Handling Security Aspects in the Internet of Things: Latest Challenges and Measures to Mitigate Risks

IoT security is a critical concern that warrants significant attention. Ensuring the safety of IoT systems is just as crucial as their deployment and integration. In this study, a generic survey is covered, as well as an investigation and a better examination of the current state of security for the Internet of Things (IoT) that is included in this paper. It is the target of the Internet of Things to link everybody and everything, wherever they may be. When compared to the traditional Internet, IoT makes use of a multitude of wired and wireless networks in order to link a huge number of machines, devices with limited resources, and sensors. It is comprised of three imaginary layers: the realization layer, the network layer, and the application layer. This paper provides a description of the security problems that are present both inside and across these levels. Additionally, there are a number of security concepts that need implementation at each level. Previous work on ensuring security for each layer of the IoT is also investigated, along with countermeasures related to this topic. Last but not least, the paper delves into the various possible acquisition tactics.
