A New Idea of Data Fusion Method Based on Graphic Area for Information System Security Situation Assessment

Abstract— With the wise used of computer, information security has become more and more concerned by every researcher. In a large number of research directions, information security situation assessment is a hot topic. On current situation, researchers have made a lot of effort about in the field of model and framework. In fact, there are some proposed models or frameworks have showed a good result, and do withstand the test of long term practice. However, as we focus our attention on the study of models and frameworks, we ignore one of the most important points for information security situation assessment which is data fusion. Even we have a mature model of how to organize these data, we still need an effective data fusion method to fuse them, and evaluate the information security situation according to the fuse result. Some researchers have conducted a series of studies on this, but their studies are more concerned about data fuse architecture rather than the method itself. This paper proposes a new idea of data fusion method based on graphic area, we use graphs to represent the data to be fused, and use the area of graph to represent the fusion result. The proposed method is not only fuses data more accuracy but can display the result in a more intuitive way. With this method, the fusion result is easier to understand and has a better visualization. We use data from Tsinghua University information system to verify the proposed method. And the comparison result shows that our method can fuse data more comprehensively and shows a better visualization effects.

Index Terms— information system, security assessment, data fusion, hierarchical model.
