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.
本文提出了一种提高计算机系统防入侵安全性的方法。信息安全和网络安全问题的重要性得到了证实。考虑了入侵者(黑客)使用的攻击策略和破坏性行为。确定了16种不同的攻击和入侵策略。分析了计算机系统存在漏洞的原因。考虑两组原因:客观原因取决于计算机系统的硬件和软件组件,主观原因取决于人为因素。值得注意的是,客观上使计算机免受入侵的保护复杂化的主要原因之一是,同一台计算机被分配了两个不相关问题的解决方案:任务的直接解决,本质上是一个内部问题,以及通信任务,这可以被视为一个外部问题。提出了一种通过硬件冗余来提高计算机系统防入侵安全性的方法,即采用由两台内部和外部计算机组成的计算机单元来代替一台计算机。内部计算机用于直接解决任务。外部计算机负责执行通信任务。此外,还考虑了计算机系统的物理保护问题。

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.
通过对文献资料中“技能”概念的界定,我们认为:技能是一个人在其一生中所获得的知识和技能的结合。为了提高技能,你需要选择一些工具(培训、研讨会、网络研讨会、在线课程、复习课程、阅读特殊文献等)。年轻人的个人素质和态度对选择工具和取得成果很重要。作为本研究的一部分,设计和开发了构建用于监控员工技能的web应用程序的原则。web资源有一个方便的用户界面,可以查看员工的技能地图,对特定的员工技能发表评论,允许用户创建和注册现有的培训课程,生成确认掌握技能的证书,并查看统计数据。与其他类似的监控技能的程序不同,该系统提供了三种类型用户的交互:经理、导师和员工。管理员的选项包括:创建技术所有权模板、人员管理、技能管理、证书管理、通知管理;导师选项包括:技能管理、培训管理、通知管理;员工选项包括:技能管理、培训管理、通知管理、证书管理、查看统计数据、查看推荐。

The article investigates the system for contactless payments using NFC technology. The practice of acquiring as a method of trade that increases the attractiveness of the business for the client and simplifies the process of trade for owners and employees. The relevance of such a system in Ukraine and prospects for its development are determined. The availability of such systems on the market, combinations of systems that allow to obtain the same attractiveness for business and customers are analyzed. Although such systems attract customers to the business, the number of services that can provide relevant services to the customer or business remains small, and ready-made solutions that combine functionality for both customer and seller have not yet been found. The aim of the article is to present the stages of development of contactless payment systems that transfer data between client applications using NFC technology and a server based on microservice architecture. The article presents a system of contactless payments based on NFC technology, its structure and algorithm. It is stated that the principle of operation is to receive and transmit data from two end customers of the system to one of the payment systems in a certain order, which allows secure execution of payment transactions.

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.
