Ensure DML/DDL Grants are Limited to Specific Databases and Users

How it is checked

Audit method: Manual review

This recommendation cannot be checked automatically. A scan lists it with these instructions when you pass --include-manual.

Run SELECT User, Host, Db FROM mysql.db WHERE Select_priv='Y' OR Insert_priv='Y' OR Update_priv='Y' OR Delete_priv='Y' OR Create_priv='Y' OR Drop_priv='Y' OR Alter_priv='Y'; and ensure every returned user is permitted these privileges on the indicated database.

How it is fixed

Fix method: Guidance or infrastructure patch

REVOKE SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER ON <db>.* FROM '<user>'@'<host>'; for each unauthorized grant.
