Question 640
A multi-device security analysis reveals this requirement: An incident playbook enriches the right indicator but attaches its result to an unrelated older case because the incident ID was hardcoded. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Review dynamic incident identifiers before copying automation templates. This long-term control addresses the recurring risk. The technical reason is: A constant case identifier breaks per-run context propagation even if enrichment itself succeeds. A later acceptance test still needs to confirm: Each test run attaches its data to the incident that launched that run.
Incorrect Answers
This safeguard, “Recheck automation timezones after daylight-saving or site scheduling changes”, reduces a different source-defined risk: A scheduled playbook appears to skip a run after a timezone change even though the local administrator's clock displays 02:00. That risk depends on: A schedule's effective next-run instant may differ from the analyst's displayed local time. The recurring problem here is an incident playbook enriches the right indicator but attaches its result to an unrelated older case because the incident ID was hardcoded. The originally selected control “Review dynamic incident identifiers before copying automation templates” is more specific because a constant case identifier breaks per-run context propagation even if enrichment itself succeeds.
This safeguard, “Require explicit trigger scope and rate-impact review for automated actions”, reduces a different source-defined risk: An event-driven playbook starts on almost every low-risk alert, overwhelming analysts, because no starter filters were configured. That risk depends on: An EVENT_TRIGGER without filters can apply to all new events, so broad starters create unwanted executions. The recurring problem here is an incident playbook enriches the right indicator but attaches its result to an unrelated older case because the incident ID was hardcoded. The originally selected control “Review dynamic incident identifiers before copying automation templates” is more specific because a constant case identifier breaks per-run context propagation even if enrichment itself succeeds.
This safeguard, “Use guarded test-mode enforcement and explicit connector prerequisites”, reduces a different source-defined risk: An automated block fails even though the indicator is enriched; the case lacks a supported blocking connector or approved target scope. That risk depends on: Enrichment provides information, while blocking requires a separate operational action path and permission. The recurring problem here is an incident playbook enriches the right indicator but attaches its result to an unrelated older case because the incident ID was hardcoded. The originally selected control “Review dynamic incident identifiers before copying automation templates” is more specific because a constant case identifier breaks per-run context propagation even if enrichment itself succeeds.
