摘要
安全事件的可视化是大规模网络安全宏观预警的重要组成部分。根据大规模网络拓扑的结构特点,结合空间信息可视化领域中H3算法,提出了对大规模网络安全事件的宏观分布特征和局部细节进行空间可视化的处理办法。最后有效应用于教育网网络安全数据的宏观显示,实验证明为网络管理员提供了直观的显示效果并为其了解网络安全事件整体态势和从全局角度制定行之有效的控制策略提供了有力依据。
Visualization of security events is an important component of large-scale network security warning.The research includes combining structural characteristic of large-scale network topology with the H3 algorithm in the field of information visualization,providing methods for visualizing the overall distribution and local details of large-scale network security events,and applying it effectively to the visualization of network security data on CERNET.Experiment results show that the methods present a sound visual effect to the network administrator to help him/her grasp the global security situation,and then work out an effective control plan in an overall perspective.
