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 "Abbreviated list of example values" follows:

• Recommended are fields derived from the "recommended=true" JSON parameter that the TA developers need to make best efforts to map
• Prescribed fields are the permitted values that can populate the fields, which are derived from the "expected_values" JSON parameter
• Other values are other example values that you might see

Dataset name	Field name	Data type	Description	Abbreviated list of example values
Authentication	action	string	The action performed on the resource.	recommended prescribed fields: success, failure
Authentication	app	string	The application involved in the event.	recommended other: ssh, splunk, win:local
Authentication	dest	string	The target involved in the authentication. You can alias this from more specific fields, such as dest_host, dest_ip, or 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, such as email_server or SOX-compliant. 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_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	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, such as 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, such as email_server or SOX-compliant. 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_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_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	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 name 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.	recommended
Authentication	user_bunit	string	The business unit 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.
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.
Authentication	user_priority	string	The priority 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.
