Article summary

1. About this document

This document provides step-by-step instructions to configure "Azure - Defender for Cloud" (written as "Azure" in this document) in SAFE.

2. Introduction

This integration allows you to onboard assets from Azure and fetch recommendations (referred to as findings in SAFE). SAFE admins can configure this integration from the "Azure - Defender for Cloud" card available on the SAFE Hooks page. Once this integration is configured, SAFE fetches the security misconfiguration detected by Microsoft Defender for Cloud using the Azure Security Center Default policy assignment. This policy assignment depends on the Azure Security Benchmark and utilizes it to quantify cloud-related risks.

  • After a successful configuration, SAFE will automatically onboard the Azure assets. You can view the Azure assets under the "Cloud-Azure" group.
  • SAEF pulls in the MITRE ATT&CK Technique mapping for controls from Azure. 
  • In addition to the auto-sync, SAFE admins can perform an on-demand sync with Azure to pull the assets and misconfigurations.
  • SAFE uses REST APIs provided by Microsoft to consume recommendations data from Microsoft Defender for Cloud. These REST APIs are available at* endpoints. 


3. Prerequisites

  1. Microsoft Defender for Cloud is enabled for your Azure subscriptions.
  2. All subscriptions have the Defender for Cloud default policy enabled. 
  3. The following privileges are needed for a user in Azure to generate the connection details:
    1. For manually creating applications and assigning permissions:
      1. Sufficient privileges/permissions to create an application.
      2. Sufficient privileges/permissions to create a Service Principal account.
      3. Sufficient privileges/permissions to assign the Service Principal account a "Reader" role to the relevant subscriptions.
    2. [Optional] For generating credentials using a script:
      1. Access to the Cloud Shell of your Azure subscription to execute the PowerShell script provided by SAFE.
  4. SAFE access with an admin role.

4. Generate connection details

You have two methods for generating the connection details (Tenant ID, Client ID, and Client Secret):

  1. Manual method by registering an app

4.2 [Alternate Method] Generate connection details via PowerShell Script

You must run a Powershell script on your Azure portal to generate the connection details (Tenant ID, Client ID, and Client Secret). First, download the PowerShell script attached here.

Follow the below step-by-step procedure to generate the connection details:

  1. Login to your Azure portal.
  2. Click the Cloud Shell terminal icon located at the top right corner (refer to the screenshot below).
  3. In the PowerShell terminal, execute the "Connect-AzureAD" command to enable the usage of Active Directory cmdlet requests.
    Powershell script method
  4. Upload the PowerShell script (azureSafeOnboardingScript.ps1) attached above.
    Azure 4(4)
  5. Execute the PowerShell script to create a Service Principal account and assign "Reader" access to subscriptions using one of the following approaches:
    ApproachA: If you want to provide "Reader" access to selected subscriptions for which your current user has privileged access, run the script with the following command-line argument:
    PS /home/user1> ./azureSafeOnboardingScript.ps1 "MySubscription1" "MySubscription2"
    ApproachB: If you want to provide "Reader" access to all subscriptions for which your current user has privileged access, run the script:
    PS /home/user1> ./azureSafeOnboardingScript.ps1
  6. Once the PowerShell script execution is complete, the system creates a Service Principal account named "SAFE-Azure-App" with "Reader" access to all subscriptions.
  7. The system will display the TenantID, ClientID, and ClientSecret. Make sure to copy and save these values for use while configuring Azure in SAFE in the next section.

5. Configure Azure in SAFE

Follow the below steps to configure Azure in SAFE.

  1. Go to the SAFE Hooks and click the "Azure - Defender for Cloud" card.
  2. Enter the TenantID, ClientID, and ClientSecret generated above.
  3. Enter a value for the Auto-SyncFrequency. This controls how often SAFE will synchronize with Azure for the most recent data.
  4. Click the Test Connection button.
  5. Once the connection is validated, click the Save button.
  6. Once the configuration is saved, click the SyncNow button to trigger the on-demand sync outside the scheduled auto sync.
