Research On Profiling Technologies Of Key Targets' Internet Resource

Cyberspace has become the "second type of living space" for human production and life,which contains a large number of information assets related to the national economy and the people's livelihood.In order to find out the key targets' information assets,realize the informatization construction of the enterprise network infrastructure,and find the hidden security hazards from it,and then protect the key targets' Internet resources,this paper conducts a research on the key targets' Internet resource profiling technology.Among them,the key targets are banks,energy,transportation and other units that are related to the national economy and people's livelihood,and the key targets' Internet resource profile is to visually describe the key targets' Internet resource operation status and Internet resource association relationships.The main research contents of this paper are as follows:First of all,in order to realize the comprehensive detection and mining of key targets' Internet resources,based on the network topology resource discovery method,this paper proposes the discovery,expansion and verification method of key targets' main domain name resources and the discovery,expansion and verification of key targets' IP resources.Method,through the combination of active detection and passive collection,comprehensive detection of key targets' Internet resources,laying a data foundation for subsequent research.Secondly,in order to sort out the resources of the key targets' domain names and grasp the operating status of the key targets' domain name resources,this article has obtained the key targets' domain name resources,including the main domain name and the secondary domain name.Compared with the secondary domain name,the main domain name plays a more important role in DNS resolution and other processes,and has become an important infrastructure for the supervision of the Ministry of Industry and Information Technology.This paper analyzes the legality of the obtained unregistered main domain name resources in combination with policies,proposes a decision tree-based method for analyzing the unregistered legality of the main domain name,and further analyzes the reasons for its unfiled.Thirdly,in order to analyze the resources of key targets' IP addresses and understand the usage of various addresses of key targets,this article obtains and classifies the key targets' IP resources.First,based on DNS resolution records,the key targets' IP resources are divided into categories such as WEB servers.Then,we further studied the identification of CDN nodes in the WEB server,and proposed a CDN identification method based on an improved naive Bayes tree and a CDN vendor information acquisition method.Experiments show that the recognition method has a greater performance improvement compared with the existing methods.Finally,on the basis of resource detection and data analysis,the key targets' Internet resource profiling system was designed and realized.The system completes the intuitive description of the key targets' Internet resource operating status and Internet resource association relationships through the forms of geographic information graphs and logical topological graphs.
