Question 60
During a security analytics acceptance test, operators report: A security analyst attaches an external threat-intelligence indicator to a case without recording why it matches the observed host. What evidence would best demonstrate that the intended workflow now works?
Explanation
Correct Answer
This directly verifies ioc indicator attribution to case: A second responder can trace the IOC to a specific original event instead of relying on a bare copied string. The linked remediation is: Link the relevant observed log field, time and source to the indicator record and case narrative. A result from an unrelated SOC function does not prove this requirement.
Incorrect Answers
The incident explicitly records the feed version, freshness and supporting present-day evidence. This is a different failure mechanism from the current case, which concerns a second responder can trace the IOC to a specific original event instead of relying on a bare copied string.
This option instead describes a deliberate test blocks only the expected benign target and the reversal procedure restores baseline state. Testing that independent mechanism would not show whether the reported fault has been resolved.
The incident contains useful error evidence without revealing the credential, and the old token no longer works. The stem describes a security analyst attaches an external threat-intelligence indicator to a case without recording why it matches the observed host, so this explanation does not account for the observations.
