The security level of a field. The stored business data is classified into different security levels based on its nature. For example, the values of some fields such as mobile numbers and ID card numbers are sensitive data. Unless otherwise specified, the values of these fields cannot appear in plaintext during regular queries on table data.
- When you query data in the SQLConsole, sensitive fields and confidential fields that you have no permission to access appear as a string of asterisks (**) by default.
- To query, export, or change sensitive fields and confidential fields, you must apply for the corresponding permissions on them separately.
- The database administrator (DBA) or Data Management Service (DMS) administrator can configure special approval processes if the data to be exported or changed involves sensitive fields and confidential fields.
Log on to the DMS console.
In the left-side navigation pane, right-click the target database and select Table Details.
On the page that appears, click the plus sign (+) to the left of the target table name to show the details of the target table. On the Column tab, click Adjust.
DMS automatically approves applications for raising the security level of a field. Applications for lowering the security level of a field must be approved based on the process specified by the DMS administrator or DBA.
