Change Analysis

The fields in the Change Analysis data model describe Create, Read, Update, and Delete 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 Change Analysis 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
All_Changes	change
|____ Auditing_Changes	audit
|____ Endpoint_Changes	endpoint
|____ Network_Changes	network

Fields for Change Analysis event dataset

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.

Dataset name	Field name	Data type	Description	Expected values
All_Changes	action	string	The action performed on the resource.	created, read, modified, deleted, acl_modified, unknown
All_Changes	change_type	string	The type of change, such as filesystem or AAA (authentication, authorization, and accounting).
All_Changes	command	string	The command that initiated the change.
All_Changes	dest	string	The resource where change occurred. You can alias this from more specific fields, such as dest_host, dest_ip, or dest_name.
All_Changes	dest_bunit	string	These are derived fields provided by Asset and Identity correlation features of certain advanced applications like Splunk Enterprise Security. They should be left blank when writing add-ons.
All_Changes	dest_category	string
All_Changes	dest_priority	string
All_Changes	dvc	string	The device that reported the change, if applicable, such as a FIP or CIM server. You can alias this from more specific fields, such as dvc_host, dvc_ip, or dvc_name.
All_Changes	object	string	Name of the affected object on the resource (such as a router interface, user account, or server volume).
All_Changes	object_attrs	string	The attributes that were updated on the updated resource object, if applicable.
All_Changes	object_category	string	Generic name for the class of the updated resource object. Expected values may be specific to an App.	directory, file, group, object, registry, unknown, user
All_Changes	object_id	string	The unique updated resource object ID as presented to the system, if applicable (for instance, a SID, UUID, or GUID value).
All_Changes	object_path	string	The path of the modified resource object, if applicable (such as a file, directory, or volume).
All_Changes	result	string	The vendor-specific result of a change, or clarification of an action status. For instance, status=failure may be accompanied by result=blocked by policy or result=disk full. Note: result is a string. Please use a msg_severity_id field for severity ID fields that are integer data types.
All_Changes	result_id	string	A result indicator for an action status.
All_Changes	src	string	The resource where the change was originated. You can alias this from more specific fields, such as src_host, src_ip, or src_name.
All_Changes	src_bunit	string	These are derived fields provided by Asset and Identity correlation features of certain advanced applications like Splunk Enterprise Security. They should be left blank when writing add-ons.
All_Changes	src_category	string
All_Changes	src_priority	string
All_Changes	status	string	Status of the update.	success, failure, unknown
All_Changes	tag	string	This automatically generated field is used to access tags from within datamodels. Add-on builders do not need to populate it.
All_Changes	user	string	The user or entity performing the change. For account changes, this is the account that was changed. See src_user for user or entity performing the change.
All_Changes	vendor_product	string	The vendor and product or service that detected the change. This field can be automatically populated by vendor and product fields in your data.
Account_Management	dest_nt_domain	string	The NT domain of the destination, if applicable.
Account_Management	src_nt_domain	string	The NT domain of the source, if applicable.
Account_Management	src_user	string	For account changes, the user or entity performing the change.
Account_Management	src_user_bunit	string	These are derived fields provided by Asset and Identity correlation features of certain advanced applications like Splunk Enterprise Security. They should be left blank when writing add-ons.
Account_Management	src_user_category	string
Account_Management	src_user_priority	string
Filesystem_Changes	file_access_time	time	The time the file (the object of the event) was accessed.
Filesystem_Changes	file_acl	string	Access controls associated with the file affected by the event.
Filesystem_Changes	file_create_time	time	The time the file (the object of the event) was created.
Filesystem_Changes	file_hash	string	A cryptographic identifier assigned to the file object affected by the event.
Filesystem_Changes	file_modify_time	time	The time the file (the object of the event) was altered.
Filesystem_Changes	file_name	string	The name of the file that is the object of the event (without location information related to local file or directory structure).
Filesystem_Changes	file_path	string	The location of the file that is the object of the event, in local file and directory structure terms.
Filesystem_Changes	file_size	number	The size of the file that is the object of the event, in kilobytes.
