Abstract: Cloud computing has completely transformed how businesses and individuals store, manage, and retrieve data. Nevertheless, despite its many benefits, there are inherent security challenges. This research investigates the different risks encountered by cloud computing, which consist of data breaches, insider threats, and denial of service attacks. It also covers successful prevention methods like encryption, multi-factor authentication, routine security checks, and staff education. By comprehending these dangers and putting in place strong security measures, organizations can improve the security of their cloud environments and guarantee the confidentiality, integrity, and availability of their data. Cloud computing is now being extensively researched and utilized in both academic and industrial sectors. Both cloud service providers (CSPs) and consumers benefit from cloud computing. The security issues related to cloud computing have been extensively researched in various studies.
