基于堆叠条形图和平行坐标的网络数据安全可视化分析方法研究

摘要

In the field of network security,data has characteristics as isomerism,magnanimity and high-dimension.Therefore the paper researches the method of security visualization analysis.To improve analytical efficiency and capacity of data understanding,the paper brings out a new method called stacked bar chart based on entropy and a method of security visualization based on parallel coor-dinates.The method combines overview with detail which can reduce cognitive difficulty.Experi-ments show the effectiveness of these methods in analyzing network security data.%针对网络安全数据海量、高维、异构的特点，对安全可视化分析方法进行了研究。为了提高用户分析的效率和理解数据的能力，提出了基于熵的堆叠条形图设计方法和基于平行坐标的安全可视化方法。该方法把总图浏览和细节分析相结合，降低了分析人员的认知困难。实验表明该方法对分析网络安全数据有效。
