Creating an Elasticsearch Data Masking Task

Create an Elasticsearch data masking task to mask sensitive information in tables or columns in a specified Elasticsearch data source.

This section describes how to create an Elasticsearch data masking task.

Prerequisites

Constraints

Currently, only Elasticsearch is supported.

Creating and Running an Elasticsearch Data Masking Task

  1. Log in to the management console.
  2. Click in the upper left corner and select a region or project.
  3. In the navigation tree on the left, click . Choose Security & Compliance > Data Security Center .
  4. In the left navigation pane, choose Data Asset Protection > Data Masking and click the Elasticsearch tab. The Elasticsearch masking page is displayed.
  5. Click and set Elasticsearch to to enable Elasticsearch masking.
  6. Click Create Task. On the displayed Configure Data Source page, configure parameters according to Table 1.

    Table 1 Parameter description

    Parameter

    Description

    Task Name

    You can customize the name of a data masking task.

    The task name must meet the following requirements:
    • Contain 1 to 255 characters.
    • Consist of letters, digits, underscores (_), and hyphens (-).

    Select Data Source

    Select a data source. Currently, the value can only be Elasticsearch.

    Data Source

    NOTE:

    If no Elasticsearch instance is available, click Add to add Elasticsearch indexes. For details, see Authorizing Access to Big Data Assets.

    Elasticsearch: Select the Elasticsearch instance where the data to be masked is.

    Index: Select the index where the data to be masked is.

    Type: Select the type of the data to be masked.

  7. Click Next.

    1. Select the data columns you want to mask.
    2. Select a data masking algorithm. For details about data masking algorithms, see Configuring a Data Masking Rule.

  8. Click Next to switch to the Configure Data Masking Period page and configure the data masking period.

    Select and set the execution period of a masking task.

    • Manual: Manually enable a masking task and execute it based on masking rules.
    • Hourly: Execute a data masking task every several hours.

      Example: If the masking task needs to be executed every two hours, set this parameter to 02:00.

    • Daily: Execute a data masking task at a specified time every day.

      Example: If the masking task needs to be executed at 12:00 every day, set this parameter to 12:00:00.

    • Weekly: Execute a data masking task at a specified time every week.

      Example: If the masking task needs to be executed at 12:00 every Monday, set this parameter to 12:00:00 every Monday.

    • Monthly: Execute a data masking task at a specified time on a specified day every month.

      Example: If the masking task needs to be executed at 12:00 on the 12th day of each month, set this parameter to 12:00:00 12th day of every month.

      If you want to execute a data masking task on the 31st day of each month, the system automatically executes the task on the last day of every month.

  9. Click Next.

    Figure 2 Setting target data
    1. Select an Elasticsearch instance and index, and set Type.

      If the type you entered already exists, the system updates the data of the type in the target data source.

      If the type you entered does not exist, the system automatically creates a type with the same name in the target data source.

      If you want to use an existing type, do not set Type. Otherwise, services may be affected.

    2. Set the column name of the target data type.

      By default, the system generates the same name as the data source column. You can retain the default name or change it as needed.

  10. Click Finish.
  11. Click the Elasticsearch tab. Locate the row containing the target data masking task and click Execute in the Operation column.

  12. The data masking task is executed as configured.

    If is displayed in the Enable/Disable column, the task is disabled, and you are not allowed to click Execute.

Viewing the Status of an Elasticsearch Data Masking Task

  • On the Elasticsearch tab page, click of the target data masking task to view it execution status.
    The statuses are as follows:
    • Completed: The data masking task has been successfully executed.
    • Running: The data masking task is being executed.
    • Pending execution: The data masking task is not executed.
    • Stopped: The data masking task has been manually stopped.
    • Failed: The data masking task fails to be executed.

Editing and Deleting an Elasticsearch Data Masking Task

A masking task in the Waiting or Running status cannot be edited or deleted.

  • In the Elasticsearch data masking task list, locate the row containing the target data masking task and click Edit in the Operation column to modify masking task information. For details, see Creating and Running an Elasticsearch Data Masking Task.

  • In the Elasticsearch data masking task list, locate the row containing the target data masking task and click Delete in the Operation column.

    Deleted masking tasks cannot be restored. Exercise caution when performing this operation.
