Question 970
At Newbridge Charity, a team reports that it corrected the following problem affecting donation applications and volunteer accounts: A detection event is labeled malicious but analysts assume its severity alone means every host is infected. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
The case distinguishes blocked attempts from executed compromise and identifies the appropriate affected assets. This is the decisive evidence for the original problem: A detection event is labeled malicious but analysts assume its severity alone means every host is infected. It verifies that the intended corrective control—Interpret event disposition, timestamp, file activity, and actual affected host before escalation—works in the relevant environment; a completed change ticket alone would not prove the outcome at Newbridge Charity.
Incorrect Answers
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 Newbridge Charity was resolved. The specific required evidence is: The case distinguishes blocked attempts from executed compromise and identifies the appropriate affected assets.
An analyst can verify whether the file was blocked, quarantined, or allowed and responds appropriately. This would be relevant evidence for a different failure: A console records a malicious file event but the assigned action is 'monitor' and no quarantine occurred, usually addressed by Interpret the effective policy and reported disposition before declaring the threat contained. It does not demonstrate that the current problem at Newbridge Charity was resolved. The specific required evidence is: The case distinguishes blocked attempts from executed compromise and identifies the appropriate affected assets.
The investigation shows one related campaign without double-counting separate file names. This would be relevant evidence for a different failure: A file detection repeats under different filenames while its digest is unchanged, usually addressed by Group events by verified file hash and correlate devices and event timing. It does not demonstrate that the current problem at Newbridge Charity was resolved. The specific required evidence is: The case distinguishes blocked attempts from executed compromise and identifies the appropriate affected assets.
