Abstract:At present, the data center only focuses on the secure use of data and has enabled database related audit functions. However, there is still a lack of effective technical means to automatically monitor the risk behavior of the application layer and data users. In order to improve data security capabilities, this article proposes to build a set of data center behavior audit tools to effectively ensure the flow of data standardization and data security; Being able to analyze abnormal data access behavior and control data security risks through intelligent means, automatically identify abnormal data access, abnormal user behavior, and potential data security risks, assist in data security protection work, prevent data security incidents caused by data operations or internal leaks, improve security control capabilities during data usage, and achieve data security risks that can be detected, controlled, and warned. By constructing a data center behavior audit tool, we can analyze and profile the data usage behavior of individuals, identify user operation behavior, and audit user behavior, providing basic support for the analysis of data security threats and risks in Shanxi Company.
