Question 440
An incident response engineer inspects the following evidence: The SOC interprets FortiView's high total traffic count as the number of detected attacks and overstates risk to executives. What monitoring or governance control is most relevant to this weakness?
Explanation
Correct Answer
This safeguard directly addresses threat widget versus volume chart: Label charts with the underlying log category and aggregation method before distributing risk summaries. The risk being prevented is: Traffic session totals and security threat detections count different records, each requiring its own log subtype and metric. A safeguard aimed at another fault would not control this issue.
Incorrect Answers
High bandwidth volume alone does not prove malicious behavior and measures a different dimension from detections and security actions. “Correlate traffic utilization metrics with security detections before assigning incident severity” would remedy that alternative situation, but it would not correct the present issue: traffic session totals and security threat detections count different records, each requiring its own log subtype and metric.
“Monitor identity-field coverage and treat large sudden unknown-user increases as a telemetry quality signal” is the supported response when session logs cannot show authenticated user identity unless the relevant identity source and log fields are available and associated. Here the decisive response is “Label charts with the underlying log category and aggregation method before distributing risk summaries”, so that different intervention does not meet the stated requirement.
Destination IP totals do not reliably identify a detected application, especially when multiple services share hosting addresses. “Correlate application identity with traffic and destination fields rather than inferring apps from IPs alone” applies to that other condition. The reported evidence is the SOC interprets FortiView's high total traffic count as the number of detected attacks and overstates risk to executives; this alternative would address the wrong dependency.
