Security Threats and Research Challenges of IoT - A Review

The Internet of Things (IoT) refers to a telecommunication network that allows various objects to connect and share information via the Internet. It allows for machine-to-machine interaction and collaboration that does not necessitate human involvement. Its use has ushered in a new era of everything smart, including smart residences, smart cities, smart buildings, smart agriculture, and more. However, the security and privacy considerations associated with IoT pose significant hurdles. This paper provides a descriptive examination of the layered architecture of the IoT, as well as ways for overcoming security vulnerabilities using already established methods. Furthermore, based on the literature analysis, a more safe layered design that can be readily modified to improve cybersecurity problems has been proposed.
