A effort to build communication and computer science technologies is called the Internet of Things (IoT). IoT security is growing increasingly important and will have a big influence on the IoT industry since it is being used in so many different sectors. Beginning with the idea of IoT, its highlights, and foundational structure, this paper looks at the security issue of IoT in the layers of discernment, organization, and application in the IoT framework, proposes a protected development of IoT, and offers comparing secure methodologies in light of the current issues in the IoT system. At long last, a hypothetical structure for building a dependable IoT security framework will be advertised. Because of improvements in software engineering, correspondence innovation, and perceptual acknowledgment innovation, the organization of things has made some amazing progress as of late. The Internet of Things has an expansive assortment of utilizations, going from the earliest remote sensor networks utilized for military reconnaissance to present day insightful transportation, brilliant framework, shrewd medical services, savvy horticulture, brilliant coordinated operations, and that's only the tip of the iceberg
