Return on Security Investment for Cloud Platforms

Abstract

Cloud migration is a complex decision because of the multiple parameters that contribute for or against it (e.g. available budget, costs, performance, etc.). One of these parameters is information security and the investment required in order to ensure it. A potential client needs to evaluate various deployment options and Cloud Service Providers (CSP). This paper proposes a set of metrics focused on the assessment of security controls of a cloud deployment, in terms of cost and mitigation. Such an approach can support the client to decide whether she selects to deploy part of her services, data or infrastructure to a CSP, or not.
