Authentication

The fields and tags in the Authentication data model describe login activities from any data source.

Note: A dataset is a component of a data model. In versions of the Splunk platform prior to version 6.5.0, these were referred to as data model objects.

Tags used with Authentication event datasets

The following tags act as constraints to identify your events as being relevant to this data model. For more information, see How to use these reference tables.

Dataset name	Tag name
Authentication	authentication
|____ Default_Authentication	default
|____ Insecure_Authentication	cleartext OR insecure
|____ Privileged_Authentication	privileged

Fields for Authentication event datasets

The following table lists the extracted and calculated fields for the event datasets in the model. The table does not include any inherited fields. For more information, see How to use these reference tables.

The key for using the column titled "Notes" or "Abbreviated list of example values" is as follows:

• Recommended: Add-on developers make their best effort attempts to map these event fields. If these fields are not populated, then the event is not very useful.
• Required: Add-on developers must map these event fields when using the pytest-splunk-addon to test for CIM compatibility. See pytest-splunk-addon documentation.
• Prescribed values: Permitted values that can populate the fields, which Splunk is using for a particular purpose. Other valid values exist, but Splunk is not relying on them.
• Other values: Other example values that you might see.

For even more examples, see Authentication Field Mapping.

Dataset name	Field name	Data type	Description	Notes
Authentication	action	string	The action performed on the resource.	Prescribed values: success, failure, pending, error Recommended. Also, required for pytest-splunk-addon
Authentication	app	string	The application involved in the event.	ssh splunk win:local signin.amazonaws.com Recommended. Also, required for pytest-splunk-addon
Authentication	authentication_method	string	The method used to authenticate the request.	Optional
Authentication	authentication_service	string	The service used to authenticate the request.	Okta, ActiveDirectory, AzureAD Optional
Authentication	dest	string	The target host involved in the authentication. You can alias this from more specific fields.	dest_host, dest_ip, dest_nt_host Recommended
Authentication	dest_bunit	string	The business unit of the authentication target.	This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
Authentication	dest_category	string	The category of the authentication target.	This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons. email_server or SOX-compliant
Authentication	dest_nt_domain	string	The name of the Active Directory used by the authentication target, if applicable.
Authentication	dest_priority	string	The priority of the authentication target.	This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
Authentication	duration	number	The amount of time for the completion of the authentication event, in seconds.
Authentication	reason	string	The human-readable message associated with the authentication action (success or failure). Used when differentiating from event name (signature). Often used to describe the reason of the logon failure, such as "wrong password"".
Authentication	response_time	number	The amount of time it took to receive a response in the authentication event, in seconds.
Authentication	signature	string	A human-readable signature name.
Authentication	signature_id	string	The unique identifier or event code of the event signature.
Authentication	src	string	The source involved in the authentication. In the case of endpoint protection authentication the src is the client.	You can alias this from more specific fields. src_host, src_ip, or src_nt_host. Do not confuse src with the event source or sourcetype fields. Recommended
Authentication	src_bunit	string	The business unit of the authentication source.	This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
Authentication	src_category	string	The category of the authentication source.	email_server or SOX-compliant
Authentication	src_nt_domain	string	The name of the Active Directory used by the authentication source, if applicable.
Authentication	src_priority	string	The priority of the authentication source.	This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
Authentication	src_user	string	In privilege escalation events, src_user represents the user who initiated the privilege escalation.	This field is unnecessary when an escalation has not been performed. Recommended
Authentication	src_user_bunit	string	The business unit of the user who initiated the privilege escalation.	This field is unnecessary when an escalation has not been performed. This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
Authentication	src_user_category	string	The category of the user who initiated the privilege escalation.	This field is unnecessary when an escalation has not been performed.This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
Authentication	src_user_id	string	The unique id of the user who initiated the privilege escalation.	This field is unnecessary when an escalation has not been performed.
Authentication	src_user_priority	string	The priority of the user who initiated the privilege escalation.	This field is unnecessary when an escalation has not been performed. This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
Authentication	src_user_role	string	The role of the user who initiated the privilege escalation.	This field is unnecessary when an escalation has not been performed.
Authentication	src_user_type	string	The type of the user who initiated the privilege escalation.	This field is unnecessary when an escalation has not been performed.
Authentication	tag	string	This automatically-generated field is used to access tags from within data models.	Do not define extractions for this field when writing add-ons.
Authentication	user	string	The actual string or identifier that a user is logging in with.	This is the user involved in the event, or who initiated the event. For authentication privilege escalation events, this should represent the user string or identifier targeted by the escalation. Recommended. Also, required for pytest-splunk-addon
Authentication	user_agent	string	The user agent through which the request was made. Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) or aws-cli/2.0.0 Python/3.7.4 Darwin/18.7.0 botocore/2.0.0dev4
Authentication	user_bunit	string	The business unit of the user involved in the event, or who initiated the event.

This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
Authentication	user_category	string	The category of the user involved in the event, or who initiated the event.	For authentication privilege escalation events, this should represent the user targeted by the escalation. This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this field when writing add-ons.
