Question 620
During a review of an enterprise SOC workflow, the administrator finds: A FortiAnalyzer EVENT_TRIGGER playbook never starts even though a related event exists, and its filter requires the wrong severity value. Which ongoing safeguard best addresses the original risk?
Explanation
Correct Answer
Keep representative filter match and nonmatch tests with trigger changes. This long-term control addresses the recurring risk. The technical reason is: A playbook event starter evaluates configured matching conditions and ignores nonmatching events. A later acceptance test still needs to confirm: A qualifying synthetic event starts the workflow and a low-severity negative test does not.
Incorrect Answers
This safeguard, “Reconcile connector endpoints after firewall replacements and HA changes”, reduces a different source-defined risk: A playbook job fails after the target FortiGate is replaced, because its connector still points to a retired serial number or address. That risk depends on: Automation connectors bind tasks to concrete external resources that may change after infrastructure replacements. The recurring problem here is a FortiAnalyzer EVENT_TRIGGER playbook never starts even though a related event exists, and its filter requires the wrong severity value. The originally selected control “Keep representative filter match and nonmatch tests with trigger changes” is more specific because a playbook event starter evaluates configured matching conditions and ignores nonmatching events.
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 a FortiAnalyzer EVENT_TRIGGER playbook never starts even though a related event exists, and its filter requires the wrong severity value. The originally selected control “Keep representative filter match and nonmatch tests with trigger changes” is more specific because a playbook event starter evaluates configured matching conditions and ignores nonmatching events.
This safeguard, “Maintain separate read-only analyst and automation-maintainer roles”, reduces a different source-defined risk: An administrator cannot edit an automation playbook despite having access to read incidents and view its workflow graph. That risk depends on: Playbook management requires write authorization distinct from permission to view incident lists. The recurring problem here is a FortiAnalyzer EVENT_TRIGGER playbook never starts even though a related event exists, and its filter requires the wrong severity value. The originally selected control “Keep representative filter match and nonmatch tests with trigger changes” is more specific because a playbook event starter evaluates configured matching conditions and ignores nonmatching events.
