A Survey on Security as a Service

Security as a Service (SECaaS) has been demonstrated to be one of the increasingly popular ways to address security problems in Cloud Computing but still not very widely investigated. As a new concept, SECaaS could be treated as integrated security means and delivered as a service module in the Cloud. Reviewed from a number of related literature, this paper analyzes and categorizes SECaaS into three major groups including Protective, Detective, and Reactive based on security control perspectives. We discuss the three groups and their interplay in order to identify the key characteristics and problems that they aim to address therefore revealing potentials of research and industrial application in the cloud security and service-oriented computing field.
