MCDB: Using Multi-clouds to Ensure Security in Cloud Computing

TLDR

Security is a paramount concern in cloud computing because sensitive data stored in the cloud is vulnerable to attacks on integrity and availability from insiders, outsiders, and collateral damage, yet research on mitigating these threats remains limited. This study investigates data security and privacy in cloud computing, specifically targeting data integrity, intrusion, and service availability. The authors propose a Multi‑clouds Database Model (MCDB) that distributes data across multiple cloud providers, detailing its architecture, components, and layers, and analyze its implementation for improved integrity, intrusion prevention, and availability.

Abstract

Security is considered to be one of the most critical aspects in a cloud computing environment due to the sensitive and important information stored in the cloud for users. Users are wondering about attacks on the integrity and the availability of their data in the cloud from malicious insiders and outsiders, and from any collateral damage of cloud services. These issues are extremely significant but there is still much room for security research in cloud computing. This paper focuses more on the issues related to the data security and privacy aspects in cloud computing, such as data integrity, data intrusion, service availability. It proposes a Multi-clouds Database Model (MCDB) which is based on Multi-clouds service providers instead of using single cloud service provider such as in Amazon cloud service. In addition, it will discuss and present the architecture of the proposed MCDB model and describe its components and layers. The results and implementation for the new proposed model will be analyzed, in relation to addressing the security factors in cloud computing, such as data integrity, data intrusion, and service availability.
