    Аналіз забезпечення захисту інформації в мережах 5G з технологією MASSIVE MIMO
    (ХНУРЕ, 2023) Поповська, Є. О.; Марчук, В. С.
    Advanced MIMO technology - massive MIMO is implemented in modern 5G wireless telecommunication systems. Base stations use antenna arrays with hundreds or even thousands of elements. Multi-beam antenna arrays make it possible to increase the bandwidth and spectral efficiency of the communication system. Each of the rays of the directional diagram serves its own group of users. This technology is usually implemented in the range of millimeter radio waves. The use of this range makes it possible to design antenna arrays of rather small sizes with a large number of antenna elements. 5G networks have many advantages over the previous generation of 4G. But at the same time, such networks have a number of security problems. The paper analyzes the main security problems of 5G networks with massive MIMO technology and ways to reduce them.

    Application of phased antenna array with digital beamforming to establish the internal radio network of the distributed satellite
    (ХНУРЕ, 2023) Ilchenko, M.; Narytnyk, T.; Prisyazhny, V.; Kapshtyk, S.; Denisenko, M.; Narushkevich, A.
    The possibility of application of the Phased Antenna Array with Digital Beamforming (PAA-DB) to establish the Internal Radio Network (IRN) of the Distributed Satellite (DS) is shown, which allows increasing the efficiency of the IRN by using the spatial separation of information flows between Core and Edge Satellites. The issues considered are related to choosing the Reference Coordinate System in which it is proposed to measure the relative motion of the satellite of the DS. An Orbital Coordinate System of the Core Satellite is proposed as the Reference Coordinate System. It is shown how the information about the coordinates of the Edge Satellites in the Orbital Coordinate System of the Core Satellite enables to obtain information about the coordinates of the Edge Satellites in the Orbital Coordinate System by the method of recalculation.

    Розробка пропозицій щодо кількісного оцінювання рівня реалізації вимог стандарту ISO/IEC 27001:2022
    (ХНУРЕ, 2023) Добринін, І. С.; Пашкова, А. В.
    In the modern world, information security is a key aspect for companies, confirmed by the implementation of information security management systems. The audit of these systems is an integral stage. ISO/IEC 27001 and other standards provide certain frameworks for this procedure. However, most standards are declarative or imperative in nature and do not contain specific proposals for assessing the audit results. This work proposes an approach to the quantitative assessment of the implementation of the ISO/IEC 27001:2022 standard by decomposition the audit into specific criteria. For a clear display of the adoption rate of a certain criterion, a fan chart was used, where the levels of implementation of each subprocesses was indicated.

    Методика віддаленого визначення версії MySQL сервера за допомогою пакета Kali Linux
    (ХНУРЕ, 2023) Гонтарь, І. А.; Снігуров, А. В.
    A database is a storage for any information that should be stored and proceeded. A large number of services work directly with the database. It is deployed on the servers on which the database works, for example, on a Linux server. The information that is stored on the server is a potential target for attackers. In order to have access to the server, you need to pass the configuration of the server, and then get access to the database. The correct configuration of servers and services allow reducing the risks of any malicious actions, but even a small piece of information, i.e. a version of servers or services, can become a critical vulnerability, because each version of the operating system or software can contain critical vulnerabilities that can be closed only in new versions. Therefore, such information as the server or service version can be used for malicious actions.

    Методика проведення системного аудиту на Linux серверах
    (ХНУРЕ, 2023) Гонтарь, І. А.; Снігуров, А. В.
    Linux server is a powerful and versatile system that is widely used for complex enterprise-class data centers and workload environments. One of the important ways to use the server is to perform audit server functions. This approach analyzes the state of the server for its network configurations, internal settings, handling of server resources, etc. to establish the state of the system. The state of the system affects not only server performance, but also security. Since the server may host databases, services, etc., auditing is necessary to ensure smooth and secure operation. The report identifies issues based on their prioritization for rapid countermeasures against threats.
