Cis Azure Foundations 5.12

Ensure 'User consent for applications' is set to 'Do not allow user consent'

Description

Require administrators to provide consent for applications before use.

Rationale

If Microsoft Entra ID is running as an identity provider for third-party applications, permissions and consent should be limited to administrators or pre-approved. Malicious applications may attempt to exfiltrate data or abuse privileged user accounts.

Impact

Enforcing this setting may create additional requests that administrators need to review.

Audit Procedure

Using Azure Portal

1. From Azure Home select the Portal Menu
2. Select Microsoft Entra ID
3. Under Manage, select Enterprise applications
4. Under Security, select Consent and permissions
5. Under Manage, select User consent settings
6. Ensure User consent for applications is set to Do not allow user consent

Using PowerShell

Connect-MgGraph
(Get-MgPolicyAuthorizationPolicy).DefaultUserRolePermissions | Select-Object -ExpandProperty PermissionGrantPoliciesAssigned

If the command returns no values in response, the configuration complies with the recommendation.

Expected Result

User consent for applications should be set to Do not allow user consent. The PowerShell command should return no values.
