An Analysis of Cloud Computing Multitenancy Security Challenges.

Abstract

Cloud computing is becoming the trend of information technology computational model and the cloud security is becoming a major issue in adopting the cloud for large customers [28]. Such concerns are driven by the multitenancy situation where more than one tenant are utilizing the same physical computer hardware and sharing the same software and data [1]. This has associated risks where confidentiality and/or integrity can be violated [28]. Therefore in order to propose effective security solutions and strategies a good knowledge of the current cloud implementations and practices must be acquired [28]. Such knowledge is needed in order to recognize attack vectors and attack surfaces [28]. This paper explores the specific risks in cloud computing due to multitenancy and the measures that can be taken to mitigate those risks. Before that a clear understanding of multitenancy and its benefits are demonstrated.
