Cloud Computing Environment and Security Challenges: A Review

Abstract

Abstract-Cloud computing exhibits a remarkable potential to offer cost-effective and more flexible services on-demand to the customers over the network. It dynamically increases the capabilities of the organization without training new people, investment in new infrastructure or licensing new software. Cloud computing has grown dramatically in the last few years due to the scalability of resources and appear as a fast-growing segment of the IT industry. The dynamic and scalable nature of cloud computing creates security challenges in their management by examining policy failure or malicious activity. In this paper, we examine the detailed design of cloud computing architecture in which deployment models, service models, cloud components, and cloud security are explored. Furthermore, this study identifies the security challenges in cloud computing during the transfer of data into the cloud and provides a viable solution to address the potential threats. The task of Trusted Third Party (TTP) is introducing that ensure the sufficient security characteristics in the cloud computing. The security solution using the cryptography is specifically as the Public Key Infrastructure (PKI) that operates with Single-Sign-On (SSO) and Lightweight Directory Access Protocol (LDAP) which ensure the integrity, confidentiality, availability, and authenticity involved in communications and data.

Secure Cloud Infrastructure: A Survey on Issues, Current Solutions, and Open Challenges

“…A study by [19] highlighted the security issues for data transfer in a cloud. This survey provided sensible solutions for tackling possible threats.…”

“…As noticed, most of these surveys were conducted at only one level of cloud infrastructure. For instance, the surveys in [19,20,23,28], focused on only the data level, while the survey in [24] focused on only the application level. Moreover, a survey [26] was conducted on the network level and another paper [30] on the host level.…”

“…√ [19] The study focused on identified cloud computing security issues during data migration to the cloud and presented solutions for resolving potential threats.…”

From cloud computing security towards homomorphic encryption: A comprehensive review
