Connect data from Microsoft 365 Defender to Azure Sentinel

Important

Microsoft 365 Defender was formerly known as Microsoft Threat Protection or MTP.

Microsoft Defender for Endpoint was formerly known as Microsoft Defender Advanced Threat Protection or MDATP.

You may see the old names still in use for a period of time.

Background

Azure Sentinel's Microsoft 365 Defender (M365D) connector with incident integration allows you to stream all M365D incidents and alerts into Azure Sentinel, and keeps the incidents synchronized between both portals. M365D incidents include all their alerts, entities, and other relevant information, and they are enriched by and group together alerts from M365D's component services Microsoft Defender for Endpoint, Microsoft Defender for Identity, Microsoft Defender for Office 365, and Microsoft Cloud App Security.

The connector also lets you stream advanced hunting events from Microsoft Defender for Endpoint into Azure Sentinel, allowing you to copy Defender for Endpoint advanced hunting queries into Azure Sentinel, enrich Sentinel alerts with Defender for Endpoint raw event data to provide additional insights, and store the logs with increased retention in Log Analytics.

For more information about incident integration and advanced hunting event collection, see Microsoft 365 Defender integration with Azure Sentinel.

Important

The Microsoft 365 Defender connector is currently in PREVIEW. See the Supplemental Terms of Use for Microsoft Azure Previews for additional legal terms that apply to Azure features that are in beta, preview, or otherwise not yet released into general availability.

Prerequisites

  • You must have a valid license for Microsoft 365 Defender, as described in Microsoft 365 Defender prerequisites.

  • You must be a global administrator or a security administrator in Azure Active Directory.

Connect to Microsoft 365 Defender

  1. In Azure Sentinel, select Data connectors, select Microsoft 365 Defender (Preview) from the gallery and select Open connector page.

  2. Under Configuration in the Connect incidents & alerts section, click the Connect incidents & alerts button.

  3. To avoid duplication of incidents, it is recommended to mark the check box labeled Turn off all Microsoft incident creation rules for these products.

    Note

    When you enable the Microsoft 365 Defender connector, all of the M365D components’ connectors (the ones mentioned at the beginning of this article) are automatically connected in the background. In order to disconnect one of the components’ connectors, you must first disconnect the Microsoft 365 Defender connector.

  4. To query Microsoft 365 Defender incident data, use the following statement in the query window:

    SecurityIncident
    | where ProviderName == "Microsoft 365 Defender"
    
  5. If you want to collect advanced hunting events from Microsoft Defender for Endpoint, the following types of events can be collected from their corresponding advanced hunting tables.

    1. Mark the check boxes of the tables with the event types you wish to collect:

      Table name Events type
      DeviceInfo Machine information (including OS information)
      DeviceNetworkInfo Network properties of machines
      DeviceProcessEvents Process creation and related events
      DeviceNetworkEvents Network connection and related events
      DeviceFileEvents File creation, modification, and other file system events
      DeviceRegistryEvents Creation and modification of registry entries
      DeviceLogonEvents Sign-ins and other authentication events
      DeviceImageLoadEvents DLL loading events
      DeviceEvents Additional events types
      DeviceFileCertificateInfo Certificate information of signed files
    2. Click Apply Changes.

    3. To query the advanced hunting tables in Log Analytics, enter the table name from the list above in the query window.

Verify data ingestion

The data graph in the connector page indicates that you are ingesting data. You'll notice that it shows one line each for incidents, alerts, and events, and the events line is an aggregation of event volume across all enabled tables. Once you have enabled the connector, you can use the following KQL queries to generate more specific graphs.

Use the following KQL query for a graph of the incoming Microsoft 365 Defender incidents:

let Now = now(); 
(range TimeGenerated from ago(14d) to Now-1d step 1d 
| extend Count = 0 
| union isfuzzy=true ( 
    SecurityIncident
    | where ProviderName == "Microsoft 365 Defender"
    | summarize Count = count() by bin_at(TimeGenerated, 1d, Now) 
) 
| summarize Count=max(Count) by bin_at(TimeGenerated, 1d, Now) 
| sort by TimeGenerated 
| project Value = iff(isnull(Count), 0, Count), Time = TimeGenerated, Legend = "Events") 
| render timechart 

Use the following KQL query to generate a graph of event volume for a single table (change the DeviceEvents table to the required table of your choosing):

let Now = now();
(range TimeGenerated from ago(14d) to Now-1d step 1d
| extend Count = 0
| union isfuzzy=true (
    DeviceEvents
    | summarize Count = count() by bin_at(TimeGenerated, 1d, Now)
)
| summarize Count=max(Count) by bin_at(TimeGenerated, 1d, Now)
| sort by TimeGenerated
| project Value = iff(isnull(Count), 0, Count), Time = TimeGenerated, Legend = "Events")
| render timechart

In the Next steps tab, you’ll find some useful workbooks, sample queries, and analytics rule templates that have been included. You can run them on the spot or modify and save them.
