A Detailed Study on Security and Privacy Analysis and Mechanisms in Cloud Computing

When it comes to delivering IT services to businesses or consumers, the cloud provides a scalable, reliable, and cost-effective option. However, there is an increased risk associated with cloud computing due to the fact that critical operations frequently go to another organization, making it more difficult to preserve privacy and security of data, sustain data and availability, and prove compliance. It is a difficult issue in cloud computing to ensure the security of outsourced data. Data integrity should be verified by the client or an external auditor before being outsourced. Many methods using various techniques, including Proof of Retrievability, proved data ownership, privacy preservation, etc., have been developed for this goal. Various security strategies to address the current security vulnerabilities have been offered in the literature by researchers and impacted companies. Security and privacy concerns in cloud computing are also well reviewed in the literature. Unfortunately, the literature presented works lack the adaptability to counter diverse attacks without undermining cloud security goals. As a corollary, the literature has highlighted security and privacy vulnerabilities without giving suitable technological techniques to alleviate both security and privacy risks. However, studies that provide technological responses to security issues have not provided enough reasoning for the existence of these dangers. The purpose of this article is to discuss potential cloud security and privacy challenges that might arise and need a flexible approach to finding a workable solution. This study provides a comprehensive review of the relevant literature, discussing how safe cloud conflicts have made the suggested models from prior works obsolete while also taking into consideration the works' adaptability to handle future threats. The STRIDE methodology is then used to convey, from the user's point of view, the security concerns associated with cloud computing. It also analyzes the literature's many ineffective solutions and gives guidance on how to set up a safe, flexible cloud infrastructure.
