Secure Application Model

[アーティクル]
03/21/2019

Microsoft is introducing a secure framework for authenticating Cloud Solution Provider (CSP) partners and Control Panel Vendors (CPV) using multi-factor authentication (MFA). This new model will elevate security for operations involving the Partner Center API. This will help to protect the partner’s infrastructure and customer data from security risk. To learn more about the secure application model read through the Enable secure application model documentation. This article will demonstrate how to utilize the Partner Center PowerShell module with the secure application model.

Partners will need to perform a consent process. Through this process, an access token will be requested from Azure Active Directory using an authorization code. The result returned from that request will include an access token, refresh token and additional information. The refresh token value should be stored in a secure repository such as Azure Key Vault. It will be used when requesting an access token to interact with the Partner Center API. You can use the New-PartnerAccessToken command to perform the consent process.

Note: When using New-PartnerAccessToken for Azure clouds such as US Government, environment parameter to be populated with values as defined in the module documentation. Failing to set explicit environment parameter will default the environment Global Azure and could result in the powershell to return error "AADSTS90038: Confidential Client is not supported in Cross Cloud request."

Azure AD Application

An Azure AD application will be required to perform the consent operation. The Azure AD application must have urn:ietf:wg:oauth:2.0:oob configured as on the reply URLs. You can use the following PowerShell commands to configure the reply address for an existing application.

Import-Module AzureAD
Set-AzureADApplication -ObjectId '<Object-Id-Of-Your-App>' -ReplyUrls @("urn:ietf:wg:oauth:2.0:oob")

If you rather create a new application, then the following PowerShell script can be used to create and configure the required Azure AD application

<#
    .SYNOPSIS
        This script will create the require Azure AD application.
    .EXAMPLE
        .\Create-AzureADApplication.ps1 -ConfigurePreconsent -DisplayName "Partner Center Web App"

        .\Create-AzureADApplication.ps1 -ConfigurePreconsent -DisplayName "Partner Center Web App" -TenantId aaaabbbb-0000-cccc-1111-dddd2222eeee

        .\Create-AzureADApplication.ps1 -ConfigurePreconsent -DisplayName "Partner Center Web App" -TenantId tenant01.onmicrosoft.com
    .PARAMETER ConfigurePreconsent
        Flag indicating whether or not the Azure AD application should be configured for preconsent.
    .PARAMETER DisplayName
        Display name for the Azure AD application that will be created.
    .PARAMETER TenantId
        [OPTIONAL] The domain or tenant identifier for the Azure AD tenant that should be utilized to create the various resources.

}

$adAppAccess = [Microsoft.Open.AzureAD.Model.RequiredResourceAccess]@{
    ResourceAppId = "00000002-0000-0000-c000-000000000000";
    ResourceAccess =

}

$partnerCenterAppAccess = [Microsoft.Open.AzureAD.Model.RequiredResourceAccess]@{

}

$SessionInfo = Get-AzureADCurrentSessionInfo

Write-Host -ForegroundColor Green "Creating the Azure AD application and related resources..."

$app = New-AzureADApplication -AvailableToOtherTenants $true -DisplayName $DisplayName -IdentifierUris "https://$($SessionInfo.TenantDomain)/$((New-Guid).ToString())" -RequiredResourceAccess $adAppAccess, $graphAppAccess, $partnerCenterAppAccess -ReplyUrls @("urn:ietf:wg:oauth:2.0:oob")

if($ConfigurePreconsent) {

    Add-AzureADGroupMember -ObjectId $adminAgentsGroup.ObjectId -RefObjectId $spn.ObjectId
}

Write-Host "ApplicationId       = $($app.AppId)"
Write-Host "ApplicationSecret   = $($password.Value)"

Next you will need to invoke the New-PartnerAccessToken command as shown below to perform the consent process.

$credential = Get-Credential
$token = New-PartnerAccessToken -Consent -Credential $credential -Resource https://api.partnercenter.microsoft.com -TenantId '<Your Tenant Id>'

When the command is invoked, you will be prompted to enter a username and password. Specify the application identifier as the username and the application secret as the password. When then New-PartnerAccessToken command is invoked, you will be prompted for credentials once again. This time you will need to specify the credentials for the service account that you will be using. The service account should be a partner account with the appropriate permissions. After the successful execution of the command, you will find that the $token variable contains the response from Azure Active Directory for a token. In the response is a refresh token, you will want to store this value in a secure repository such as Azure Key Vault or a similar service.

Using the Refresh Token

Using the Connect-PartnerCenter command you can connect to Partner Center. You will need to obtain the refresh token value from the secure repository where you stored it. Execute the following commands to request an access token and use it when connecting to Partner Center.

$refreshToken = 'Enter the refresh token value here'

$credential = Get-Credential
$tenantId = '<Your Tenant Id>'
$pcToken = New-PartnerAccessToken -RefreshToken $refreshToken -Resource https://api.partnercenter.microsoft.com -Credential $credential -TenantId $tenantId

Connect-PartnerCenter -AccessToken $pcToken.AccessToken -TenantId $tenantId

When you are prompted for credentials specify the application identifier and application secret, for the Azure AD application used when generating the refresh token.

Azure

The Az and AzureRM PowerShell modules both support the ability to authenticate using access tokens. The following commands demonstrate how to utilize a refresh token to obtain the required access token to connect using the Connect-AzAccount or Connect-AzureRmAccount commands.

$credential = Get-Credential
$refreshToken = 'Your-Refresh-Token-Value'

$azureToken = New-PartnerAccessToken -RefreshToken $refreshToken -Resource https://management.azure.com/ -Credential $credential -TenantId '<Your Tenant Id>'
$graphToken =  New-PartnerAccessToken -RefreshToken $refreshToken -Resource https://graph.microsoft.com -Credential $credential -TenantId '<Your Tenant Id>'

# Az Module
Connect-AzAccount -AccessToken $azureToken.AccessToken -GraphAccessToken $graphToken.AccessToken -TenantId '<TenantId>'

# AzureRM Module
Connect-AzureRmAccount -AccessToken $azureToken.AccessToken -GraphAccessToken $graphToken.AccessToken -TenantId '<TenantId>'

MSOnline

The MSOnline PowerShell module support authentication using access tokens. The following commands demonstrate how to utilize the refresh token to obtain the required access token to connect using the Connect-MsolService command.

$credential = Get-Credential
$refreshToken = 'Your-Refresh-Token-Value'

$aadGraphToken = New-PartnerAccessToken -RefreshToken $refreshToken -Resource https://graph.windows.net -Credential $credential -TenantId '<Your Tenant Id>'
$graphToken =  New-PartnerAccessToken -RefreshToken $refreshToken -Resource https://graph.microsoft.com -Credential $credential -TenantId '<Your Tenant Id>'

Connect-MsolService -AdGraphAccessToken $aadGraphToken.AccessToken -MsGraphAccessToken $graphToken.AccessToken
