TOWARDS QUANTITATIVE MEASURES OF INFORMATION SECURITY: A CLOUD COMPUTING CASE STUDY

Cloud computing is a prospering technology that most organizations consider as a cost effective strategy to manage Information Technology (IT). It delivers computing services as a public utility rather than a personal one. However, despite the significant benefits, these technologies present many challenges including less control and a lack of security. In this paper, we illustrate the use of a cyber security metrics to define an economic security model for cloud computing system. We, also, suggest two cyber security measures in order to better understand system threats and, thus, propose appropriate counter measure to mitigate them.
