Question 160
A security automation or reporting check exposes this issue: An analyst sees an outbreak-alert statistic increase and mistakenly searches only traffic logs for messages tagged as incidents. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Document the difference between outbreak events and formal incident records. This long-term control addresses the recurring risk. The technical reason is: Outbreak alerts are surfaced through matching event records and do not necessarily equal manually created incident tickets. A later acceptance test still needs to confirm: The outbreak event list reproduces the dashboard count and provides event detail for triage.
Incorrect Answers
This safeguard, “Use documented dashboard time windows for daily incident reporting”, reduces a different source-defined risk: An analyst expects a newly created incident to appear on a SOC Dashboard widget, but its time filter excludes the incident's creation time. That risk depends on: Dashboard widgets summarize records matching their selected time range; valid incidents outside it may be omitted. The recurring problem here is an analyst sees an outbreak-alert statistic increase and mistakenly searches only traffic logs for messages tagged as incidents. The originally selected control “Document the difference between outbreak events and formal incident records” is more specific because outbreak alerts are surfaced through matching event records and do not necessarily equal manually created incident tickets.
This safeguard, “Use incident-focused dashboard views in threat response playbooks”, reduces a different source-defined risk: A network analyst focuses on device CPU graphs during a suspected targeted intrusion and ignores the SOC's severity-sorted incident panel. That risk depends on: Operational resource metrics and security incident priority answer different questions; one cannot substitute for the other. The recurring problem here is an analyst sees an outbreak-alert statistic increase and mistakenly searches only traffic logs for messages tagged as incidents. The originally selected control “Document the difference between outbreak events and formal incident records” is more specific because outbreak alerts are surfaced through matching event records and do not necessarily equal manually created incident tickets.
This safeguard, “Monitor licensing, UTM log coverage, and threat-data freshness together”, reduces a different source-defined risk: The FortiView Indicator of Compromise widget is empty after onboarding a FortiGate that has no UTM logging and no threat intelligence subscription. That risk depends on: IoC summaries depend on supporting security telemetry and threat intelligence, not only FortiGate reachability. The recurring problem here is an analyst sees an outbreak-alert statistic increase and mistakenly searches only traffic logs for messages tagged as incidents. The originally selected control “Document the difference between outbreak events and formal incident records” is more specific because outbreak alerts are surfaced through matching event records and do not necessarily equal manually created incident tickets.
