Embodiment Construction

[0039] combine first figure 1 A method for constructing an important Internet infrastructure knowledge graph is described as an embodiment of the present invention. Such as Figure 1-2 As shown, the method includes the following steps:

[0040] Step S101: Based on the elemental analysis of the important Internet infrastructure, construct an ontology model of the important Internet infrastructure including the user role layer, the network service layer, the geographic link layer and the fragile information layer; the important Internet infrastructure includes the domain name An important collection of services for the exchange of information on the Internet by systems, web services, and network addresses;

[0041] Step S102: Obtain various data of the important Internet infrastructure, and perform knowledge extraction based on preset extraction rules for the structured and semi-structured data contained in the various data;

[0042] Step S103: Use the Neo4j graph database to...

Abstract

The invention provides an internet important infrastructure knowledge graph construction method and device, and the method comprises the steps of constructing an internet important infrastructure ontology model, and obtaining each piece of structured and semi-structured data of an internet infrastructure based on the internet important infrastructure ontology model; based on a preset extraction rule, extracting knowledge from the structured and semi-structured data, and constructing a knowledge graph; using a Neo4j graph database for storing the knowledge graph, providing two import modes of full-database import and incremental import, and using the corresponding import modes according to different import scenes to form the Internet important infrastructure knowledge graph. According to the scheme, multi-source heterogeneous data and knowledge are integrated into a unified model for analysis and utilization; the network security situation is inquired and displayed based on a knowledge graph display mode.

Description

technical field [0001] The present invention relates to the field of network security, in particular to a method and device for constructing a knowledge map of important Internet infrastructure. Background technique [0002] Network security situation awareness does not lack available information, but how to analyze and utilize multi-source heterogeneous data to gain a deep understanding of the security situation and provide support for decision-making is an urgent problem to be solved. Constructing a knowledge map for cyberspace security can construct a large amount of fragmented multi-source heterogeneous data into a whole, conduct in-depth correlation analysis and mining, and then grasp the network security situation, and provide a basis for auxiliary decision-making. [0003] At present, there are two main methods for building network security knowledge graphs. One is to construct knowledge graphs for local networks. For example, in 2016, S.Noel et al. developed a networ...
