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 365 Defender.

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

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

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

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

AccountName string User name of the account
AccountSid string Security Identifier (SID) of the account
Protocol string Protocol used during the communication
FailureReason string Information explaining why the recorded action failed
IsLocalAdmin boolean Boolean indicator of whether the user is a local administrator on the machine
LogonId string Identifier for a logon session. This identifier is unique on the same machine only between restarts
RemoteDeviceName string Name of the machine that performed a remote operation on the affected machine. 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

AdditionalFields string Additional information about the event in JSON array format

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.
