The Internet of Things (IoT) has achieved widespread adoption among millions of individuals today, driven by the growing use of smart devices, including smartphones, smart cars, lighting, air conditioning, and high-speed networks. IoT is applied in various areas, including industries, healthcare, homes, agriculture, oil and gas, and education, to name a few. However, due to the many connections of IoT devices, there is no exact method or algorithm for overseeing communications and security concerns, such as Mirai-based botnet Attacks, AI-powered IoT Attacks (Emerging Threats), Satellite & Space IoT attacks, heterogeneity challenges, and Distributed Denial of Service (DDoS) attacks, which have led to enormous challenges in the IoT environment. The paper divides the challenges into three categories: recent IoT attacks, general security challenges, and existing attacks in IoT. Besides, this paper aims to review and investigate the security challenges in the IoT environment and propose various solutions to mitigate these challenges. Based on the analysis of recent IoT attacks, satellite and space attacks account for a 70% share, while in the broader security challenge, heterogeneity accounts for 80%. In existing IoT attacks, the DDoS attack poses a 90% risk.
