Data security audit model device and method based on knowledge graph and terminal equipment

Abstract

The embodiment of the invention relates to a data security audit model device and method based on a knowledge graph and terminal equipment. A knowledge graph is constructed by performing entity relationship extraction and knowledge reasoning processing on first audit data obtained from a database; a data acquisition module is adopted to acquire second audit data needing security audit from a knowledge graph; a data analysis and mining module analyzes the audit record data in the data acquisition module to obtain an audit data rule; the polarity of the audit data rule is processed, so that a rule value can be obtained; whether the behavior in the audit record data is a violation behavior or not is judged according to a set rule threshold value; the security audit of all kinds of complex data under the background of big data can be realized; the data security audit model device based on the knowledge graph is high in security auditing efficiency, obtains the audit record data through theknowledge graph, and improves the accuracy of an audit result obtained through the analysis of the data analysis and mining module.

Description

technical field [0001] The present invention relates to the technical field of data security, in particular to a knowledge map-based data security audit model device, method and terminal equipment. Background technique [0002] With the continuous development of network technology and scale, network security incidents occur frequently, network attack methods are becoming more and more complex, and the destructive power is becoming stronger and stronger, threatening the information and equipment system security of various organizations, institutions and individuals. Traditional network security protection measures cannot perform backtracking, analysis, reverse tracking, and evidence collection on past attack events. When it is necessary to retrospectively analyze past network events and find certain rules, so as to effectively prevent the next attack, Traditional cybersecurity measures are often not up to the task. [0003] At present, the retrospective analysis of past netw...
