The Study on Security in Internet of Things (IoT)

The Internet of Things, or IoT, has received a lot of attention lately since it has drastically altered human existence. In a wide range of applications, including smart buildings, smart health, smart transportation, and more, the Internet of Things facilitates the sharing of information or data. Sensitive information that may be disclosed is interchangeable among billions of interconnected objects. Thus, maintaining user privacy and bolstering IoT security present a significant issue. This paper aims to provide an in-depth analysis of IoT security. A taxonomy of security requirements depending on the objectives of the attacks is proposed after a number of IoT security threats are studied. In addition, current security solutions are categorised and characterised according to their use cases. In the end, open research directions and security issues are talked about.
