Question 980
During a cross-team security policy review at Atlas Scientific, engineers say that they resolved this finding: An event references a quarantined object but investigators cannot tell its source or execution chain. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
The incident record identifies file origin, process lineage, and action outcome. This is the decisive evidence for the original problem: An event references a quarantined object but investigators cannot tell its source or execution chain. It verifies that the intended corrective control—Examine endpoint process and file trajectory metadata in the Secure Endpoint event—works in the relevant environment; a completed change ticket alone would not prove the outcome at Atlas Scientific.
Incorrect Answers
Historical sightings are correlated and the affected endpoints are contained or cleared. This would be relevant evidence for a different failure: An endpoint shows file detection after a verdict changed from unknown to malicious days later, usually addressed by Use retrospective detection events and file trajectory to locate prior exposure and respond. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: The incident record identifies file origin, process lineage, and action outcome.
Investigation separates exposed-only devices from a confirmed active compromise. This would be relevant evidence for a different failure: Several detections share the same hash but only one device shows outbound command activity, usually addressed by Correlate file events with network and process telemetry instead of assuming equal host severity. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: The incident record identifies file origin, process lineage, and action outcome.
The case distinguishes blocked attempts from executed compromise and identifies the appropriate affected assets. This would be relevant evidence for a different failure: A detection event is labeled malicious but analysts assume its severity alone means every host is infected, usually addressed by Interpret event disposition, timestamp, file activity, and actual affected host before escalation. It does not demonstrate that the current problem at Atlas Scientific was resolved. The specific required evidence is: The incident record identifies file origin, process lineage, and action outcome.
