Abstract

The invention provides a data security protection method and device, electronic equipment and a storage medium. The method comprises the steps that permission information of a client side and a first SQL statement are obtained, the first SQL statement comprises a statement type and a field, and the field comprises an encrypted field; if the statement type is a query type, querying from a target database based on a first SQL statement to obtain a query result, the query result comprising encrypted data corresponding to an encrypted field; processing the query result according to the permission information to obtain a target query result; and returning the target query result to the client. The query result queried by the SQL statement is processed according to the obtained client permission information, so that data security access of different user permissions is realized, and a safer data security protection means is provided.

Description

technical field [0001] The present application relates to the field of data security, in particular, to a data security protection method, device, electronic equipment, and storage medium. Background technique [0002] With the advancement of information technology, people are paying more and more attention to information security. Once the private data stored in the database is leaked, the consequences will be disastrous. Therefore, the requirements for database security protection are getting higher and higher. [0003] The current security protection means are database firewalls. Users can access the database through the firewall to prevent unauthorized operations. However, some attackers can bypass the database firewall and directly connect to the database to obtain data, resulting in the leakage of private data. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a data security protection method, device, electron...
