  • Raksts

Applies to:

  • Microsoft Defender XDR
  • Microsoft Defender for Endpoint

The DeviceLogonEvents table in the advanced hunting schema contains information about user logons and other authentication events on devices. Use this reference to construct queries that return information from this table.

Tip

For detailed information about the events types (ActionType values) supported by a table, use the built-in schema reference available in Microsoft Defender XDR.

For information on other tables in the advanced hunting schema, see the advanced hunting reference.

DeviceId string Unique identifier for the device in the service
DeviceName string Fully qualified domain name (FQDN) of the device
ActionType string Type of activity that triggered the event
LogonType string Type of logon session, specifically:

- Interactive - User physically interacts with the device using the local keyboard and screen

- Remote interactive (RDP) logons - User interacts with the device remotely using Remote Desktop, Terminal Services, Remote Assistance, or other RDP clients

- Batch - Session initiated by scheduled tasks

- Service - Session initiated by services as they start

AccountName string User name of the account
AccountSid string Security Identifier (SID) of the account

RemoteDeviceName string Name of the device that performed a remote operation on the affected device. Depending on the event being reported, this name could be a fully-qualified domain name (FQDN), a NetBIOS name or a host name without domain information.
RemoteIP string IP address of the device from which the logon attempt was performed
RemoteIPType string Type of IP address, for example Public, Private, Reserved, Loopback, Teredo, FourToSixMapping, and Broadcast

InitiatingProcessParentFileName string Name or full path of the parent process that spawned the process responsible for the event
InitiatingProcessParentCreationTime datetime Date and time when the parent of the process responsible for the event was started
ReportId long Event identifier based on a repeating counter. To identify unique events, this column must be used in conjunction with the DeviceName and Timestamp columns.
AppGuardContainerId string Identifier for the virtualized container used by Application Guard to isolate browser activity
AdditionalFields string Additional information about the event in JSON array format
InitiatingProcessSessionId long Windows session ID of the initiating process
IsInitiatingProcessRemoteSession bool Indicates whether the initiating process was run under a remote desktop protocol (RDP) session (true) or locally (false)
InitiatingProcessRemoteSessionDeviceName string Device name of the remote device from which the initiating process’s RDP session was initiated
InitiatingProcessRemoteSessionIP string IP address of the remote device from which the initiating process’s RDP session was initiated

Note

The collection of DeviceLogonEvents is not supported on Windows 7 or Windows Server 2008R2 devices onboarded to Defender for Endpoint. We recommend upgrading to a more recent operating system for optimal visibility into user logon activity.
