Question 430
An incident response engineer inspects the following evidence: An analyst launches automated containment, but the connector reports failure and the incident remains assigned to a low-priority queue. What monitoring or governance control is most relevant to this weakness?
Explanation
Correct Answer
This safeguard directly addresses case escalation after failed remediation: Design escalation rules for unresolved high-severity incidents and automation errors. The risk being prevented is: A failed mitigation increases unresolved risk and should not be treated as a completed incident response step. A safeguard aimed at another fault would not control this issue.
Incorrect Answers
Known scanner behavior explains selected detections but does not justify removing detection coverage network-wide. “Maintain expiring scanner exceptions tied to documented test windows and asset identity” would remedy that alternative situation, but it would not correct the present issue: a failed mitigation increases unresolved risk and should not be treated as a completed incident response step.
“Test handler data selection against current source-to-ADOM inventory before enablement” is the supported response when the event engine evaluates its selected ADOM and log sources; cross-domain data does not appear by assumption. Here the decisive response is “Design escalation rules for unresolved high-severity incidents and automation errors”, so that different intervention does not meet the stated requirement.
MITRE taxonomy metadata classifies a rule but does not itself define log matching conditions or event thresholds. “Review both detection logic and ATT&CK labels during rule quality audits” applies to that other condition. The reported evidence is an analyst launches automated containment, but the connector reports failure and the incident remains assigned to a low-priority queue; this alternative would address the wrong dependency.
