Authoring and publishing protection policies for Azure sources (preview)

Protection access control policies (protection policies) enable organizations to automatically protect sensitive data across data sources. Microsoft Purview already scans data assets and identifies sensitive data elements, and this new feature allows you to automatically restrict access to that data using sensitivity labels from Microsoft Purview Information Protection.

Protection policies ensure that Enterprise Admins must authorize data access for a sensitivity type. Once these policies are enabled, access control is automatically imposed whenever sensitive information is detected with Microsoft Purview Information Protection.

Actions supported

• Restrict access on labeled data assets so that only users and groups you select can access them.
• Action configured on Sensitivity Labels in the Microsoft Purview Information Protection solution.

Sources supported

• Azure SQL Database
• Azure Blob Storage
• Azure Data Lake Storage Gen2

Prerequisites

• Microsoft 365 E5 licenses. For information about the specific licenses required, see this information on sensitvity labels. Microsoft 365 E5 trial licenses can be attained for your tenant by navigating here from your environment.

• Existing Microsoft Purview accounts upgraded to Microsoft Purview single tenant model and new Portal experience, using the enterprise version of Microsoft Purview.

   Note

   To continue, you need to be a data source administrator in the collection where your Azure storage source is registered.

Create protection policy

Now that you've checked the prerequisites and prepared your Microsoft Purview instance and source for protection policies and waited at least 24 hours after your most recent scan, follow these steps to create your protection policies:

1. Sign in to the Microsoft Purview portal and select the Information Protection card. If the Information Protection solution card isn't displayed, select View all solutions and then select Information Protection from the Data Security section.

2. On the left navigation, select select Policies, then select Protection policies.

3. Select New protection policy.

4. Provide a name and description and select Next.

5. Select + Add sensitivity label to add sensitivity label(s) to detect for the policy, and select all the labels you want the policy to apply to.

6. Select Add then select Next.

7. Select the sources you want to apply the policy to. You can select multiple sources. Select Edit to manage the scope for each you select.

8. Depending on your source, select the + Include button at the top to add up to 10 resources your scope list. The policy will be applied to all the resources you select.

   Note

   Currently a maximum of 10 resources is supported, and they must be selected under Edit for them to be enabled.

9. Select Add and then select Done when your list of sources is complete.

10. Depending on your source, select the type of protection policy you want to create.

11. Select the users who will NOT be denied access based on the label. Everyone in your org will be denied access to labeled items except for the users and groups you add here.

    Important

    Ensure that any service principal accounts running data governance scans for the scoped sources are included in a Security Group. Add this Security Group to the allowed list of your protection policies. This will prevent future scans from being blocked by access restrictions on labeled files.

12. Select Next.

13. Choose whether turn on the policy right away or not, and select Next.

14. Select Submit.

15. Select Done.

You should now see your new policy in the list of protection policies. Select it to confirm that all the details are correct.
