Immuta is compatible with Snowflake Secure Data Sharing. Using both Immuta and Snowflake, organizations can share the policy-protected data of their Snowflake database with other Snowflake accounts with Immuta policies enforced in real time.

Prerequisites:

• Snowflake integration enabled

• Snowflake tables registered in Immuta as data sources

Create Immuta Policies to Protect the Data

Required Permission: Immuta: GOVERNANCE

Build Immuta data policies to fit your organization's compliance requirements.

It's important to understand that subscription policies are not relevant to Snowflake data shares, because the act of sharing the data is the subscription policy. Data policies can be enforced on the consuming account from the producer account on a share following these instructions.

Register the Snowflake Data Consumer with Immuta

Required Permission: Immuta: USER_ADMIN

To register the Snowflake data consumer in Immuta,

1. Create a new Immuta user.

2. Update the Immuta user's Snowflake username to match the account ID for the data consumer. This value is the output on the data consumer side when SELECT CURRENT_ACCOUNT() is run in Snowflake.

3. Give the Immuta user the appropriate attributes and groups for your organization's policies.

4. Subscribe the Immuta user to the data sources.

Create the Snowflake Data Share

Required Permission: Snowflake ACCOUNTADMIN

To share the policy-protected data source,

1. Create a Snowflake Data Share of the Snowflake table that has been registered in Immuta.

2. Grant reference usage on the Immuta database to the share you created:

   Copy

   GRANT REFERENCE_USAGE ON DATABASE "<Immuta database of the provider account>" TO SHARE "<DATA_SHARE>";

   Replace the content in angle brackets above with the name of your Immuta database and Snowflake data share.

Permissions

Automatic setup permissions

When performing an automated installation, Immuta requires temporary, one-time use of credentials with the following permissions:

• 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

These permissions will be used to create and configure a new IMMUTA database within the specified Snowflake instance. The credentials are not stored or saved by Immuta, and Immuta doesn’t retain access to them after initial setup is complete.

You can create a new account for Immuta to use that has these permissions, or you can grant temporary use of a pre-existing account. By default, the pre-existing account with appropriate permissions is ACCOUNTADMIN. If you create a new account, it can be deleted after initial setup is complete.

Alternatively, you can create the IMMUTA database within the specified Snowflake instance manually using the manual setup option.

Manual setup permissions

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

Configure the integration

1. Click the App Settings icon in the navigation panel.

2. Click the Integrations tab.

3. Click the +Add Native Integration button and select Snowflake from the dropdown menu.

4. Complete the Host, Port, and Default Warehouse fields.

6. 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.

7. 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.

Select your configuration method

You have two options for configuring your Snowflake environment:

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

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:

     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:

        • 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.

          3. Enter the Client Secret (string). Immuta uses this secret to authenticate with the authorization server when it requests a token.

3. In the Setup section, click bootstrap script to download the script. Then, fill out the appropriate fields and run the bootstrap script in Snowflake.

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.

   • Table Filter: This filter determines which tables Immuta will ingest lineage for. Enter a regular expression that excludes / from the beginning and end to filter tables. Without this filter, Immuta will attempt to ingest lineage for every table on your Snowflake instance.

   • Tag Filter: This filter determines which tags to propagate using lineage. Enter a regular expression that excludes / from the beginning and end to filter tags. Without this filter, Immuta will ingest lineage for every tag on your Snowflake instance.

6. Select Manual or Automatic Setup and

Trigger Snowflake lineage sync job

Prerequisite

Trigger the lineage job

The Snowflake lineage sync endpoint triggers the native lineage ingestion job that allows Immuta to propagate Snowflake tags added through lineage to Immuta data sources.

1. Copy the example and replace the Immuta URL and API key with your own.

2. Change the payload attribute values to your own, where

   • tableFilter (string): This regular expression determines which tables Immuta will ingest lineage for. Enter a regular expression that excludes / from the beginning and end to filter tables. Without this filter, Immuta will attempt to ingest lineage for every table on your Snowflake instance.

   • batchSize (integer): This parameter configures the number of rows Immuta ingests per batch when streaming Access History data from your Snowflake instance. Minimum 1.

   • lastTimestamp (string): Setting this parameter will only return lineage events later than the value provided. Use a format like 2022-06-29T09:47:06.012-07:00.

Next steps

Once the sync job is complete, you can complete the following steps:

To migrate from the private preview version of table grants (available before September 2022) to the GA version, complete the steps below.

1. Navigate to the App Settings page.

2. Click Integration Settings in the left panel, and scroll to the Global Integrations Settings section.

3. Uncheck the Snowflake Table Grants checkbox to disable the feature.

4. Click Save. Wait for about 1 minute per 1000 users. This gives time for Immuta to drop all the previously created user roles.

5. Use the to re-enable the feature.

1. Click the App Settings icon in the sidebar and scroll to the Global Integration Settings section.

2. Click the Enable Snowflake Low Row Access Policy Mode checkbox to enable the feature.

3. Confirm to allow Immuta to automatically disable impersonation for the Snowflake integration. If you do not confirm, you will not be able to enable Snowflake low row access policy mode.

4. Click Save.

Configure your Snowflake integration

If you already have a configured, you don't need to reconfigure your integration. Your Snowflake policies automatically refresh when you enable Snowflake low row access policy mode.

1. . Note that you will not be able to enable project workspaces or user impersonation with Snowflake low row access policy mode enabled.

2. Click Save.

1. Navigate to the App Settings page.

2. Scroll to the Global Integrations Settings section.

3. Opt to change the Role Prefix. Snowflake table grants creates a new Snowflake role for each Immuta user. To ensure these Snowflake role names do not collide with existing Snowflake roles, each Snowflake role created for Snowflake table grants requires a common prefix. When using multiple Immuta accounts within a single Snowflake account, the Snowflake table grants role prefix should be unique for each Immuta account. The prefix must adhere to and be less than 50 characters. Once the configuration is saved, the prefix cannot be modified; however, the Snowflake table grants feature can be disabled and re-enabled to change the prefix.

4. Finish configuring your integration by following one of these guidelines:

   • New Snowflake integration: Set up a new Snowflake integration by following the .

   • Existing Snowflake integration (automatic setup): You will be prompted to enter connection information for a Snowflake user. Immuta will execute the migration to Snowflake table grants using a connection established with this Snowflake user. The Snowflake user you provide here must have Snowflake privileges to run these .

   • Existing Snowflake integration (manual setup): Immuta will display a link to a migration script you must run in Snowflake and a link to a rollback script for use in the event of a failed migration. Important: Execute the migration script in Snowflake before clicking Save on the app settings page.
