Abstract

The invention discloses a log stream anomaly detecting method. The method comprises the steps of utilizing a detecting model to perform anomaly detection on log stream to be detected and judging whether the log stream to be detected is abnormal or not according to detection results, wherein the detecting model is obtained by training an initial model according to training log stream and an anomaly detecting algorithm; if the log stream to be detected has anomaly, judging whether the anomaly is a known threat or not; if the anomaly is not the known threat, updating the detecting model according to received anomaly rechecking information. The method can recognize the anomaly in the log stream and autonomously learn the new anomaly, not only recognizes the known threat, but also can learn unknown events and improves safety of a network environment. The invention further discloses a log stream anomaly detecting system which also has the beneficial effects.

Description

technical field [0001] The invention relates to the field of network security, in particular to a method and system for abnormal detection of log streams. Background technique [0002] Today, with the rapid development of science and technology, ensuring network security has become a prerequisite for the development of Internet technology. If there is a problem with network security, it will cause unimaginable blows to some enterprises. Therefore, network security has become the top priority of various Internet technologies. [0003] With the improvement of data processing and analysis capabilities, and the maturity of artificial intelligence technologies such as machine learning, technologies to solve network security problems emerge in an endless stream, but at the technical level, the principles of these technologies are basically the same. In the field of network security, the existing technology analyzes various log streams to perform anomaly discovery and security dete...
