Quantitative Evaluation Method for Network Security of ATC Information System
With the continuous advancement of the construction of"smart air traffic control",the security require-ments for the air traffic control information system have gradually increased.In order to find out the risks existing in the air traffic control information system in time,a quantitative assessment method for the network security of the air traffic control information system was proposed.Combining the characteristics of the air traffic control information sys-tem with complex structure and various services,the network security assessment index system was determined from the aspects of technology and management.Firstly,the G1 method was used to determine the weight of the evaluation indicators,and the DEMATEL method was introduced to take into account the influence of factors to achieve the effect of optimizing the weight of the indicators.Then a network security evaluation model based on the cloud model was constructed to determine the risk level.Finally,several specific air traffic control information systems were selected as examples to conduct network security assessment,which verifies the availability and effectiveness of the assessment model.
