New features

Version 4.20.0 of the Splunk Common Information Model Add-on includes the following new features.

Enhancement Description
New Data Access data model. 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. See Data Access.
The Endpoint data model has a new field. The new field in the data model is original_file_name. Certain EDR products include this field to help discover if a file is renamed. See Endpoint.
jQuery 3.5.0 migration. Starting in CIM 4.20.0 to enhance product security, jQuery is migrated from 2.1.0 to 3.5.0 and some Splunk Web Core UI components are deprecated. Library updates have been made that may impact some dashboards with CustomJS.

Upgrade requirements

Splunk platform version Upgrade activity
8.0.x or later If you apply custom tags to data mapped to CIM data models and you use these tags in searches and search filters, add these tags to the whitelists for those models. See Set up the Splunk Common Information Model Add-on for details about the tags whitelist field.
