Risk Assessment Model of Reliability for Information System

Abstract

We present a risk assessment model which can be used in the design phase of the information system life cycle. For each component or subsystem or and each in information system architecture, a risk factor is obtained and the severity is assessed based on hazard analysis. The risk factors in cases and the overall system risk factors are estimated using the scenarios risk factors. Finally, a Markov model is intended to set up the simulative scenarios risk factors. Within our model, we also identify critical components or subsystem and links that would require careful analysis, design, implementation, and more testing effort.
