Research On Dynamic Data Mask Technology

At present,the centralized storage of enterprise data has become an inevitable trend,most applications take the way of connecting the data center and the data sharing layer to carry out business,in the face of data leakage caused by internal staff,strengthen the protection ability of business data is very necessary.In this paper,from the perspective of improving the business data security,analyze the current threats to enterprise internal data,research and design a safe,dynamic data on the application of desensitization technology and operational audit system,the system has a system management,system security,dynamic data desensitization,and desensitization session audit four big modules,and the function of each module was coded.In this paper,after studying the data desensitization products,on the basis of present situation and the MySQL database communication protocol,in view of the enterprise demand for data desensitization,design the common elimination algorithm for a specific format,such as name,address and identity card number format,also designed a generic desensitization data output algorithm based on regular expressions,based on the above research contents,The database desensitization agent is established to realize the function of dynamic data desensitization in the production environment.The desensitization scheme is defined by setting the desensitization rules and the content of the solidified configuration table.Combined with the fine-grained access control mechanism and multi-dimensional factors,the sensitive data access control system is combined,so that people with different identities can properly access the sensitive data in the production environment.The advantage of this method is that on the basis of not affecting the communication between the original client and the database server,the security of the data in the business database is guaranteed,and the data information and data characteristics in the database are not destroyed.In order to ensure the safe and stable operation of the database,this paper also combined with the operation and maintenance audit technology,mainly realized the real-time video monitoring of the database operation and the post-playback audit function,and improved the fault tolerance rate of the operation and maintenance operation.Finally,an appropriate test case is designed to test and analyze the important function points of the system,which verifies the feasibility and security of the system,realizes the real-time desensitization operation of the MySQL business database,and improves the security of database operation and maintenance.
