Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] For the convenience of understanding, the terms involved in the embodiments of the present invention are explained below:

[0025] The log audit system is a network security tool that uses big data collection, modeling, and analysis technology to detect threats and abnormal behaviors in the network in time through multi-dimensional information collection and automated correlation analysis of various network resources. Through the security linkage with firewall, intrusion prevention, terminal security and other products, it can effectively deal with threats and abnormal behaviors.

[0026] Raw events: Logs that have not yet been processed are col...

Abstract

According to the association analysis method and device of the security log, the event data and the association analysis rule base are used for generating a new event, the event data are matched with the asset library and the knowledge base for generating a three-dimensional association event, the event data can be effectively associated, and the data analysis efficiency is improved. According to the method, an on-demand distribution mechanism is carried out on the data analyzed by the association rule, that is, when the association analysis rule needs the data, the data type is input, and other data is not input, so that the problem that the resource utilization rate is too high when the association rule is subjected to real-time analysis is avoided; therefore, the pressure when irrelevant data is filtered through correlation analysis is relieved; and the data without any task subscription are directly discarded, so that the data are prevented from flowing into the downstream to carry out unnecessary performance overhead.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method and device for correlation analysis of security logs. Background technique [0002] In order to continuously respond to new security challenges, most enterprises and organizations deploy security devices such as firewalls, UTM, IDS, IPS, vulnerability scanning systems, antivirus systems, terminal management systems, WAF, DB-AUDIT, etc. in an attempt to build a security line of defense. However, in practice, most of these security defense lines can only resist security threats from a certain unilateral side, forming various "security defense islands" and cannot produce synergistic effects; more seriously, these complex IT assets and security defense facilities During the operation, a large number of security logs and events will be continuously generated, further forming a large number of "information islands", thus increasing the difficulty of finding...
