Question 550
During a FortiAnalyzer incident investigation, the analysts observe: A detection engineer assigns a MITRE technique label to an event handler and expects matching attack events without creating log rules. Which action directly fixes the identified FortiAnalyzer workflow issue?
Explanation
Correct Answer
The underlying cause is: MITRE taxonomy metadata classifies a rule but does not itself define log matching conditions or event thresholds. The correct response is: Configure actual event rules and test supporting data before using technique mapping for reporting. Confirm by checking: A qualifying log generates an event that carries the intended classification metadata.
Incorrect Answers
That intervention addresses case escalation after failed remediation, where A failed mitigation increases unresolved risk and should not be treated as a completed incident response step. Here, the relevant failure is instead: MITRE taxonomy metadata classifies a rule but does not itself define log matching conditions or event thresholds.
That intervention addresses event handler false positive with scanning appliance, where Known scanner behavior explains selected detections but does not justify removing detection coverage network-wide. In this question the necessary remedy is “Configure actual event rules and test supporting data before using technique mapping for reporting”, which this alternative does not provide.
That intervention addresses event-handler data selector adom mismatch, where The event engine evaluates its selected ADOM and log sources; cross-domain data does not appear by assumption. The observed condition is a detection engineer assigns a MITRE technique label to an event handler and expects matching attack events without creating log rules; this mechanism addresses another problem.
