Question 460
Before a monitored change is approved, the SOC finds: An analyst transfers a malware case to the endpoint team without preserving the investigations and tools already run. Which assurance step most directly controls this future failure mode?
Explanation
Correct Answer
This safeguard directly addresses incident reassignment with missing handoff: Use a standardized case handoff format and maintain incident audit history. The risk being prevented is: A reassigned incident can lose context when notes, evidence and executed actions are not retained within its audit history. A safeguard aimed at another fault would not control this issue.
Incorrect Answers
Absence of new alerts is not equivalent to verified recovery when logging or malicious activity may have stopped temporarily. “Enforce a closure checklist that distinguishes quiet telemetry from confirmed resolution” would remedy that alternative situation, but it would not correct the present issue: a reassigned incident can lose context when notes, evidence and executed actions are not retained within its audit history.
“Require asset identification and supporting event links in incident intake templates” is the supported response when a case without evidence-backed affected-asset context cannot be reliably routed or validated during response. Here the decisive response is “Use a standardized case handoff format and maintain incident audit history”, so that different intervention does not meet the stated requirement.
Overlapping detections may describe one underlying host investigation rather than independent incidents. “Design event-correlation and case-deduplication practices around asset, time and indicator context” applies to that other condition. The reported evidence is an analyst transfers a malware case to the endpoint team without preserving the investigations and tools already run; this alternative would address the wrong dependency.
