Security and Privacy Issues in Cloud and IoT Technology and Their Countermeasures

One of the most popular technologies in use today is cloud computing. It offers several data storage and access services and uses the internet rather than your computer's hard drive for programs that execute. People can use SaaS, PaaS, IaaS, and other benefits of cloud computing even though many cloud computing providers, like Google, Microsoft, IBM, and Amazon, are moving toward adopting cloud technology, which is causing a noticeable increase in the utilization of various cloud services. There are still numerous difficulties that users must overcome. IoT services with guaranteed security and sequestration are necessary for the real-time relinquishment and perpetration of similar systems for various operations, including smart metropolises, smart grids, smart homes, and smart surroundings. IoT devices produce, process, and communicate vast quantities of data sensitive to privacy and safety. In this way, security has become a major concern that expects many enterprises to use its services. This chapter examines major obstacles and the steps that must be taken to overcome them.
