摘要
首先就现有的网络空间搜索引擎存在的误判及漏判进行了讨论。在此基础上,提出了基于自行开发的通用基础服务器检测平台SRDS建立了CERNET基础服务器库,可以准确定位CERNET中的Web、DNS、mail和NTP这4种基础服务器。通过对检测过程获取的信息进行分析,给出了10种异常检测条件。最后展示的校园网实测案例表明了相关工作的有效性和实用性。
The paper first discusses the misjudgment and missed judgment of the existing cyberspace search engine.On this basis,based on a self-developed general-purpose basic server detection platform SRDS,the CERNET common server database is established,which can accurately detect the four common servers of Web,DNS,mail and NTP in CERNET.Ten kinds of abnormal detection conditions are given by analyzing the information obtained during the detection process.The last demonstrated case of the campus network shows the effectiveness and practicality of the relevant work.
