The application of cloud matter — Element in information security risk assessment

This paper proposes an improved cloud-element model for information security risk assessment. Combined with the characteristics of dynamic balance of information security risk, we propose the control means and uncontrollable factors as information security risk evaluation index. The method of constructing the sample cloud has been expatiated, and the correlation between the cloud droplet and the sample cloud and the grade limit cloud has been analyzed. The weights have been calculated by using the comprehensive weight method. Finally, an example has been used to verify it.
