The article considers an approach to increasing the security of computer systems from intrusion. The importance of the problem of information security and cybersecurity is substantiated. Strategies of attack and destructive actions used by intruders (hackers) are considered. 16 different attack and intrusion strategies are identified. The reasons for the vulnerability of computer systems are analyzed. Two groups of reasons are considered: objective reasons depending on the hardware and software components of the computer system and subjective reasons depending on the human factor. It is noted that one of the main reasons that objectively complicate the protection of a computer from intrusion is that the same computer is assigned the solution of two unrelated problems: the direct solution of tasks, which are essentially an internal problem, and the tasks of communication, which can be seen as an external problem. An approach is proposed to increase the security of computer systems from intrusion through hardware redundancy, in particular, instead of one computer, use a computer unit consisting of two computers – internal and external. The internal computer is used for the direct solution of tasks. The external computer is responsible for performing communication tasks. Additionally, the issues of physical protection of computer systems are considered.

Summarizing the definition of the concept of "skills" from the reviewed literary sources, we determine that: skills are a combination of knowledge and skills that a person has acquired during his life. To improve skills, you need to choose certain tools (trainings, seminars, webinars, online courses, refresher courses, reading special literature, etc.). Personal qualities and attitudes of young people are important in choosing tools and achieving results. As part of this study, the principles of building a web application for monitoring the skills of employees were designed and developed. The web resource has a convenient user interface, the ability to view an employee’s skill map, leave comments on a specific employee skill, allows users to create and sign up for existing training courses, generate certificates confirming mastery of a skill, and view statistics. Unlike other analogs of programs for monitoring skills, this system provides for the interaction of three types of users: manager, mentor, and employee. The manager’s options include: creating a technology ownership template, personnel management, skills management, certificate management, notification management; Mentor options include: skill management, training management, notification management; Employee options include the following: skill management, training management, notification management, certificate management, view statistics, view recommendations.

With the development of microprocessor components and, accordingly, a significant expansion of the use of computer technologies, remote measurement techniques are being developed. These include telemetry and remote control of technical systems or their components in industry, research, home appliances and other fields. In this paper, the author suggests how to build a local web-server based on a microcontroller with an ARM Cortex-M4 core, which can be interacted with via an http-browser with Internet access. The block diagram of the local web-server on the basis of the STM32F407 microcontroller with the ARM Cortex-M4 core is suggested. Hardware modeling of the local web-server with a two-processor architecture including the main controller and the Modbus processor with the RS-485 interface, which provides information exchange via the Modbus RTU protocol, is done. The main controller is equipped with an indicator system based on functionally programmable LED indicators, an LCD indicator of type BC1602A, a local keyboard, USB and SWD ports for debugging and programming of the microcontroller, an external Ethernet module providing a temperature sensor and the Modbus RTU relay module, which interacts with the main controller of the local web-server via the Modbus processor with the RS-485 interface using the Modbus RTU protocol. A software for interaction of the local web-server and a http-browser has been developed. The local web-server was tested with different types of http browsers, proved to be reliable and showed the response time which depends on the number of sensors and is less than 1 second in case of 9 sensors.
