Research On Association Analysis Of Cyberspace Resources Based On Knowledge Graph

As another important space for human life,cyberspace contains rich content and resources and has become an important research field.Today,with the continuous deepening of information technology and the continuous development of the social economy,cyber security is facing a serious threat.How to prevent the occurrence of threats to cybersecurity events is related to economic development,social stability and national security.It is of great significance to study the relationship and organization of resources in cyberspace.The hierarchical relationship between domain names can reflect the inter-institutional relationships in the real world.Web components are often detected by security experts for vulnerabilities and threats.The security of a Web site requires analysis of the relationships between Web components.Knowledge graph,as the "brain" of computers in the era of big data,can organize rich data into a huge knowledge network,imitating the human brain for thinking and analysis.This thesis proposes a method based on knowledge graph for cyberspace resource association analysis,constructs a knowledge graph of cyberspace resources and studies its efficient storage query mode,and uses Neo4 j graph database to store and query it.In order to verify the effectiveness of the proposed method,the domain data structure is abstracted from the cyberspace resource data from the top to bottom,and the rules are applied to map the domain data structure to the domain ontology,and based on the research of the knowledge description method and the open source D2 RQ platform.The structured cyberspace resource data is described as S-P-O knowledge to construct a cyberspace resource knowledge graph.In order to efficiently store and query the cyberspace resource knowledge graph,the Neo4 j graph database storage query method and the domain ontology to attribute map mapping method are studied,and the data of the cyberspace resource knowledge graph RDF type is automatically dumped into the Neo4 j attribute map.In order to analyze the cyberspace resources,the ontology-based cyberspace resource association analysis method is studied,and the cyberspace resource association model and Neo4j-based association query model are constructed.
