Comparative Analysis of Cloud Security Classifications, Taxonomies, and Ontologies

Various classifications have been proposed to describe and organize the cloud security landscape. While some are inherited from general security concepts like security attributes (confidentiality, integrity, and availability), others are based on cloud specific characteristics such as cloud service models and stakeholders' roles. Despite the extensive body of research on developing classifications for cloud computing security, a study on the principles and dimensions of these classifications have largely escaped rigorous analysis. This paper presents a comprehensive survey of the existing cloud computing security classifications, taxonomies, and ontologies. We explore their strengths, limitations, and effective use in an attempt to draw the general properties for a holistic framework that can provide a comprehensive view of cloud computing security and help better understand this evolving field. Researchers may find in this paper a road map and an overview of what exists in terms of cloud security classifications, taxonomies, and ontologies.
