Problems solved by technology

[0004] 1. The first type needs to be modified on the application program, with few applicable scenarios, low possibility of reuse, and high cost of scene switching; 2. The actual desensitization operation of the second type of technology requires the support of the database; 3. The second type of technology desensitization Sensitization operations will consume computing resources of the database, that is to say, the actual process of desensitization is completed on the database server; 4. The second type of technology cannot be applied to database systems that do not support desensitization functions

Abstract

The invention provides a dynamic database desensitization method and system based on TCP proxy, and relates to the technical field of information security. The dynamic database desensitization method based on the TCP proxy comprises the following steps: establishing the TCP proxy between a database client and a database server; intercepting the request of the database client and the response content of the database server through the TCP proxy; and filtering and matching the request of the database client and the response content of the database server according to a preset strategy matching rule. The dynamic desensitization of the sensitive data access of the database can be realized by only modifying the configuration of the access address of the database without any code modification on the database client, and meanwhile, the database is not configured and modified. In addition, the invention further provides a dynamic database desensitization system based on the TCP proxy. The system comprises a proxy deployment module, a data interception module, a filtering and matching module, a desensitization module and a data recombination module.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for dynamic desensitization of databases based on TCP proxy. Background technique [0002] In the existing database dynamic desensitization system, the first type is to explicitly judge the data returned from the request on the database client, which fields are to be desensitized, and then use the corresponding desensitization interface for processing, and then hand it over to the final User; the second category is an improvement over the first category. It is also deployed between the client and the relational database server in the form of a TCP proxy. The corresponding desensitization function is added to the statement (at the same time, the desensitization function needs to be defined on the database) to realize the desensitization function of sensitive fields. [0003] The disadvantages of existing solutions are: [0004] 1. The first type ...
