This article is about developing a security assessment system for smart homes that use Internet of Things technology. The Internet of Things (IoT) is a nascent paradigm focused on the relationship of things or devices to each other and users. Over time, most connections on the Internet of Things go from «people interact with things» to «things interact with things». This technology is expected to be an important milestone in the development of smart homes to bring convenience and efficiency to our lives and our homes. But the introduction of this IoT technology in our homes will be important for the safety of these technologies. Connecting all smart objects inside the house to the Internet and to each other leads to new security and privacy issues, such as the confidentiality, authenticity, and integrity of the data that is perceived and exchanged. These technologies are very vulnerable to various security attacks that make a smart home based on IoT unsafe to live in, so security risks need to be assessed to assess the situation of smart homes. For any technology to be successful and widely used, it must gain the trust of users, ensuring sufficient security and confidentiality. As in all sectors, maintaining security will be the most important challenge to overcome. As homes become more computerized and filled with devices, potential computer security attacks and their impact on residents need to be investigated. This paper uses a methodology that focuses mainly on information assets and examines containers (technical, physical and human) and conducts security risk assessments to highlight various security vulnerabilities in the smart home based on the Internet of Things, the consequences and proposing measures against identified problems. that meet most safety requirements. Finally, it offers recommendations for users.

Research firm Gartner defines IoT as a network of physical objects that contain the means to interact with the environment and with each other, as well as to transmit information about their status and receive commands. McKinsey offers a less abstract definition: IoTs are sensors and drives built into physical devices and Internet connections over wired or wireless networks. IoT is developed not only by device manufacturers, but also by specialized organizations, including the International Telecommunication Union (ITU), the Industrial Internet Consortium and the IETF. In the recommendations of Y.2060 of the International Telecommunication Union, called the Overview of the Internet of Things, the Internet of Things appears as «a global infrastructure that provides complex services by connecting physical and virtual things based on existing and evolving, functionally compatible information and communication technologies». A thing in this definition means an object of the physical or virtual world that can be identified and connected to communication networks. A device in the context of IoT is an element of equipment that has the required communication capabilities and can perform measurements, operate under certain conditions, enter, store and process data. As is typical of any new concept, the process of standardizing the Internet of Things has gone from understanding the network architecture, requirements and capabilities of «things» and ways to apply them to specific technologies that allow to organize the Internet of Things direct interaction of «things» with each other and with devices and people from the outside environment. The article considers the peculiarities of the main organizations involved in IoT standardization at the global level, identifies technological, economic and social benefits of ISO standards, offers a variant of building a topology for the study of IoT protocols, which corresponds to the architecture of the Internet of Things.
