According to a September 2021 report by Positive Technologies, 91% of the world's industrial companies have information systems vulnerable to cyberattacks. The industrial sector is the second most attacked sector in the U.S., and the leading one in developed countries. Ukraine ranks sixth and seventh in the top 20 for the largest industrial attacks. Many scientific publications are devoted to industrial cybersecurity in the world, but, unfortunately, in Ukraine this area of cybersecurity is poorly studied. To develop the topic of increasing the level of cybersecurity of industrial control systems, we focused on the problems of cybersecurity of the lower level of control - the operator control station of the technological plant. Previously, we investigated the problem of cybersecurity of the industrial computer network of the lower level Modbus RTU. Continuing the topic, in this paper we investigate the cybersecurity of important software - the OPC server. This study proposes to pay attention to a vulnerability that has not yet been investigated. This vulnerability is related to the fact that having an extensive network of workstations in the enterprise, an attacker can substitute OPC server on any workstation (usually the most important one in production) with his own OPC server and do it in such a way that on the one hand to bring the technological unit of the selected site to stop or crash, but on the other hand to prevent the operator of technological unit, watching the SCADA-system on the computer screen, from noticing anything. A special diagnostic system has been developed to detect a cyber attack. Appropriate software has been developed and, with its help, all solutions have been simulated in real time using components of real industrial software and Modbus network model. The developed solutions and software can be used in industry. [ABSTRACT FROM AUTHOR]

The article considers the world trends of the maritime transport complex, analyzes the current state and directions of development of stevedoring companies in Ukraine, aimed at strengthening the competitive advantages of service providers, identifies the specifics and current issues of assessing their activities. The issue of building port-industrial clusters with modern transport logistics is relevant today, as the development of trade and financial ties in the country and abroad forces countries to actively increase capacity and be constantly open to communications and trade offers. The paper identifies the main features of port financing, explores the prospects for the development of seaports and proposes a roadmap for the effective development of port infrastructure. A stevedoring company management structure is also proposed. [ABSTRACT FROM AUTHOR]
