Question 190
An incident response engineer inspects the following evidence: FortiAnalyzer flags an endpoint as potentially compromised after IOC matches, and an operator wants to isolate it immediately without validating identity. What result should a responder seek before declaring this issue resolved?
Explanation
Correct Answer
This directly verifies compromised host isolation hypothesis: The proposed response is tied to the correct live asset with documented supporting evidence. The linked remediation is: Confirm endpoint identity, indicator context, current IP and related network activity before any authorized containment. A result from an unrelated SOC function does not prove this requirement.
Incorrect Answers
The case records whether the same authenticated identity initiated the subsequent transfer and whether policy permitted it. This is a different failure mechanism from the current case, which concerns the proposed response is tied to the correct live asset with documented supporting evidence.
This option instead describes the resulting timeline distinguishes a regular heartbeat from an evidenced malicious beacon pattern. Testing that independent mechanism would not show whether the reported fault has been resolved.
The analyst distinguishes unusual employee activity from expected kiosk or scanner transactions. The stem describes fortiAnalyzer flags an endpoint as potentially compromised after IOC matches, and an operator wants to isolate it immediately without validating identity, so this explanation does not account for the observations.
