Splunk UBA category to Splunk CIM field reference

When adding CIM-compliant data to Splunk UBA, the field names from the data source must match the field names expected by Splunk UBA. Mapping the data source field names to the field names expected by Splunk UBA happens automatically when possible, but is not always possible. In those cases, you can use these tables to map the fields in Splunk UBA. See Use connectors to add data from the Splunk platform to Splunk UBA.

Do not make changes to the tags, eventtypes, or data in the Splunk platform.

Splunk UBA categories and corresponding CIM data models

Splunk UBA categories rely on the tags from CIM-compliant events to correctly parse data from the Splunk platform. Review this table to determine which category in Splunk UBA corresponds to the CIM data model that the events in the Splunk platform are mapped to. Click the name of the Splunk UBA category to review the field mappings between Splunk UBA and the CIM data models.

The tags in the table have an implied AND and are evaluated as follows:

• Categories that require a single tag such as Authentication will evaluate based on that tag. For example, authentication events must have tag=authentication to be parsed by Splunk UBA. Splunk UBA generates error messages when the percentage of valid events drops below a specific threshold.
• Categories with multiple tags such as DHCP have an implied AND among the tags, and are evaluated using a combination of all tags. For example, DHCP events must have all three of tag=network, tag=session, tag=dhcp to be parsed by Splunk UBA. Splunk UBA generates error messages when the combined percentage of valid events falls below a specific threshold.

VPN category

The VPN category for Splunk UBA maps to the VPN dataset of the Network Sessions data model, and to the Network Traffic data model.

Every category requires a tag field. All CIM-compliant data contains at least one tag field that indicates the data model mapping. Splunk UBA requires the following tag combinations to process VPN category events:

• To properly parse when VPN connections are initiated, Splunk UBA requires tag=network, tag=session, tag=vpn, tag=start.
• To properly parse traffic flow in a VPN connection, Splunk UBA requires tag=network, tag=session, tag=vpn.
• To properly parse when VPN connections are terminated, Splunk UBA requires tag=network, tag=session, tag=vpn, tag=end.
