Azure security baseline for Data Factory

  • Straipsnis

This security baseline applies guidance from the Microsoft cloud security benchmark version 1.0 to Data Factory. The Microsoft cloud security benchmark provides recommendations on how you can secure your cloud solutions on Azure. The content is grouped by the security controls defined by the Microsoft cloud security benchmark and the related guidance applicable to Data Factory.

You can monitor this security baseline and its recommendations using Microsoft Defender for Cloud. Azure Policy definitions will be listed in the Regulatory Compliance section of the Microsoft Defender for Cloud portal page.

When a feature has relevant Azure Policy Definitions, they are listed in this baseline to help you measure compliance with the Microsoft cloud security benchmark controls and recommendations. Some recommendations may require a paid Microsoft Defender plan to enable certain security scenarios.

Note

Features not applicable to Data Factory have been excluded. To see how Data Factory completely maps to the Microsoft cloud security benchmark, see the full Data Factory security baseline mapping file.

Network security

For more information, see the Microsoft cloud security benchmark: Network security.

NS-1: Establish network segmentation boundaries

Features

Virtual Network Integration

Description: Service supports deployment into customer's private Virtual Network (VNet). Learn more.

Supported Enabled By Default Configuration Responsibility
True False Customer

Feature notes: Azure-SSIS Integration runtime supports virtual network injection on the customer's virtual network. When creating an Azure-SSIS Integration Runtime (IR), you can join it with a virtual network. It will allow Azure Data Factory to create certain network resources, like an NSG and a load balancer. You can also provide your own static public IP address or have Azure Data Factory create one for you. Self-hosted integration runtime (IR) can be set up on IaaS VM within the customer's virtual network. The network traffic is also governed by the customer's NSG and firewall settings.

Configuration Guidance: There is no current Microsoft guidance for this feature configuration. Please review and determine if your organization wants to configure this security feature.

Network Security Group Support

Description: Service network traffic respects Network Security Groups rule assignment on its subnets. Learn more.

Supported Enabled By Default Configuration Responsibility
True False Customer

Feature notes: Azure-SSIS Integration runtime supports virtual network injection on the customer's virtual network. It abides by all NSG and firewall rules set by the customer in their virtual network. When creating an Azure-SSIS Integration Runtime (IR), you can join it with a virtual network. It will allow Azure Data Factory to create certain network resources, like an NSG and a load balancer. You can also provide your own static public IP address or have Azure Data Factory create one for you. On the NSG that is automatically created by Azure Data Factory, Port 3389 is open to all traffic by default. Lock the port down to make sure that only your administrators have access.

Self-hosted integration runtime (IR) can be set up on IaaS VM within the customer's virtual network. The network traffic is also governed by the customer's NSG and firewall settings.

Based on your applications and enterprise segmentation strategy, restrict or allow traffic between internal resources based on your NSG rules. For specific, well-defined applications like a three-tier app, it can be a highly secure deny-by-default.

Configuration Guidance: There is no current Microsoft guidance for this feature configuration. Please review and determine if your organization wants to configure this security feature.

NS-2: Secure cloud services with network controls

Features

Description: Service native IP filtering capability for filtering network traffic (not to be confused with NSG or Azure Firewall). Learn more.

Supported Enabled By Default Configuration Responsibility
True False Customer

Additional Guidance: You can configure private endpoints in the Azure Data Factory Managed Virtual Network to connect to data stores privately.

Data Factory doesn't provide the capability to configure Virtual Network service endpoints.

When you create an Azure-SSIS Integration Runtime (IR), you can join it with a virtual network. It allows Azure Data Factory to create certain network resources, like an NSG and a load balancer. You can also provide your own static public IP address or have Azure Data Factory create one for you. On the NSG that is automatically created by Azure Data Factory, Port 3389 is open to all traffic by default. Lock the port down to ensure that only your administrators have access. You can deploy Self-Hosted IRs on an on-premises machine or Azure VM inside a virtual network. Make sure that your virtual network subnet deployment has an NSG configured to allow only administrative access. Azure-SSIS IR disallows port 3389 outbound by default at the Windows Firewall Rule on each IR node for protection. You can secure your virtual network-configured resources by associating an NSG with the subnet and setting strict rules.

Disable Public Network Access

Description: Service supports disabling public network access either through using service-level IP ACL filtering rule (not NSG or Azure Firewall) or using a 'Disable Public Network Access' toggle switch. Learn more.

Supported Enabled By Default Configuration Responsibility

Feature notes: You can use Windows authentication to access data sources from SSIS packages running on Azure-SSIS Integration Runtime (IR). Your data stores can be on premises, hosted on Azure Virtual Machines (VMs), or running in Azure as managed services. However, we recommend avoiding the usage of local authentication and using Azure AD wherever possible. Avoid the usage of local authentication methods or accounts, these should be disabled wherever possible. Instead use Azure AD to authenticate where possible.

Description: Azure Role-Based Access Control (Azure RBAC) can be used to managed access to service's data plane actions. Learn more.

Supported Enabled By Default Configuration Responsibility
True True Microsoft

Feature notes: Data Factory integrates with Azure RBAC to manage its resources. With RBAC, you manage Azure resource access through role assignments. You can assign roles to users, groups, service principals, and managed identities. Certain resources have pre-defined, built-in roles. You can inventory or query these roles through tools like Azure CLI, Azure PowerShell, or the Azure portal.

Limit the privileges you assign to resources through Azure RBAC to what the roles require. This practice complements the just-in-time (JIT) approach of Azure AD PIM. Review roles and assignments periodically.

Use built-in roles to give permissions. Only create custom roles when required.

You can create a custom role in Azure AD with more restrictive access to Data Factory.

Configuration Guidance: No additional configurations are required as this is enabled on a default deployment.
