Data Access

The Data Access data model is for monitoring shared data access user activity. It helps you detect a user's unauthorized data access, misuse, exfiltration, and more. It applies to events about users accessing data on servers that are shared by many other users, such as: The "file abc" on the "server xyz" was accessed (read, created, modified, shared, and so on) by a "user Bob".

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 Data Access 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.

Fields for Data Access event datasets

The key for using the column titled "Abbreviated list of example values" 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 Data Access Field Mapping.

Dataset name	Field name	Data type	Description	Notes
Data_Access	action	string	The data access action taken by the user.	recommended prescribed values: commented, copied, created, deleted, disabled, downloaded, enabled, granted, forwarded, modified, read, revoked, shared, stopped, uncommented, unlocked, unshared, updated, uploaded,
Data_Access	app	string	The application involved in the event.	recommended
Data_Access	app_id	string	Application ID as defined by the vendor.
Data_Access	dest	string	The destination where the data resides or where it is being accessed, such as the product or application. You can alias this from more specific fields not included in this data model, such as dest_host, dest_ip, dest_url, or dest_name.	recommended
Data_Access	dest_name	string	Name of the destination as defined by the vendor.

Data_Access	object_category	string	Generic name for the class of the updated resource object. Expected values may be specific to an app. For example, collaboration, file, folder, comment, task, note, and so on.	recommended
Data_Access	object_id	string	The unique updated resource object ID as presented to the system, if applicable. For example, a source_folder_id, doc_id.	recommended
Data_Access	object_path	string	The path of the modified resource object, if applicable, such as a file, directory, or volume.
Data_Access	object_size	string	The size of the modified resource object.	recommended
Data_Access	owner	string	Resource owner.
Data_Access	owner_email	string	Email of the resource owner.
Data_Access	owner_id	string	ID of the owner as defined by the vendor.
Data_Access	parent_object	string	Parent of the object name on which the action was performed by a user.
Data_Access	parent_object_id	string	Parent object ID
Data_Access	parent_object_category	string	Object category of the parent object on which action was performed by a user.
Data_Access	signature	string	A human-readable signature name.
Data_Access	signature_id	string	The unique identifier or event code of the event signature.	optional
Data_Access	src	string	The endpoint client host.	recommended
Data_Access	vendor_account	string	Account associated with the event. The account represents the organization, or a Cloud customer or a Cloud account.	recommended
Data_Access	user	string	The user involved in the event, or who initiated the event.	recommended

Data_Access	user_group	string	The group of the user involved in the event, or who initiated the event.
Data_Access	user_id	string	The unique id of the user involved in the event. For authentication privilege escalation events, this should represent the user targeted by the escalation.	optional
Data_Access	user_name	string	The user name of the user or entity performing the change. For account changes, this is the account that was changed (see src_user_name). Use this field for a friendlier name, for example, with AWS events if you do not have Assets and Identities configured in Enterprise Security and are not getting a friendly name from user.	recommended
