Software Requirements for an Ultra Large Scale System to Compute Multi Dimension Mean Failure Cost

In previous work, we presented a quantitative cyber security risk assessment model that quantifies the security of a system in financial terms. Our model assesses the cost of the failure of an information system security with regards to threats dimensions. In this assessment, we consider that the threats world can be divided into several threats dimensions and perspectives. In this paper, we discuss the specification and design of an automated tool that manage and maintains information that pertains to estimating the security risk supported by our risk assessment model.
