The concept of a hardware-software system for protecting IIoT devices

The Internet of Things is a new trend in the development of information technologies, actively spreading as interconnected functional nodes that by default have the means to ensure interaction directly with each other, or with the external environment. The development of such networks is a phenomenon that can radically change the world economy, as well as social processes. As a result of the application of this layer of information technologies, the need for direct human control over actions and operations will be eliminated. One of the most common household examples is a “smart home” – a computer network of interconnected devices using various data transfer protocols with the ability to access this network from an external network. So, thanks to IoT, it is possible to configure devices in the house by remote access. The paper deals with the main security methods against attacks and threats of IIoT devices. The information infrastructure was analyzed, an idea of the architecture of IIoT systems was obtained, and the information transmission path was identified. An analysis of the IIoT regulatory framework governing security, architecture and data exchange in IIoT systems has been carried out, documents governing the Industrial Internet of Things have been identified. The best communication protocol has been identified. Subsequently, the threats of the protocol were selected, and possible means and methods of protection were identified. For IIoT gateways, the concept of a hardware-software complex was presented as a prototype, and a comparison was made with existing solutions
