Security risk assessment of airborne entertainment system based on


	multidimensional cloud model and entropy theory

Abstract

Abstract:

In response to the certain uncertainty, randomness, and fuzziness of existing risk assessment methods of airborne

entertainment system, as well as the strong subjectivity of their evaluation indicators, which leads to inaccurate and

non-objective evaluation results, this paper proposes a risk assessment method of airborne entertainment system

based on multidimensional cloud model and entropy theory. Firstly, more comprehensive, fine-grained, and objective system vulnerabilities are used as evaluation indicators, and based on this indicator data, a multidimensional

cloud model graph is generated to visually display the membership degree of different risks. Then, the risk value of

the entire core component is calculated based on the probability of security events occurring and the probability of

security events losses. And compared with the risk comparison table, the risk assessment result of the entire system

is obtained. Multiple experimental results have shown that the evaluation results of the proposed method in this paper have better stability, accuracy, and objectivity.

Key words:

risk assessment, cloud model, entropy weight method, airborne entertainment system
