Prerequisites

Register

This section will enable you to register the Azure Cosmos DB for SQL API instance and set up an appropriate authentication mechanism to ensure successful scanning of the data source.

Steps to register

It is important to register the data source in Microsoft Purview prior to setting up a scan for the data source.

  1. Open the Microsoft Purview governance portal by:

  2. Navigate to the Data Map --> Collections

Authentication for a scan

In order to have access to scan the data source, an authentication method in the Azure Cosmos DB database Storage account needs to be configured.

There is only one way to set up authentication for Azure Cosmos DB Database:

Account Key - Secrets can be created inside an Azure Key Vault to store credentials in order to enable access for Microsoft Purview to scan data sources securely using the secrets. A secret can be a storage account key, SQL login password or a password.

Note

You need to deploy an Azure key vault resource in your subscription and assign Microsoft Purview account’s MSI with required access permission to secrets inside Azure key vault.

Using Account Key for scanning

You need to get your access key and store in the key vault:

  1. Navigate to your Azure Cosmos DB database storage account

  2. Select Settings > Keys

  7. If your key vault is not connected to Microsoft Purview yet, you will need to create a new key vault connection

  8. Finally, create a new credential using the key to set up your scan.

Creating the scan

  1. Open your Microsoft Purview account and select the Open Microsoft Purview governance portal

  2. Navigate to the Data map --> Sources to view the collection hierarchy

  3. Select the New Scan icon under the Azure Cosmos database registered earlier

  4. Provide a Name for the scan.

  5. Choose either the Azure integration runtime if your source is publicly accessible, a managed virtual network integration runtime if using a managed virtual network, or a self-hosted integration runtime if your source is in a private virtual network. For more information about which integration runtime to use, see the choose the right integration runtime configuration article.

  6. Choose the appropriate collection for the scan and select + New under Credential
