Question 500
During a FortiAnalyzer incident investigation, the analysts observe: A workstation initiates RDP connections to many internal servers, with most attempts denied and a few accepted within minutes. Which observed result most convincingly verifies the correction?
Explanation
Correct Answer
This directly verifies suspicious internal lateral rdp attempts: The case separates denied probes from accepted RDP sessions supported by host authentication evidence. The linked remediation is: Group traffic by source, destination ports, actions and server login events to reconstruct actual successful access. A result from an unrelated SOC function does not prove this requirement.
Incorrect Answers
A second analyst can rerun the query and reproduce the sampled events over the same retained interval. This is a different failure mechanism from the current case, which concerns the case separates denied probes from accepted RDP sessions supported by host authentication evidence.
This option instead describes a controlled log from the new branch appears in the expected summary after filter correction. Testing that independent mechanism would not show whether the reported fault has been resolved.
The report identifies the specific aggregation or filtering change responsible for the difference. The stem describes a workstation initiates RDP connections to many internal servers, with most attempts denied and a few accepted within minutes, so this explanation does not account for the observations.
