Network security situation prediction method and device based on knowledge graph

Abstract

The invention discloses a network security situation prediction method based on a knowledge graph. The method comprises the following steps: extracting security knowledge from network security data toconstruct a basic knowledge base; performing knowledge fusion on the safety knowledge; performing knowledge processing on the safety knowledge to obtain an extended knowledge base; constructing a Markov random field according to the extended knowledge base, and predicting a network security risk situation; wherein the network security situation prediction device comprises a knowledge extractor, aknowledge fusion device, a knowledge processor and a security predictor. According to the method, a systematic and structured network security knowledge base is provided in combination with a knowledge graph, and meanwhile, a Markov random field is combined, so that the network security risk prediction accuracy and efficiency are higher, and further guarantee is provided for network security.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a network security situation prediction method and device based on a knowledge map. Background technique [0002] With the popularization of the Internet and the rapid development of Internet technology, the scale of network users has expanded accordingly. When people enjoy the convenience brought by the network, the number of network attacks is also increasing year by year. The traditional protection methods represented by intrusion detection technology and firewall have become more and more difficult to meet the security protection requirements of large-scale networks. Risk prediction of network security situation is the key to maintaining network security. [0003] Knowledge map is a series of different graphs showing knowledge development process and structural relationship, using visualization technology to describe knowledge resources and their carriers, mining, a...
