# Ensure 'Tenant Creator' role assignments are periodically reviewed

## Description

Perform a periodic review of the Tenant Creator role assignment to ensure that the assignments are accurate and appropriate.

This recommendation should be applied alongside the recommendation **"Ensure that 'Restrict non-admin users from creating tenants' is set to 'Yes'"**.

## Rationale

Unnecessary assignments increase the risk of privilege escalation and unauthorized access.

## Impact

Verify that the Tenant Creator role is no longer required by any assignments before removal to avoid disruption of critical functions.

## Audit Procedure

### Using Azure Portal

1. Go to `Microsoft Entra ID`.
2. Under `Manage`, click `Roles and administrators`.
3. In the search bar, type `Tenant Creator`.
4. Click the role.
5. Review the assignments and ensure that they are appropriate.

## Expected Result

The Tenant Creator role should have no unnecessary assignments. All assignments should be justified and documented.

## Remediation

### Remediate from Azure Portal

1. Go to `Microsoft Entra ID`.
2. Under `Manage`, click `Roles and administrators`.
3. In the search bar, type `Tenant Creator`.
4. Click the role.
5. Click the name of an assignment.
6. Check the box next to the `Tenant Creator` role.
7. Click `X Remove assignments`.
8. Click `Yes`.
9. Repeat steps 1-8 for each assignment requiring remediation.

## Default Value

The Tenant Creator role is not assigned by default.
