challenges, the main stages of the implementation of security solutions, which makes it possible to eliminate potential system vulnerabilities and determine possible information losses, are considered. It is noteworthy that global digitalization gives rise to the development of new technologies and approaches in the information industry. Devices, mechanisms and applications that were previously autonomous are becoming nodes of a global information network. Such a transformation of information technologies significantly expands the landscape of the implementation of cyber threats.

Запропоновано модифікований алгоритм Гоморі-Ху для оптимізації мереж, орієн- тованих на технологію SDH.

A multifunctional cyber-physical system for monitoring and testing remote computers in the WAN has been developed. This cyber-physical system has been built using microservice architecture. The system has used a website as a graphical interface, which in turn communicates with the main query separator, namely a web server. In addition, the database and the AES-256 encryption algorithm has been used to simplify data work, and to increase system security from external interventions.

The problem of the choice of non-cable technology on the basis of which a network for data transmission on the territory of the city of Lviv, including dense buildings and those for which the cable network is not relevant, is considered. Several basic technologies of wireless communication are considered and technology is proposed for solving this problem.

The efficient computational algorithm for optimal allocation of tasks between computers on the network has been developed. It has been designed by using dynamic programming method. The numerical example that demonstrates the effectiveness of the proposed algorithm has been solved.

This article analyzes the changes in traffic networks, obtained via Wireshark network protocol analyzer. Observations have been conducted by the following parameters: the total number of packets, the average number of packets, average packet size and average bit rate packages. The received data is used to test theoretical models.
