Creating a Microsoft Defender XDR connection​

​
Using App Registration​

To create the connection you need:
  • A client ID
  • A client secret
  • A tenant ID

​
Obtaining the credentials​

  1. Log into the Azure Portal.
  2. Go to the Microsoft Entra ID resource. Azure Active Directory Resource
  3. In the left-hand menu, click App registrations. App Registrations
  4. Create a new application registration or click on one of your existing applications. My App
  5. In the left-hand menu, click API permissions. API Permissions
  6. Click Add a permission and select Microsoft Graph. Add Permission
  7. Choose Application permissions and mark the permissions you wish to add. Application Permissions
To support all Blink actions, these are the required application permissions:
As a best practice, request the least privileged permissions that your app needs in order to access data and function correctly. Requesting permissions with more than the necessary privileges is poor security practice, which may cause users to refrain from consenting and affect your app’s usage. For additional information, refer to Microsoft Graph permissions.
