Creating Data Classifications

If data security levels cannot meet the data classification requirements in the case of a large amount of data, you can create data classifications for data of different values to better manage and measure your data. Data of different classifications are parallel, equal, and mutually exclusive. This section describes how to create data classifications.

Data security levels, data classifications, and identification rules are DataArts Studio instance-level configurations and can be exchanged between workspaces. In this way, data can be managed based on unified standards in the Data Map component.

Constraints

A maximum of 1,000 data classifications at five layers are allowed.
Only the DAYU Administrator, Tenant Administrator, or data security administrator can create, modify, or delete data security levels, classifications, and identification rules. Other common users do not have permission to perform these operations.
If a parent classification contains sub-classifications, the parent classification can be deleted only after the sub-classifications have been deleted.

Creating a Classification

On the DataArts Studio console, locate an instance and click Access. On the displayed page, locate a workspace and click DataArts Security.
