Collect Microsoft Azure AD logs

This document describes how you can collect Microsoft Azure Active Directory (AD) logs by setting up a Google Security Operations feed.

Azure Active Directory ( AZURE_AD ) is now called Microsoft Entra ID. Azure AD audit logs ( AZURE_AD_AUDIT ) are now Microsoft Entra ID audit logs.

For more information, see Data ingestion to Google Security Operations .

An ingestion label identifies the parser which normalizes raw log data to structured UDM format.

Before you begin

Ensure you have the following prerequisites:

• An Azure subscription that you can sign in to
• A global administrator or Azure AD administrator role
• An Azure AD (tenant) in Azure

How to configure Azure AD

1. Sign in to the Azure portal.
2. Go to Home > App registration, select a registered application or register an application if you haven't created an application yet.
3. To register an application, in the App registrationsection, click New registration.
4. In the Namefield, provide the display name for your application.
5. In the Supported account typessection, select the required option to specify who can use the application or access the API.
6. Click Register.
7. Go to the Overviewpage and copy the application (client) ID and the directory (tenant) ID, which are required to configure the Google Security Operations feed.
8. Click API permissions.
9. Click Add a permission, and then select Microsoft Graphin the new pane.
10. Click Application permissions.
11. Select AuditLog.Read.All, Directory.Read.All, and SecurityEvents.Read.Allpermissions. Ensure that the permissions are Application permissionsand not Delegated permissions.
12. Click Grant admin consent for default directory. Applications are authorized to call APIs when they are granted permissions by users or administrators as part of the consent process.
13. Go to Settings > Manage.
14. Click Certificates and secrets.
15. Click New client secret. In the Valuefield, the client secret appears.
16. Copy the client secret value. The value is displayed only at the time of creation and it is required for the Azure app registration and to configure the Google Security Operations feed.

Set up feeds

There are two different entry points to set up feeds in the Google SecOps platform:

• SIEM Settings > Feeds > Add New Feed
• Content Hub > Content Packs > Get Started

How to set up the Microsoft Entra ID (Azure AD) feed

1. Click the Azure Platformpack.
2. Locate the Azure ADlog type.

3. Specify values for the following fields:

   • Source Type: Third party API (recommended)
   • OAUTH client ID: Specify the client ID that you obtained previously.
   • OAUTH client secret: Specify the client secret that you obtained previously.
   • Tenant ID: Specify the tenant ID that you obtained previously.
   • API Full path: Microsoft Graph REST API endpoint URL.
   • API Authentication Endpoint: Microsoft Active Directory Authentication Endpoint.

   Advanced Options

   • Feed Name: A prepopulated value that identifies the feed.
   • Asset Namespace: Namespace associated with the feed .
   • Ingestion Labels: Labels applied to all events from this feed.

4. Click Create feed.

For more information about configuring multiple feeds for different log types within this product family, see Configure feeds by product .

Field mapping reference

This parser code transforms raw Azure AD logs in JSON format into a unified data model (UDM). It first normalizes the data by removing unnecessary fields and then extracts relevant information like user details, timestamps, and event specifics, mapping them to corresponding UDM fields for consistent representation and analysis.
