MySQL CIS benchmark script

The Center for Internet Security (CIS) has published a number of benchmark guidelines for securing MySQL databases. These guidelines cover a wide range of topics, including system hardening, user management, security configuration, and more.

To help you create a MySQL CIS benchmark script, here is a general outline that you can follow:

1. Install and configure the MySQL server:

 . Install the latest version of MySQL on your server.

. Configure the MySQL server to listen on a private network interface, rather than a public interface.

. Set a strong root password for the MySQL server.

2. Configure user account management:

. Create separate MySQL accounts for each user or application that needs to access the database.

. Assign appropriate permissions to each account based on their needs.

. Use strong, unique passwords for all MySQL accounts.

. Regularly review and revoke access for any unnecessary or inactive accounts.

3. Secure the MySQL configuration:

1. Enable SSL connections to encrypt data transmitted between the MySQL server and client applications.

2. Set the validate password plugin to ensure that all passwords meet strong complexity requirements.

3. Configure the MySQL server to use the mysql native_password authentication plugin, rather than less secure options such as mysql_old_password or mysql_clear_password.

4.Harden the MySQL system:

1. Configure the MySQL server to run as a non-root user with limited privileges.

2. Enable the MySQL firewall to block unwanted connections to the database.

3. Configure log rotation to regularly archive and rotate MySQL log files and configure log retention policies to ensure that logs are retained for a sufficient amount of time.

5. Regularly review and monitor the MySQL environment:

1. Use MySQL's built-in audit logging features to track changes to the database.

2. Regularly review the MySQL error log and slow query log to identify potential security issues or performance problems.

3. Use tools such as the MySQL Enterprise Monitor to monitor the performance and security of the MySQL server.

This is just a general outline, and you may need to customize the script based on your specific needs and requirements. It's also a good idea to consult the official CIS MySQL benchmark guidelines for more detailed information and recommendations.

Hopefully this blog clears many answers.
