routine nature of audits and wartime constraints, such as power outages and loss of communication, AI-based methods are often impractical. Therefore, the authors propose a temporary solution using formalized security assessment criteria with clear indicators for objective verification. The study develops a methodology for conducting audits aligned with international standards, addressing the lack of practical guidance in existing ones. It also analyzes global regulatory documents to identify typical management approaches and proposes an adaptable checklist-based methodology covering 10 key information security areas, particularly useful for organizations operating under wartime conditions. © 2025 Copyright for this paper by its authors.

Methods of Presenting the Structure of the Syllabus of a Training Discipline in a Game Form
(Dnipro, 2025) Kozubtsov, Igor; Lishchyna, Valerii
One of the modern requirements of higher education is to ensure that students have the right to freely choose educational components from the list of variable academic disciplines. This is in theory. In practice, it is difficult for students to find logical, not to mention interdisciplinary, connections with the needs of other educational components offered by the department as variable components of the educational component. This is one part of the overall problem. In the future, it is difficult for a teacher in the traditional form of a silobus of an academic discipline to explain to such students the rules of learning, to convey its logical content of structure. The author's research article is aimed at solving these interrelated partial tasks of the general problem. To achieve the purpose of the study, the following tasks were solved: the current state of research and publications in this area was analyzed; theoretical and practical basis for developing a game-based outline was developed. The main part of the study considers the purpose of the syllabus (silhouette) in the traditional form of presentation, and the peculiarities of its writing. An experimental express survey of students' opinions on the sufficient level of information to explain the need to choose this discipline and to evaluate the discipline was conducted. The result confirmed the hypothesis about the need to further improve the structure and content of the curriculum syllabus. At the same time, the students noted a significant improvement in the silhouette sample presented by the lecturer in a game form to improve mental perception. The assumption was experimentally confirmed and students demonstrated an increased interest in the discipline. Thus, the proposed approach to the formation of silhouettes can be announced as a teaching method. The article describes in detail the approach to solving the scientific and applied problem of increasing students’ interest in choosing an academic discipline through understanding the structure, logic and necessity of studying academic disciplines. This is achieved by presenting students with an algorithm for reporting stages in a non-standard game form. The scientific result expands the scientific boundaries of pedagogical sciences in the field of teaching methods for higher education students through the use of simulation as a game-based pedagogical technology. Game-based pedagogical technologies have significant potential in teaching modern students. The proposed solution is fully ready for use by the teacher in practice, but leaves it up to each teacher to adapt the algorithm to a specific discipline. The theoretical results obtained in the course of the research form the basis for its further study and improvement as a teaching methodology. It is expected that the study will have academic and practical value beyond the higher education institutions surveyed.

Classification of Landsat 8 Images Using Convolutional Neural Network Based on Minimum Noise Fraction Transform
(Helsinki, 2024-04-24) Lishchyna, Valerii
The use of remote sensing methods has transformed environmental management and regional planning by allowing the identification of items or phenomena on the Earth's surface. However, noise in picture data remains a chronic difficulty in this discipline, compromising spatial resolution and object detection accuracy. The purpose of this study is to improve the classification accuracy of Landsat 8 pictures by developing a Convolutional Neural Network (CNN) based on the Minimum Noise Fraction (MNF) transform. The goal is to evaluate MNF's efficacy in compressing and organizing multispectral images, hence reducing the influence of noise on picture categorization. The MNF transform is used to Landsat 8 image data to remove noisy bands before adopting CNN as a supervised classification approach. The current study takes use of CNN's inherent benefits in dealing with high-dimensional data, learning complicated representations, and automatically extracting key features from pictures, while simultaneously evaluating MNF's efficiency in increasing image quality. The findings show that using MNF as a preprocessing step produces images with improved quality and organization. Subsequent classification using CNN obtained an astounding accuracy of 97.41%, with a great representation of the study region and varied land use categories, highlighting the synergy between MNF and CNN in improving classification performance. The article suggests that combining MNF transform with CNN enhances classification accuracy of Landsat 8 pictures, with positive implications for developments in environmental monitoring, land use mapping, and remote sensing technologies.

(Malaysia: Publisher Seventh Sense Research Group®, 2021-06-08) Barabash, Oleg; Laptiev, Oleksandr; Sobchuk, Valentyn; Salanda, Ivanna; Melnychuk, Yulia; Lishchyna, Valerii
Given recent events, training during quarantine can only take place remotely. To ensure quality training, communication must be seamless. To do this, the network must function smoothly. The solution to this problem is functionally stable networks that allow uninterrupted transmission of information due to redundancy. An important issue is the definition of redundancy. To solve this problem, the article considers the method of synthesis of the structure of the distance learning system. The method of synthesis of network structure used for providing distance learning by the criterion of maximum functional stability on the basis of the introduction of correcting communication lines is offered. With this method, you can develop tools for self-recovery of distributed software, taking into account the characteristics of disparate computer resources through the use of redundancy. This will allow you to develop functionally stable software systems, significantly reduce the recovery time of such systems after or in the event of possible failures. To increase the efficiency of the developed method, the mathematical model of the hyper network based on two hypergraphs was improved, which allows taking into account different requirements for the quality of the network.
