The Internet of Things (LOT) has been the focus of research in recent years. It is inevitable that some security problems arise due to the increased need and demand for intelligent systems and that these problems frequently come up. Security and confidentiality are the most fundamental issues for IOT applications, and despite all the work done, there are still a number of major challenges and vulnerabilities. In order to facilitate the existing security vulnerabilities and challenges, the LOT has focused on the safety of the research process. In this study, current studies in the literature arc examined in LOT devices. As a result of the examination, some results were obtained, recommendations were made and compared with other methods.
