4.2 Ensure Data Factory is using Managed Identities (Automated)

Profile Applicability

• Level 1

Description

Managed identities are the roles that Azure services assume to access other services or resources. Access and permissions may be set on these roles to set the scope and reach of what a service can access. Setting a service to use a managed identity also prevents the need to store credentials in code or other less secure options.

Rationale

Managed identities eliminate the need to store and manage credentials to access Azure resources. Scoping permissions of a managed identity to a specific set of resources also prevents unwanted access elsewhere.

Impact

Initial administrative overhead to configure and manage role assignments for managed identities.

Audit

Audit from Azure Portal

1. From Data Factories select a factory to audit.
2. In the left column expand > Settings.
3. Select Managed identities.
4. In the top System assigned menu, determine if the default identity is in use under Status, by whether this is set to On.
5. Determine if there are any custom identities assigned to this resource by selecting in the top menu User Assigned.

Audit From Azure Policy

• Policy ID: f78ccdb4-7bf4-4106-8647-270491d2978a - Name: 'Azure Data Factory linked services should use system-assigned managed identity authentication when it is supported'

Expected Result

The Status under System assigned should be set to On, indicating that a managed identity is in use for the Data Factory.

Remediation

Remediate from Azure Portal

1. From Data Factories select a factory to remediate.
2. In the left column expand > Settings.
3. Select Managed identities.
4. From the System Assigned tab, under select .
