Event Signatures

Event Signatures is a standard location to store Windows EventID. This data model is searchable as DataModel.DataSet. It is not accelerated by default, but the appropriate acceleration settings have been defined.

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.

Dataset name	Tag name
Event_Signatures
|____ Signatures	track_event_signatures

The following table lists the extracted and calculated fields for the event datasets in the model. Note that it 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.

Event Signatures

Dataset name	Field name	Data type	Description	Abbreviated list of example values
Signatures	dest	string	System affected by the signature.
Signatures	dest_bunit	string	This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this fields when writing add-ons.
Signatures	dest_category	string	This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this fields when writing add-ons.
Signatures	dest_priority	string	This field is automatically provided by asset and identity correlation features of applications like Splunk Enterprise Security. Do not define extractions for this fields when writing add-ons.
Signatures	signature	string	The human readable event name.
Signatures	signature_id	string	The event name identifier (as supplied by the vendor).
Signatures	tag	string	This automatically generated field is used to access tags from within data models. Add-on builders do not need to populate it.

Calculations

Calculation ID	Field name	Data type	Description	Abbreviated list of example values
Signatures_vendor_product	vendor_product	string	The vendor and product name of the technology that reported the event, such as Carbon Black Cb Response. This field can be automatically populated by vendor and product fields in your data. Expression: case(isnotnull(vendor_product),vendor_product, isnotnull(vendor) AND vendor!=\"unknown\" AND isnotnull(product) AND product!=\"unknown\",vendor.\" \".product,isnotnull(vendor) AND vendor!=\"unknown\" AND (isnull(product) OR product=\"unknown\"),vendor.\" unknown\",(isnull(vendor) OR vendor=\"unknown\") AND isnotnull(product) AND product!=\"unknown\",\"unknown \".product,isnotnull(sourcetype),sourcetype, 1=1,\"unknown\")"	recommended
