Restricted Subscription Policy

Data owners who are not governors can write restricted subscription policies and data policies, which allow them to enforce policies on multiple data sources simultaneously, eliminating the need to write redundant local policies.

Unlike global policies, the application of these policies is restricted to the data sources owned by the users or groups specified in the policy and will change as users' ownerships change.

Once support for this feature has been enabled in your Immuta tenant,

Create a restricted subscription policy

1. Click the Policies in the left sidebar and select Subscription Policies.

2. Click Add Policy, complete the Enter Name field.

3. Select the access type:

   • Read Access: Control who can view the data source.

   • Write Access: Control who can view and modify data in the data source.

4. Select the level of access restriction you would like to apply to your data sources:

   • Allow Anyone: Check the Require users to take action to subscribe checkbox to turn off automatic subscription. Enabling this feature will require users to manually subscribe to the data source if they meet the policy.

   • Allow Anyone Who Asks (and Is Approved):

     1. Click anyone or an individual selected by user from the first dropdown menu in the subscription policy builder.

        Note: If you choose an individual selected by user, when users request access to a data source they will be prompted to identify an approver with the permission specified in the policy and how they plan to use the data.

     2. Select the Owner (of the data source), User_Admin, Governance, or Audit permission from the subsequent dropdown menu.

        Note: You can add more than one approving party by selecting + Add.

   • Allow Users with Specific Groups/Attributes:

     1. Choose the condition that will drive the policy: when user is a member of a group or possesses attribute. Note: To build more complex policies than the builder allows, follow the Advanced rules DSL policy guide.

     2. Use the subsequent dropdown to choose the group or attribute for your condition. You can add more than one condition by selecting + ADD. The dropdown menu in the subscription policy builder contains conjunctions for your policy. If you select or, only one of your conditions must apply to a user for them to see the data. If you select and, all of the conditions must apply.

     3. If you would like to make your data source visible in the list of all data sources in the UI to all users, click the Allow Discovery checkbox. Otherwise, this data source will not be discoverable by users who do not meet the criteria established in the policy.

     4. Check the Require users to take action to subscribe checkbox to turn off automatic subscription. Enabling this feature will require users to manually subscribe to the data source if they meet the policy.

   • Allow Individually Selected Users

   • with column names spelled like: Select this option, and then enter a regex and choose a modifier in the subsequent fields.
