Question 600
A security automation or reporting check exposes this issue: A threat-hunting workflow should attach a currently observed endpoint process list to an incident, but its EMS connector only retrieves vulnerability inventory. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Match enrichment task action types to the evidence requirement. This long-term control addresses the recurring risk. The technical reason is: Connector actions have distinct outputs; a vulnerability list does not represent running processes. A later acceptance test still needs to confirm: The incident contains the intended endpoint process snapshot and correct asset attribution.
Incorrect Answers
This safeguard, “Document which incident transitions are eligible to trigger response automation”, reduces a different source-defined risk: An incident should launch host enrichment as soon as it is created, but the automation waits for a generic unrelated log event. That risk depends on: INCIDENT_TRIGGER starts from newly created matching incident records rather than arbitrary log messages. The recurring problem here is a threat-hunting workflow should attach a currently observed endpoint process list to an incident, but its EMS connector only retrieves vulnerability inventory. The originally selected control “Match enrichment task action types to the evidence requirement” is more specific because connector actions have distinct outputs; a vulnerability list does not represent running processes.
This safeguard, “Test trigger filtering and alert rate before activating automatic case creation”, reduces a different source-defined risk: A SOC wants to create an incident automatically whenever a new critical IPS event is generated, but a playbook is configured with a manual-only start. That risk depends on: EVENT_TRIGGER runs a playbook for matching created events; ON_DEMAND waits for manual execution. The recurring problem here is a threat-hunting workflow should attach a currently observed endpoint process list to an incident, but its EMS connector only retrieves vulnerability inventory. The originally selected control “Match enrichment task action types to the evidence requirement” is more specific because connector actions have distinct outputs; a vulnerability list does not represent running processes.
This safeguard, “Review playbook schedule timezone and job history during routine maintenance”, reduces a different source-defined risk: A nightly compliance task should aggregate incident indicators at 02:00 even when no new detection occurs. That risk depends on: Scheduled triggers run by configured temporal rules independently of event or incident creation. The recurring problem here is a threat-hunting workflow should attach a currently observed endpoint process list to an incident, but its EMS connector only retrieves vulnerability inventory. The originally selected control “Match enrichment task action types to the evidence requirement” is more specific because connector actions have distinct outputs; a vulnerability list does not represent running processes.
