Key Topics in Cloud Computing Security: A Systematic Literature Review

Based on a systematic literature review (hereafter SLR), this paper identifies the key themes and topics in cloud computing security. Findings from an analysis of 275 peer-reviewed publications show that cloud security solutions and cloud security challenges are the two most dominant themes. The other themes identified include guiding frameworks and methodologies and general security requirement. Topics related to each of these themes were also identified and ranked, hence providing a comprehensive map of the research on cloud security. Implications for research and practice are discussed.
