Data Management:Manage DMS classification and grading templates

Usage notes

• Different templates can be associated with different instances. However, an instance can be associated with only one classification and grading template. For more information about how to associate an instance with a classification and grading template, see the Associate a classification and grading template with an instance section of this topic.

• If the sensitive data protection feature is enabled for the instance, DMS automatically associates the instance with a built-in classification and grading template. For more information about the sensitive data protection feature, see Enable the sensitive data protection feature.

• A classification and grading template can be associated with multiple instances.

• Built-in templates can only be viewed and cannot be edited.

   • Add a data category

     1. In the Data Category section of the Template Rule Details page, click the icon and select Add Category.

     2. In the Add Category dialog box, configure the Category Name and Parent Node parameters. If you do not specify a parent node, the category will be created on the root node.

     3. Click OK.

     Note

     To add a child category for an existing category, you can also perform the following operations: In the Data Category section, find the category for which you want to add a child category, move the pointer over the icon next to the category name, and then select Add Category. Enter a category name and click the icon.

   • Create a rule

     1. In the Data Category section, click the icon.

        Note

        You can also find the category for which you want to create a rule in the Data Category section, and move the pointer over the icon next to the category name.

        If both built-in and custom identification models are added to the classification and grading template, the built-in and custom identification models do not overwrite each other. For more information about identification models, see Manage detection models.

     4. Click Submit.

   • View the details of a rule

     Find the rule that you want to view and click View in the Operation column to view the basic information and identification scope of the rule.

   • Delete a rule

     Find the rule that you want to delete and click Delete in the Operation column. In the Delete message, click OK.

     Note

     To delete multiple rules at a time, you can select the rules that you want to delete and click Batch delete.

   • Modify a rule

     Find the rule that you want to modify and click Modify in the Operation column. After you modify the parameters, click Submit.

Associate a classification and grading template with an instance

You can manually associate a classification and grading template with an instance by using one of the following methods:

Method 1: Associate a template with an instance by editing the instance

1. Log on to the DMS console V5.0.

2. In the left-side navigation pane, find the instance that you want to manage and right-click the instance.

3. Select Edit.

4. In the Edit dialog box, select a template from the Classification template drop-down list.

   Note

   To select a classification and grading template, you must enable the sensitive data protection feature for the instance. For more information about the sensitive data protection feature, see Enable the sensitive data protection feature.

5. Click Submit.

6. In the Prompt message that reminds you to confirm whether to perform a full scan on metadata, click Scan Now.

   Note

   If you click Cancel, the existing sensitive data may not match the template rules because a full scan is not performed. To resolve this issue, choose Security and Specifications > Sensitive Data > Sensitive Data Assets in the top navigation bar to manually configure the scan task. For more information, see the Configure a scan task for the instance section of this topic.

7. View the status and execution results of the scan task.
