A review of testing cloud security

The cloud computing adoption process is constantly advancing whereas the security of clouds is still one of the major concerns of clients to adopt and use the new computing paradigm. To ensure a high level of security of cloud services and applications, testing is an appropriate approach to detect possible vulnerabilities before real case scenarios occur. Thus, many academic papers have been published to identify and address challenges in cloud security. However, most of the researchers focused on TaaS rather than on testing the cloud, which led to a current gap in academics. This paper presents a systematic literature review of testing cloud security. The authors elucidate a general and consistent topic overview, beginning with defining and introducing key terms. Furthermore, gaps in recent related publications are revealed, hence prospective research implications are pointed out to foster the understanding and relations of current research fields.
