Abstract: The available tools for detecting network information can hardly meet the demands of acquiring the completeness and precision of network information for the researchers.The information fusion technology was applied to collect the network information using several detecting tools.The information from different detecting tools was fused in different layers.In data layer,the fuzzy logical statistic method was adopted to identify system type and network device,and in logic layer,the most credible information was obtained with the support of system knowledge database.

Key words: information discovery, active probing, network sniffing, information fusion

摘要： 引入信息融合技术,利用多个探测工具收集网络信息,并将来自不同类型网络探测工具的信息在不同的层次上进行融合。在数据层融合中,使用模糊逻辑的统计方法识别系统类别、区分网络设备;在决策层融合中,通过系统知识库的支持,获得最可信的网络信息。
