Question 850
A security operations shift handoff reports this condition: A high-confidence detection appears in Event Monitor, but the incident queue remains empty despite the team expecting a new case. Which condition best explains this security analytics result?
Explanation
Correct Answer
The underlying principle is: An event generated by an event handler does not automatically become an incident unless the relevant incident-creation setting or workflow is enabled. Address this by: Enable the supported Automatically Create Incident option for the appropriate high-confidence event handler. The confirming operational observation is: A new qualifying test event creates a related incident with traceable event evidence.
Incorrect Answers
Absence of new alerts is not equivalent to verified recovery when logging or malicious activity may have stopped temporarily. “Review linked evidence, containment actions and independent remediation checks before moving the incident to closed state” would remedy that alternative situation, but it would not correct the present issue: an event generated by an event handler does not automatically become an incident unless the relevant incident-creation setting or workflow is enabled.
“Link related events and, where appropriate, consolidate into a single case with separate supporting indicators” is the supported response when overlapping detections may describe one underlying host investigation rather than independent incidents. Here the decisive response is “Enable the supported Automatically Create Incident option for the appropriate high-confidence event handler”, so that different intervention does not meet the stated requirement.
A case without evidence-backed affected-asset context cannot be reliably routed or validated during response. “Populate the incident with linked event evidence and the identified affected host or identity before assignment” applies to that other condition. The reported evidence is a high-confidence detection appears in Event Monitor, but the incident queue remains empty despite the team expecting a new case; this alternative would address the wrong dependency.
