AI Technical Summary

Problems solved by technology

At present, there are few achievements in the direction of automatic audit grading, especially the use of machine learning to classify user behavior, and there are very few relevant materials. Therefore, how to use machine learning to classify user behavior to reduce human input is a key issue. Matters urgently needed by those skilled in the art

Embodiment Construction

[0065] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0066] A preferred embodiment is given below:

[0067] Such as figure 1 , 2 As shown, a database behavior risk grading method in this embodiment is first defined, and the data objects supported by the known database are a finite set D={DATABASE, SCHEMA, TABLE, COLUMN, USER...}, and there are Limited operation relation OP={CREATE, DROP, ALTER, UPDATE, SELECT, DELETE...}.

[0068]According to the definition, for the database, all user...

Abstract

The invention relates to the technical field of cloud services in computers, and particularly provides a database behavior risk grading method, which is characterized in that data objects supported in a database are defined as a finite set D, the finite relationship of any operation object is OP, and a behavior standard set is S = {< d, op > d belonging to D, op belonging to OP}; weight calculation is conducted on data levels in the behavior standard set, the data levels comprise behavior weights, object weights, influence data magnitude weights and one behavior weight, and after the corresponding calculation weights are obtained, the weights are corrected according to weight statistics and a repair report. Compared with the prior art, the method has the advantages that behaviors, target types and targets are classified and subjected to weight analysis, important data are preferentially analyzed according to the system, investment of workers is reduced, efficiency is improved, and auditing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of cloud services in computers, and specifically provides a database behavior risk classification method and device. Background technique [0002] Currently commonly used audit systems often have audit item matching and audit constraint settings, both of which are accurate pattern matching user behavior data to judge the threat level. In the case of low data volume and a large number of operators, it can maintain a relative balance and meet the audit needs of users. [0003] With the development of the Internet, the data generated by various services has exploded, and the data generated by users of its services has grown geometrically. It is difficult to maintain a balance based on the original manpower, and a large number of auditors are required to analyze, classify and process the data. At present, there are few achievements in the direction of automatic audit grading, especially the use of machine lear...
