A Comprehensive Review on Data Security and Threats for Data Management in Cloud Computing

Abstract

The cloud is a network of virtual computers that are linked together and may exhibit and offer computational capabilities continuously depending on certain Service Level Agreements (SLAs) that have been agreed between the parties to a contract between the clients and the internet provider. Cloud computing has several benefits, including endless computational resources, cheap cost, security controls, hypervisor protection, instantaneous elasticity, high throughput, and fault-tolerant solutions with increased performance. Since cloud computing is a comparatively recent computing model, there exists a lot of uncertainty about how well confidentiality of all levels, including host, network, data levels, and implementation, can be achieved. As a result, there still are important obstacles to cloud computing adoption. These constraints include security issues concerning privacy, compliance, and legal issues. When databases and software applications are moved from the cloud to large data centers, data management becomes a major challenge. Numerous security issues may develop while using cloud computing, including issues with privacy and control, virtualization and accessibility issues, confidentiality, management of credentials and identities, authentication of responding devices, and authenticity. In this paper, an effort is made to offer a comprehensive review of data security and threats in cloud computing.
