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
-
Log into the Azure Portal.
-
Go to the Microsoft Entra ID resource.

In the left-hand menu, click App registrations.

In the left-hand menu, click API permissions.
-
Click Add a permission and select Microsoft Graph.
-
Choose Application permissions and mark the permissions you wish to add.
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.
| Least privileged permissions | Higher privileged permissions |
|---|---|
| SecurityAlert.Read.All | SecurityAlert.ReadWrite.All |
| SecurityIncident.Read.All | SecurityIncident.ReadWrite.All |
| SecurityAlert.ReadWrite.All | |
| SecurityIncident.ReadWrite.All |
