Microsoft Graph Security API Source

The Microsoft Graph Security API Source provides a secure endpoint to receive alerts from the Microsoft Graph Security API endpoint. It securely stores the required authentication, scheduling, and state tracking information. One threat event is reported for each affected device.

Collected data

The Microsoft Graph Security API Source consumes alerts from the Microsoft Graph Security API Endpoint.


A Microsoft Graph Security API Source tracks errors, reports its health, and start-up progress. You’re informed, in real-time, if the Source is having trouble connecting, if there's an error requiring user action, or if it is healthy and collecting by utilizing Health Events.

A Microsoft Graph Security API Source goes through the following states when created:

  1. Pending: Once the Source is submitted it is validated, stored, and placed in a Pending state.
  2. Started: A collection task is created on the Hosted Collector.
  3. Initialized: The task configuration is complete in Sumo Logic.
  4. Authenticated: The Source successfully authenticated with Microsoft.
  5. Collecting: The Source is actively collecting data from Microsoft.

If the Source has any issues during any one of these states it is placed in an Error state.

When you delete the Source it is placed in a Stopping state, when it has successfully stopped it is deleted from your Hosted Collector.

On the Collection page, the Health and Status for Sources is displayed. Use Health Events to investigate issues with collection. You can click the text in the Health column, such as Error, to open the issue in Health Events to investigate.

You need to create and register a service application within the Azure Active Directory portal. The user creating the service application does not need to be an administrator, however, an administrator will be needed to grant the application the appropriate permissions to the Graph Security API.

The following steps show you how to create a service application:

  1. Log into the Azure Active Directory Portal

  2. Select Azure Active Directory in the left menu.

  3. Select App Registrations.

  4. Select New Registration. Go through the registration process, providing a name for the application. Selecting Accounts in this organizational directory only is sufficient.

  5. After the application is registered ensure you copy the Application (client) ID and Directory (tenant) ID displayed on the Overview page. These are needed when creating the Source in Sumo Logic.

  6. Within the application configuration page, select Certificates and Secrets and create an Application Client Secret Key.

  7. Copy the Client Secret value, you'll need it when creating the Source in Sumo Logic.

  8. Request the appropriate permissions for the application. Click on API Permissions, then Add a permission and select Microsoft Graph.

    You need to find and select the SecurityEvents.Read.All permission. See this list of all the available security permissions.


Create a Microsoft Graph Security API Source

When you create a Microsoft Graph Security API Source, you add it to a Hosted Collector. Before creating the Source, identify the Hosted Collector you want to use or create a new Hosted Collector. For instructions, see Configure a Hosted Collector.

To configure a Microsoft Graph Security API Source:

  1. In the Sumo Logic web app, select Manage Data > Collection > Collection
  1. On the Collectors page, click Add Source next to a Hosted Collector.
  1. Select Microsoft Graph Security API.

  1. Enter a Name for the Source. The description is optional.

  1. (Optional) For Source Category, enter any string to tag the output collected from the Source. Category metadata is stored in a searchable field called _sourceCategory.
  2. Forward to SIEM. Check the checkbox to forward your data to Cloud SIEM Enterprise. By default, no metadata fields are set. You can have these set by checking the Set SIEM metadata fields option, in step 9 below.
  1. (Optional) Fields. Click the +Add link to add custom log metadata Fields.
    • Define the fields you want to associate, each field needs a name (key) and value. 
      • green check circle.png A green circle with a check mark is shown when the field exists and is enabled in the Fields table schema.
      • orange exclamation point.png An orange triangle with an exclamation point is shown when the field doesn't exist, or is disabled, in the Fields table schema. In this case, an option to automatically add or enable the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema or is disabled it is ignored, known as dropped.
  2. Enter the Directory (tenant) IDApplication (client) ID, and Application Client Secret Value you got from the Application you created in the prerequisite step.

  3. Set SIEM metadata fields. Check the checkbox to set metadata fields for Cloud SIEM Enterprise. This is beneficial when Microsoft providers are consumed through the Security Graph API. Conversely, when third-party data is consumed, it may be beneficial to not set these fields and instead create a Sumo Logic Ingest Map within CSE to properly set the metadata needed to parse and map your data.

    When checked, the following metadata fields are set:

    Field Name Value
    _siemVendor Security Vendor Information - Vendor
    _siemProduct Security Vendor Information - Provider
    _siemFormat JSON
    _siemEventID msgraph.alert
  4. The Polling Interval is set to 300 seconds by default, you can adjust it based on your needs.

  5. When you are finished configuring the Source click Submit.

Error types

When Sumo Logic detects an issue it is tracked by Health Events. The following table shows the three possible error types, the reason the error would occur, if the Source attempts to retry, and the name of the event log in the Health Event Index.

Type Reason Retries Retry Behavior Health Event Name
ThirdPartyConfig Normally due to an invalid configuration. You'll need to review your Source configuration and make an update. No retries are attempted until the Source is updated. Not applicable ThirdPartyConfigError
ThirdPartyGeneric Normally due to an error communicating with the third party service APIs. Yes The Source will retry for up to 90 minutes, after which retries will be attempted every 60 minutes. ThirdPartyGenericError
FirstPartyGeneric Normally due to an error communicating with the internal Sumo Logic APIs. Yes The Source will retry for up to 90 minutes, after which retries will be attempted every 60 minutes. FirstPartyGenericError

JSON configuration

Sources can be configured using UTF-8 encoded JSON files with the Collector Management API. See how to use JSON to configure Sources for details.
