Supported data sources in behavioral analytics service

This topic applies only to customers on the Splunk Cloud platform.

Behavioral analytics service uses data sources to generate anomalies.

The following table identifies the source types supported by universal forwarders:

Data source Sourcetype for universal forwarder
Windows security logs XmlWinEventLog:Security


Windows event IDs supported in Splunk Behavioral Analytics

The following table summarizes the Microsoft Windows event IDs used by behavioral analytics service. See Configure Windows event logging to ensure the proper events are logged for instructions to properly log Microsoft Windows events.

Event ID Description Supported for XmlWinEventLog
4103 Windows license activation failed Yes
4104 PowerShell script block logging Yes
4624 An account was successfully logged on Yes
4625 An account failed to log on Yes
4661 A handle to an object was requested Yes
4662 An operation was performed on an object Yes
4663 An attempt was made to access an object Yes
4673 A privileged service was called Yes
4688 A new process has been created Yes
4689 A process has exited Yes
5145 A network share object was checked to see whether client can be granted desired access Yes


Data source sample events and fields mappings

Behavioral analytics service extracts and maps the values from specific fields in each data source to be used by its models. Expand each Fields and Mapping section to see how fields in raw events are mapped. The tables in the Field and Mapping section contain the following information:

Table column Description
Raw event field name The original value of the field in the raw event.
Behavioral analytics service token name What the field in the raw event is mapped to in behavioral analytics service. For example, the raw event may contain a field named threatURL, but the models in behavioral analytics service require a field named threat_url.
Behavioral analytics service entity/field type The field used to enrich entities with assets and identities data. For example, a local_ip field in the raw event marked as dest_user/DNS in the table defines the database table used to perform the lookup, so DNS addresses are searched when performing the lookup instead of IP tables.
Behavioral analytics service data model Data models in behavioral analytics service normalize data into specific categories like Authorization or Endpoint. The detections in the system run queries against this normalized data instead of running vendor-specific queries.
