Abstract

The invention relates to a risk model construction method and device, a risk detection method and device and computer equipment. The risk model construction method comprises the steps that behavior log data and risk log data are obtained, the behavior log data comprise log data generated by behaviors using a system, and the risk log data comprise log data recorded when the system generates risks; integrating and screening the behavior log data and the risk log data to obtain risk behavior data; determining risk feature dimensions according to the triggering conditions of the risks; determining a behavior deviation degree according to the behavior log data and a predetermined behavior clustering model; and constructing a risk detection model according to the risk feature dimension, the behavior deviation degree and the risk behavior data. By adopting the method, the risk confirmation difficulty and time cost can be reduced.

Description

technical field [0001] The present disclosure relates to the field of security technologies, and in particular, to a risk model construction method, a risk detection method, an apparatus, and a computer device. Background technique [0002] With the development of science and technology, people use more and more business systems in work and life. Therefore, it is extremely important to conduct risk detection on the security of business systems. [0003] At present, the risk detection method is usually to perform risk detection on the online log files of the business system through the risk prevention and control system, thereby realizing the interception and control of risky business events. [0004] However, it is difficult to find the real risk point when conducting risk detection through the risk prevention and control system at present, because each risk event is relatively independent, such as IP risk, usage time risk and so on. It is impossible to judge from a single...
