Liangliang Huang, Yongjun Shen, Guidong Zhang, Huixia Luo · 2015
Nowadays, information system security is faced with some serious problems which suffer increasing threats, the increasingly complicated environment and more and more uncertain factors. Moreover, there are some uncertainty, randomness and fuzziness in transforming between qualitative concepts and their quantitative expressions in the process of information security risk assessment. In order to improve objectivity and accuracy of information security risk assessment, information system security risk assessment based on multidimensional cloud model and the entropy theory is proposed in this paper.
