Configure Snowflake Governance Features Integration

This page details how to install the Snowflake integration for users on Snowflake Enterprise. If you currently use Snowflake Standard, see the installation guide for that integration.

1. Click Native Integrations in the left panel of the app settings page.
2. Click the +Add Native Integration button and select Snowflake from the dropdown menu.
3. Complete the Host, Port, and Default Warehouse fields.
4. Opt to check the Enable Project Workspace box. This will allow for managed write access within Snowflake. Note: Project workspaces still use Snowflake views, so the default role of the account used to create the data sources in the project must be added to the Excepted Roles List. This option is unavailable when table grants is enabled.
5. Opt to check the Enable Impersonation box and customize the Impersonation Role to allow users to natively impersonate another user. You cannot edit this choice after you configure the integration.

6. Snowflake query audit is enabled by default; you can disable it by clicking the Enable Native Query Audit checkbox.

   1. Configure the audit frequency by scrolling to Integrations Settings and find the Snowflake Audit Sync Schedule section.
   2. Enter how often, in hours, you want Immuta to ingest audit events from Snowflake as an integer between 1 and 24.
   3. Continue with your integration configuration.

7. Opt to check the Automatically ingest Snowflake object tags box to allow Immuta to automatically import table and column tags from Snowflake.

Select your configuration method

You have two options for configuring your Snowflake environment:

• Automatic setup: Grant Immuta one-time use of credentials to automatically configure your Snowflake environment and the integration.
• Manual setup: Run the Immuta script in your Snowflake environment yourself to configure your Snowflake environment and the integration.

Automatic setup

From the Select Authentication Method Dropdown, select one of the following authentication methods:

• Username and Password: Complete the Username, Password, and Role fields.

• Key Pair Authentication:

  1. Complete the Username field.
  2. When using a private key, enter the private key file password in the Additional Connection String Options. Use the following format: PRIV_KEY_FILE_PWD=<your_pw>
  3. Click Key Pair (Required), and upload a Snowflake key pair file.
  4. Complete the Role field.

Manual setup

Required privileges

The specified role used to run the bootstrap needs to have the following privileges:

• CREATE DATABASE ON ACCOUNT WITH GRANT OPTION
• CREATE ROLE ON ACCOUNT WITH GRANT OPTION
• CREATE USER ON ACCOUNT WITH GRANT OPTION
• MANAGE GRANTS ON ACCOUNT WITH GRANT OPTION
• APPLY MASKING POLICY ON ACCOUNT WITH GRANT OPTION
• APPLY ROW ACCESS POLICY ON ACCOUNT WITH GRANT OPTION

It will create a user called IMMUTA_SYSTEM_ACCOUNT, and grant the following privileges to that user:

• APPLY MASKING POLICY ON ACCOUNT
• APPLY ROW ACCESS POLICY ON ACCOUNT
• Additional grants associated with the IMMUTA database
• If you have selected to automatically ingest Snowflake object tags, which enables Snowflake tag ingestion,
  • GRANT IMPORTED PRIVILEGES ON DATABASE snowflake
  • GRANT APPLY TAG ON ACCOUNT

Run the script

1. Select Manual.

2. Use the Dropdown Menu to select your Authentication Method:

   • Username and password: Enter the Username and Password and set them in the bootstrap script for the Immuta system account credentials.
   • Key pair authentication: Upload the Key Pair file and when using a private key, enter the private key file password in the Additional Connection String Options. Use the following format: PRIV_KEY_FILE_PWD=<your_pw>

   • Snowflake External OAuth:

     1. Create a security integration for your Snowflake External OAuth. Note that if you have an existing security integration, then the Immuta system role must be added to the existing EXTERNAL_OAUTH_ALLOWED_ROLES_LIST. The Immuta system role will be the Immuta database provided above with _SYSTEM. If you used the default database name it will be IMMUTA_SYSTEM.
     2. Fill out the Token Endpoint. This is where the generated token is sent.
     3. Fill out the Client ID. This is the subject of the generated token.

     4. Select the method Immuta will use to obtain an access token:

        CertificateClient secret

        Certificate

        1. Keep the Use Certificate checkbox enabled.
        2. Opt to fill out the Resource field with a URI of the resource where the requested token will be used.
        3. Enter the x509 Certificate Thumbprint. This identifies the corresponding key to the token and is often abbreviated as x5t or is called sub (Subject).
        4. Upload the PEM Certificate, which is the client certificate that is used to sign the authorization request.

        Client secret

        1. Uncheck the Use Certificate checkbox.
        2. Enter the Scope (string). The scope limits the operations and roles allowed in Snowflake by the access token. See the Microsoft OAuth 2.0 client credentials flow documentation for details about scopes.
        3. Enter the Client Secret (string). Immuta uses this secret to authenticate with the authorization server when it requests a token.

3. Download, fill out the appropriate fields, and run the bootstrap script linked in the Setup section.

   Warning: different accounts

   The account used to enable the integration must be different from the account used to create data sources in Immuta. Otherwise, workspace views won't be generated properly.

Select available warehouses (optional)

If you enabled a Snowflake workspace, select Warehouses from the dropdown menu that will be available to project owners when creating native Snowflake workspaces. Select from a list of all the warehouses available to the privileged account entered above. Note that any warehouse accessible by the PUBLIC role does not need to be explicitly added.

Select excepted roles and users

Enter the Excepted Roles/User List. Each role or username (both case-sensitive) in this list should be separated by a comma.

Test the connection and save the configuration

1. Click Test Snowflake Connection.
2. Once the credentials are successfully tested, click Save and Confirm your changes.
