Featured fields in Cortex XSIAM are specific, predefined attributes used to prominently display the key entities involved in an incident, facilitating quick identification and investigation. According to official Palo Alto Networks documentation, the primary entities highlighted as featured fields include usernames, hostnames, and IP addresses (both source and destination). These fields are consistently displayed in key areas like the Incidents page and the Causality View to streamline the analyst's workflow by allowing for rapid pivoting and context gathering around the core actors and targets of an incident.

A. Device-ID, URL, port, and indicator: While these are valuable data points for an investigation, they are not designated as the primary "featured fields" for incident-level entity summarization in XSIAM.

B. Endpoint-ID, alert source, critical asset, and threat name: These attributes describe the alert or asset properties rather than the core, reusable entities (user, host, IP) that featured fields are designed to highlight across an entire incident.

C. CIDR range, file hash, tags, and log source: These are important for specific queries and context, but they do not serve as the primary featured fields for identifying the main actors and systems in the incident view.

1. Palo Alto Networks, Cortex XSIAM Administrator Guide: In the section "Manage Incident and Alert Fields" -> "Featured Fields", the documentation states, "You can use featured fields to quickly identify the key entities in an incident, such as the users, hosts, and IP addresses involved." It then lists the specific XDM fields that correspond to these entities, including source.user.username, destination.host.hostname, and source.ip. This directly validates that usernames, hostnames, and IP addresses are the intended featured fields. "Active Directory" is the source for much of this identity data.
