"provider": "Azure", "serviceType": "Databricks", "serviceName": "Analytics Services", "displayName": "Ensure that Azure Databricks is deployed in a customer-managed virtual network (VNet)", "description": "Networking for Azure Databricks can be set up in a few different ways. Using a customer-managed Virtual Network (VNet) (also known as VNet Injection) ensures that compute clusters and control planes are securely isolated within the organization’s network boundary. By default, Databricks creates a managed VNet, which provides limited control over network security policies, firewall configurations, and routing.", "rationale": "Using a customer-managed VNet ensures better control over network security and aligns with zero-trust architecture principles. It allows for:\n• Restricted outbound internet access to prevent unauthorized data exfiltration.\n• Integration with on-premises networks via VPN or ExpressRoute for hybrid connectivity.\n• Fine-grained NSG policies to restrict access at the subnet level.\n• Private Link for secure API access, avoiding public internet exposure.", "impact": " * Requires additional configuration during Databricks workspace deployment. * Might increase operational overhead for network maintenance. * May impact connectivity if misconfigured (e.g., restrictive NSG rules or missing routes). ", "remediation": { "text": "#### Remediate from Azure Portal 1. Delete the existing Databricks workspace (migration required). 2. Create a new Databricks workspace with VNet Injection: 3. Go to Azure Portal → Create Databricks Workspace. 4. Select Advanced Networking. 5. Choose Deploy into your own Virtual Network. 6. Specify a customer-managed VNet and associated subnets. 7. Enable Private Link for secure API access.
