The Internet of Things, often referred to as the IoT, is an intelligent network of small sensors and other electronic devices working together. This network brings new challenges to the idea of security and privacy in end-to-end communications. The Internet of Things presents a number of critical challenges, one of the most important being the challenge of protecting the privacy of data and objects. This is one of the success factors of the Internet of Things as the lack of security measures will lead to lower user adoption (IoT). This article provides an introduction, analysis, and classification of the problems caused by privacy and security (IoT) issues in the Internet of Things (IoT). After what seemed like an eternity, a security model for the Internet of Things has finally been proposed. Thanks to IPv6 and 5G networking, in the not-too-distant future, perhaps around 2020, the Internet of Things will consist of millions of different devices. When that day comes, your rights will be the most important thing to remember. privacy policy and protection against infringement. The Internet of Things can be seen in many dimensions from different fields of science and industry; However, whatever the point of view, the IoT is still immature and exposed to various threats and attacks. Due to the nature of networking, the Internet of Things cannot use the prevention or recovery techniques used in traditional networks and the Internet. The only thing that will always change is their constant effort to develop new technologies that better meet the expectations of end users. The increase in the number of potential threats has also led to an increase in the number of preventive measures that must be taken into account to ensure security.
