Abstract

With cloud computing facilitating the migration of platforms, infrastructure and software to the cloud, security services are now following suit. Security as a service (SecaaS) is inherently a business model in which organizations can purchase on-demand security solutions to protect their data, applications, and systems, while taking advantage of what cloud computing has on offer. This chapter explores the evolution from traditional on-premise and managed security solutions to the SecaaS model, and evaluates the supporting and opposing arguments for the adoption of cloud security services. Furthermore, an overview is given for cloud security services categories with additional focus areas presented, and critical gaps identified in the literature.
