Security models of the Internet of Things.

Abstract

The IoT is a cyber-convergent system that includes things, means of communication, target applications, and data analysis tools that support the unique identification of each object. IoT technologies play a vital role in the creation of cyber-convergent systems due to their wide usage in various spheres of life such as industry, social sphere, health care, and creating a comfortable environment. The IoT security model method ensures the confidentiality, integrity, and availability of data that is transferred between devices and also guarantees the privacy and security of end users. The creation and use of IoT systems directly affect the security and privacy of the involved and connected components. The presented study introduces an analysis of IoT architecture models with end-to-end security support. The conducted literature review reveals the challenges of various aspects of security faced by the IoT environment. Some models implementing different security strategies at different layers of the IoT are described. These include the perception layer which provides the authentication process for identifying IoT entities, the network layer which focuses on the security processes of cloud platforms, and the application layer which provides authentication and authorization for end users. The results of the analysis show that building secure IoT systems is based on three main strategies: proper configuring and ensuring the protection of all IoT devices; using secure wireless networks to connect IoT devices to corporate or global networks; constant situational awareness of security threats to IoT devices; and implementing appropriate security solutions to protect them from attacks. The maturity model of the IoT security system based on the ISA/IEC 62443 document package is also described.
