Comprehensive analysis of security issues in cloud-based Internet of Things: A survey

The Internet of Things (IoT )has emerged as the largest computing platform, enabling IoT devices to sense real-world conditions such as temperature, humidity, pressure, and cloud prediction. However, the security of IoT systems is crucial due to their direct impact on human life. With the expansion of processing and communication capabilities to numerous devices, IoT has become a vast network where connectivity is ubiquitous. This paper focuses on the security issues of cloud-based IoT, specifically access control, network security, data security, and privacy, which are the four main components of cloud-based IoT. By analyzing and comparing existing research papers on security in cloud IoT and IoT in general, we identify proposed solutions. Most researchers have concentrated on a single component, while only a few have addressed two components. Consequently, our research aims to bridge the gap in Cloud IoT security by focusing on more than two components. We propose the utilization of methods such as Machine Learning and blockchain to enhance security, drawing on the strengths highlighted in previous works. Our future focus will involve exploring potential attacks in cloud IoT and developing a comprehensive method that encompasses atleast three security components of cloud IoT security.
