Question 640
When validating a security detection workflow, the team notes: An analyst observes an application session lasting through midnight but believes it was created twice because daily charts display activity on both dates. Which action directly fixes the identified FortiAnalyzer workflow issue?
Explanation
Correct Answer
The underlying cause is: Long-lived flows can contribute usage across report windows, and time aggregation does not necessarily correspond to new session creation. The correct response is: Inspect raw session start, end and duration fields and the widget's aggregation method. Confirm by checking: The single long-lived session is distinguished from genuinely separate connections when reconciling daily totals.
Incorrect Answers
That intervention addresses application-control category blocked, where An application-control policy may identify and block traffic based on application signatures independently of ordinary port permissions. Here, the relevant failure is instead: Long-lived flows can contribute usage across report windows, and time aggregation does not necessarily correspond to new session creation.
That intervention addresses ips signature versus exploitation evidence, where An IPS signature detection shows matched suspicious traffic but does not alone prove payload execution or compromise on the target. In this question the necessary remedy is “Inspect raw session start, end and duration fields and the widget's aggregation method”, which this alternative does not provide.
That intervention addresses traffic bytes versus session count, where Many short low-volume sessions can outnumber fewer high-volume sessions, so count and byte volume are distinct metrics. The observed condition is an analyst observes an application session lasting through midnight but believes it was created twice because daily charts display activity on both dates; this mechanism addresses another problem.
