Question 890
An incident response engineer inspects the following evidence: A custom threat event fires correctly but is absent from the team's saved Event Monitor threat view. What is the most appropriate response to the reported operational problem?
Explanation
Correct Answer
The underlying cause is: Views depend on event classification and saved filtering; event existence alone does not guarantee inclusion in every dashboard. The correct response is: Check handler tags and the view filter and align them to the documented intended category. Confirm by checking: The test event appears in the targeted threat view with its linked log intact.
Incorrect Answers
That intervention addresses event monitor tag view misclassification, where Event handlers apply classification tags used to group events into Event Monitor views; a rule can fire with incorrect tags. Here, the relevant failure is instead: Views depend on event classification and saved filtering; event existence alone does not guarantee inclusion in every dashboard.
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 “Check handler tags and the view filter and align them to the documented intended category”, which this alternative does not provide.
That intervention addresses mitre technique metadata does not trigger detection, where MITRE taxonomy metadata classifies a rule but does not itself define log matching conditions or event thresholds. The observed condition is a custom threat event fires correctly but is absent from the team's saved Event Monitor threat view; this mechanism addresses another problem.
