Question 1160
During a scheduled security controls review at Aster Mutual, engineers say that they resolved this finding: Security events are visible in Splunk but the response process has no case ownership or action tracking. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
A high-priority alert produces an owned case and records the authorized containment sequence. This is the decisive evidence for the original problem: Security events are visible in Splunk but the response process has no case ownership or action tracking. It verifies that the intended corrective control—Integrate alerts with defined incident management and SOAR actions including audit and escalation—works in the relevant environment; a completed change ticket alone would not prove the outcome at Aster Mutual.
Incorrect Answers
A controlled unusual peer-to-peer pattern triggers a contextual security finding. This would be relevant evidence for a different failure: Network flow analysis misses low-and-slow lateral movement because all decisions rely on static signatures, usually addressed by Use behavioral baselines or appropriately validated AI/ML analytics alongside deterministic detection. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: A high-priority alert produces an owned case and records the authorized containment sequence.
The analytic connects the suspect user session to its downstream protected resource access. This would be relevant evidence for a different failure: A Splunk search detects suspicious sign-ins but cannot associate them with firewall flows to sensitive servers, usually addressed by Normalize entity identity and correlate authentication data with network traffic observations. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: A high-priority alert produces an owned case and records the authorized containment sequence.
The case links related alerts to a single affected endpoint with a coherent event timeline. This would be relevant evidence for a different failure: Two SOC tools raise unrelated incidents for the same host because network and endpoint events lack common identity, usually addressed by Correlate endpoint, identity, and network telemetry through XDR or SIEM entity mapping. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: A high-priority alert produces an owned case and records the authorized containment sequence.
