Question 860
At the Maplehaven online learning platform, Splunk indexes firewall events but no detection analytic alerts on repeated suspicious authentication failures. How should the organization sustain the improvement?
Explanation
Correct Answer
For the Maplehaven online learning platform, this maintenance action preserves the fix: tune detection thresholds and investigate false positives. It should be revisited as the workload evolves.
Incorrect Answers
The suggested preventive check is: Alert on ingestion gaps and integration failures. Its technical scope concerns: Central correlation is incomplete when a required telemetry source stops reporting. This question asks how to sustain control over: Raw log availability does not automatically create actionable SIEM findings. The more targeted safeguard is: Tune detection thresholds and investigate false positives.
That routine supports mab for non 802.1x devices, but the relevant ongoing risk requires the team to tune detection thresholds and investigate false positives. For the Maplehaven online learning platform, the direct corrective action is to build a relevant Splunk Enterprise Security correlation search or detection rule with risk-based triage.
Verify CoA authorization after AAA credential changes. That safeguard would help prevent recurrence of: Authentication configuration and dynamic authorization messages need compatible trust material. The risk being reviewed here is instead: Raw log availability does not automatically create actionable SIEM findings. The matching ongoing control is: Tune detection thresholds and investigate false positives.
