Abstract
The Internet of Things (IoT) has enabled significant advancements in a wide variety of scientific fields, and as a result, it has emerged as a highly attractive subject in both academia and business. The IoT aims to achieve universal Internet connectivity by transforming everyday objects into connected gadgets. Regardless of whether it results in beneficial economic and social outcomes, protecting the security and privacy of objects and users remains a critical issue that must be addressed. Addressing and evaluating IoT security risks is critical, as IoT application operatin techniques vary according to the variety of IoT environments. Thus, by discussing IoT security concerns alongside available and potential solutions , developers and businesses can identify relevant and timely responses to specific threats, resulting in the best possible IoT-based services. This article discusses the challenges inherent in implementing IoT security and some critical solutions for resolving these issues. Ten papers were extracted an ' analyzed to contribute to the corpus of literature by focusing on several critical challenges in the internet-of-things sector and shedding light on how these challenges affect a variety of domains, including healthcare, education, and business intelligence. The most frequently mentioned challenges were those related to privacy, as well as the application, network, perception, and edge layers. This paper addressed these issues by incorporating previousl discovered solutions. There has been discussion of the implications for bot researchers and practitioners.
