A Taxonomy of Security as a Service

摘要

With the evolving expansion of threat landscape (i.e., internal and external) and the growing shortage of cybersecurity resources (i.e., tools and skills), Security as a Service (SecaaS) is gaining a momentum to fill this pressing gap. In this paper, we propose a taxonomy of existing research work in SecaaS. The taxonomy explores the current state-of-the-art in SecaaS to reason about SecaaS work with respect to three main dimensions: service operation, security solution, and threat. This taxonomy enables the SecaaS consumers and researchers to better differentiate among existing approaches and assess if they meet their security needs.
