Scanning Sensitive Data in Assets

A sensitive data discovery task automatically obtains sensitive data table information in data assets.

Procedure

  1. Log in to a database encryption and access control instance as the sysadmin user.
  2. In the navigation tree on the left, choose Sensitive Data Discovery > Sensitive Data Scanning.
  3. Find the target data asset and click Task Configuration. In the Task Configuration dialog box, set a sensitive data discovery task.

    Table 1 Parameters for a sensitive data discovery task

    Parameter

    Description

    Sample Count

    Set the number of scanned samples.

    Sampling scanning refers to extracting a certain amount of data from a dataset for identification. The more samples, the more accurate the recognition. The fewer samples, the faster the scanning speed.

    Maximum Number of Threads

    Set the maximum number of threads used by a task.

    The sensitive data discovery task can use multiple threads. The more threads, the higher the scanning efficiency and the more device resources.

    Select Schemas

    Select the database schema to be encrypted.

    In the Available Schemas area on the left, select the target mode and click > to move the mode to the selected mode.

    Select Table

    After a schema is selected, all tables in the schema are automatically selected. If you select only a single schema, you can adjust the number of tables in the schema as required.

    If some tables do not need to be scanned, select the target objects in the selected tables on the right and click < to move the target objects to available tables.

    Sensitive Data Selection

    Select an industry template from the drop-down list box. After you select an industry template, the system scans the data types set in the template.

    The system has built-in common industry templates. You can also customize industry templates. For details, see Adding an Industry Template.

    If you select do not use a template, manually set the types of data to be scanned in Data Types to Discover module.

    Data Types to Discover

    Manually select the types of data to be scanned.

    This parameter is available only when Sensitive Data Selection is set to no template.

  4. Click Save.
  5. Find the target data asset and click to execute the sensitive data discovery task. After the execution starts, the system automatically scans and identifies sensitive data. The scan duration depends on the amount of data to be scanned. The larger the amount of data, the longer the scan duration. You can view the scan progress on the page. After the execution is complete, the Task Status is Scan Finished.
