Cis Azure Database 4.4

4.4 Ensure that Data Factory is using RBAC to manage privilege assignment (Manual)

Profile Applicability

• Level 2

Description

Role Based Access Control (RBAC) is setting permissions to the role that a user occupies. Often the user is added to a group which the account inherits permissions from. This is different than Access Policies which are used on an individual case by case basis for each user.

Rationale

RBAC enhances security by limiting user privilege to only what is necessary for a job role, reducing the risk of unauthorized access. Additionally, RBAC aids compliance with regulations and provides clear accountability by tracking access activities linked to specific roles.

Impact

There will be a slight increase in technical overhead in that user permissions will need to be manually assigned. However once added to a group, permissions may be edited for every account in the group at one time.

Audit

Audit from Azure Portal

1. From Data Factories select a data factory to audit.
2. In the left column select Access control (IAM).
3. To check an individual account or group, in the horizontal row, select Check access, then search for a user, group, or managed identity.
4. To check all roles, in the horizontal row select Role assignments, and scroll through all the roles that have permission to this data factory.

Expected Result

Appropriate RBAC role assignments should be configured for the Data Factory, with roles scoped to the minimum necessary permissions for each user or group.

Remediation

Remediate from Azure Portal

1. From Data Factories select a data factory to audit.
2. In the left column select Access control (IAM).
3. Select + Add \/ and then Add role assignment.

6. Choose Select members, then search for the resource that is to be added to this role.

Default Value

By default, Data factories use RBAC but only with permissions for owners to make changes.
