A security analyst wants to prioritize incidents by highlighting critical cases that require immediate executive visibility. Which feature should the analyst use to flag these specific incidents in the Incident View?

AIncident scoring threshold override
BData stitching rule assignment
Incident starringCorrect
DFeatured fields configuration

Incident starring in Cortex XDR is a manual flag that analysts apply to specific incidents to mark them as noteworthy — for example, for executive visibility or follow-up. Starred incidents can be filtered and surfaced in dashboards, making them easy to track. This is the intende…Read full explanation

Q2Alert Lifecycle And Incident Correlationhard

While investigating an alert in Cortex XDR, an analyst notices that a network-layer alert and an endpoint-layer alert have not been stitched into the same incident despite sharing the same internal IP address and user account. What is the most likely cause of this behavior?

AThe incident score was manually overridden to low
BAlert starring was disabled on the network data source
CFeatured fields were not configured for the network logs
The time delta between the endpoint and network events exceeds the stitching correlation windowCorrect

Cortex XDR stitches alerts into incidents by correlating on shared featured fields (such as IP, user, hostname) within a defined time window. If the endpoint event and the network event occur too far apart in time, the correlation engine will not merge them, so they appear as sep…Read full explanation

Q3Alert Lifecycle And Incident Correlationhard
Full explanation →

During the raw-alert-to-incident lifecycle, an alert is generated by a custom BIOC (Behavioral Indicator of Compromise). At what point does this raw alert transition into an actionable incident?

Immediately upon correlation and grouping by the Incident EngineCorrect
BOnly after an analyst manually assigns a severity score
COnce featured fields are populated for the data source
DWhen the alert is starred by a tier-2 analyst

When a raw alert triggers, Cortex XDR evaluates it against existing open incidents or creates a new incident based on correlation and stitching logic, moving it into the Incident View.
