Secure a Snowflake Native App with Snowpark Container Services

This topic describes the security considerations for a Snowflake Native App with Snowpark Container Services. In addition to the general security requirements for all apps, apps with containers have specific security implications and considerations. The security review process for apps with containers includes a thorough examination of the container images they contain.

Snowflake uses container image scanning tools to detect known vulnerabilities and security best practice violations.

Network isolation and egress control

Apps with containers use strict network isolation and egress control measures to help prevent unauthorized data exfiltration and to protect consumer data. Each app with containers runs in its own isolated network environment, with controlled access to external systems and services.

Snowflake uses network monitoring and filtering mechanisms to detect and block suspicious egress traffic patterns. App providers are required to explicitly declare all external end points in the application manifest, which undergoes a security review.

Consumer data is protected using the following:

  • Secure data access patterns.

  • Encryption in transit and at rest.

  • Fine-grained access controls.

The Snowflake Native App Framework ensures that app with containers can only access the specific data and resources to which an app has been granted access. This minimizes the risk of data exfiltration.

Additional approval requirements for apps with containers

Snowflake implements an additional approval process for an app with containers. The approval is mandatory before an app with containers can be published to the Snowflake Marketplace. Before a provider can create a public or private listing for an app with containers, they must be approved by the Snowflake Product Security team.

Providers who successfully pass this approval process are authorized to publish a public listing for an app with containers. This allows the app to be discoverable and accessible to Snowflake customers.

If a provider does not pass the approval process, they may not publish a listing for an app with containers.

Initiate the provider approval process

When a provider sets the DISTRIBUTION=EXTERNAL property for an application package of an app with containers, Snowflake returns the following error if the provider has not been approved to publish an app with containers:

Error Code: 093197 Account is not allowed to create application package versions or patches with
Snowpark Container Services for EXTERNAL distribution

If you receive this error, you must submit a security questionnaire to begin the approval process.

The security questionnaire assesses the following:

  • The provider’s security practices.

  • The provider’s compliance readiness.

Submitting the security questionnaire begins the provider approval process.

Evaluation of the security questionnaire

After a provider submits the security questionnaire, Snowflake’s Security and Compliance team evaluates each response and the documentation included by the provider. Responses are evaluated to ensure alignment with industry best practices and standards.

In some cases, providers may be asked to provide additional information or undergo a more in-depth review to clarify any potential concerns or risks.

After reviewing the questionnaire, Snowflake makes a decision to allow the provider to publish an app with containers. If a provider is not approved, they must wait until Snowflake Native App with Snowpark Container Services is generally available.

The provider receives an email from Snowflake indicating if they are approved or wait listed until general availability.

Scanning an app with containers

After a provider is approved, the app with containers undergoes the automated security scan. This scan includes a normal app security scan and a scan of the container images included in the app.

The guidelines for how long the security scan takes to complete are:

App size

Approximate time to complete scan

Five images or fewer / smaller than 40 GB

Less than 8 hours

Ten images or fewer / smaller than 70 GB

Less than 24 hours

Ten images or more / larger than 70 GB

2 business days or more
