How to implement data encryption and security protection in MySQL?

There are several ways to achieve data encryption and security protection in MySQL.

1. Utilize SSL/TLS encrypted connection: MySQL supports SSL/TLS protocol, enabling SSL/TLS connection can protect data during transmission. It is possible to configure SSL/TLS connection between MySQL server and client to ensure data is encrypted during transmission.
2. Encrypting files: MySQL offers transparent data encryption (TDE) functionality to protect data and log files by encrypting them. By configuring file encryption, sensitive information is encrypted during both storage and transmission.
3. MySQL offers encryption functions such as AES_ENCRYPT() and AES_DECRYPT() to encrypt and decrypt data. These functions can be used in applications to encrypt and decrypt sensitive data.
4. MySQL 8.0 introduced a data masking feature that allows sensitive data to be masked, concealing the actual information while preserving the format and structure of the data.
5. Utilize access control and permission management: With MySQL’s user permission management feature, fine-grained control over user permissions can be implemented to restrict access to sensitive data. Access control rules can be set to ensure only authorized users can access sensitive data.

By combining and configuring the methods mentioned above, data encryption and security protection can be achieved in MySQL, safeguarding sensitive data in the database from unauthorized access and theft.
