Microsoft Sentinel

Microsoft Sentinel

Microsoft Sentinel is an SIEM integration. SIEM integrations are used to perform analysis of any SIEM generated alerts, and/or to use generated data as part of investigation analysis.

Note that this is different from Microsoft 365/Microsoft Defender.

The Dropzone platform integrates with the Microsoft Sentinel security SIEM. Many customers ingest other alert sources into Microsoft Sentinel (e.g. IDPs) and integrate Dropzone into Microsoft Sentinel rather than the source systems.

Integration Overview

To enable these integrations you will perform the following actions:

• Register a new application in Microsoft Entra Admin

• Locate your Client ID, Tenant ID, and create a Client Secret

• Assign necessary API permissions to the application

• Assign roles to the application in Microsoft Sentinel

• Locate your Workspace Name and Workspace ID

See the Microsoft Integrations page for instructions on how to register a new application, locate your Client ID and Tenant ID, and to create a Client Secret.

Set Application Permissions

General instructions on how to assign API permissions to the application can be found in the Microsoft Integrations page.

Enabling MS Sentinel will require the following APIs and permissions:

API	Permissions
Log Analytics	Data.Read
Microsoft Graph	SecurityEvents.Read.All

To add the Log Analytics API, do the following:

• In the API permissions page, click "Add a permission"

• Navigate to "APIs my organization uses"

• In the search bar, input "Log Analytics API," and select it

Select Log Analytics API

• Click "Application permissions"

• In the search bar, input "Data.Read" and select it. Click "Add permissions"

Add the Data.Read permission

• Once back in the Application API permissions page, click "Grant admin consent for [mycompany.net]"

Grant admin consent

• Click "Yes"

Grant admin consent

If your integration requires access to security alerts via Microsoft Graph, do the following:

• In the API permissions page, click "Add a permission"

• Under the Microsoft API header, select "Microsoft Graph"

Select Microsoft Graph

• Click "Application permissions"

• Check the permission "SecurityEvents.Read.All," then click "Add permissions"

Add the SecurityEvents.Read.All permission

• Once back in the Application API permissions page, click "Grant admin consent for [mycompany.net]"

Grant admin consent

• Click "Yes"

Grant admin consent
