Create Hadoop & Files Policy

To create a policy in Hadoop & Files, click Policy > Hadoop & Files. The Add Policy button will allow you to create a policy.

On clicking Add Policy button, the New Policy screen appears. The New Policy screen is divided into two sections. 

  1. The top section displays the fields in which the user needs to provide the policy name and its description.

  2. The bottom section in the screen displays the list of all Pre-Defined Sensitive Types, Custom Sensitive Types and the Protection/CUPS options. Using Protection/CUPS option, you can protect the sensitive information.

Enter the following details to create a policy.

  1. Policy Name: Enter the name of the policy. The name must be unique for each policy. Blank spaces and special characters are not allowed in this field except _ (underscore) and – (dash).

  2. Description: Enter a brief description for the policy. This field accepts letters, numbers, symbols as well as special characters. It can hold 256 characters.

  3. Include Privacy Dashboard View: Check this option, if you want to display the data related to policy in the Privacy View tab under the Reports module.

  4. Sensitive Type List: A list of all the Pre-Defined and Custom Sensitive Type is displayed in the bottom section of the screen along with the Protection and CUPS options.

    To include the Sensitive Type in the policy, check the checkbox available with the sensitive type name. You can also select the entire group of Sensitive Type. To do so, check the checkbox available with the Sensitive Group name.


    E.g., in the above image, to select the entire group of Credit Card, the checkbox available with the Credit Card Sensitive Group name has been checked. Also, to select only one Sensitive Type in the entire group, the checkbox available with the DOB (BEST SUITED for structural data) has been checked. A user can define its own Sensitive Type in the New Sensitive Type tab defined under the Sensitive Type Manager.

  5. The Protection Option column has the drop-down field. On clicking the drop-down next to selected sensitive type displays the list of all supported Protection Options. Select the required protection option from the drop-down.

  6. The bottom section displays the CUPS options. There are three parameters for CUPS option.

    1. Consistent (C)

    2. Keep Null

    3. Report Unique and Total Count

  7. To use the CUPS functionality, check the Consistent, Keep Null, Report Unique and Total Count checkboxes, as deemed fit, corresponding to Sensitive Types displayed under the NEW POLICY screen.

  8. Click Save button to make the changes effective, else click Cancel button.

  9. Click Save As button if you want to save the policy with same configuration but with different name.

For Hadoop & Files, the Keep Null checkbox enables the user to retain any special characters, spaces, null values (case sensitive) etc., as it is in the masked-out file. The default value for Keep Null is true. The user can set the regex pattern (\t*|\s*|(null)?) for property nulldefinition.regexpattern in the respective properties file of the IDP (LFA, HFDS, Cloud).
