Question 830
During a security analytics acceptance test, operators report: An SOC investigation covering a night shift uses calendar date filters that unintentionally exclude activity shortly after midnight. What should the analyst or engineer change first to address this condition?
Explanation
Correct Answer
The underlying cause is: An incident interval crossing midnight cannot be faithfully represented by a single daytime date bucket. The correct response is: Use explicit start/end timestamps covering the entire shift and normalize event-time timezone assumptions. Confirm by checking: The final event list includes pre- and post-midnight records from the same investigative interval.
Incorrect Answers
That intervention addresses trusted host administrative source detection, where Identical usernames do not prove both sessions originated from the same approved management path. Here, the relevant failure is instead: An incident interval crossing midnight cannot be faithfully represented by a single daytime date bucket.
That intervention addresses file extraction from log metadata limitation, where Metadata in a security log does not imply the analyzer stores an accessible full copy of the transmitted payload. In this question the necessary remedy is “Use explicit start/end timestamps covering the entire shift and normalize event-time timezone assumptions”, which this alternative does not provide.
That intervention addresses fortiview session latency inferred from duration, where Connection duration alone may include idle time and is not identical to end-user application response latency. The observed condition is an SOC investigation covering a night shift uses calendar date filters that unintentionally exclude activity shortly after midnight; this mechanism addresses another problem.
