Question 130
Before a monitored change is approved, the SOC finds: A workstation initiates RDP connections to many internal servers, with most attempts denied and a few accepted within minutes. Which supported corrective step best meets the stated requirement?
Explanation
Correct Answer
The underlying cause is: Broad internal management-port scanning can suggest lateral movement, but accepted sessions need distinct identity and server context. The correct response is: Group traffic by source, destination ports, actions and server login events to reconstruct actual successful access. Confirm by checking: The case separates denied probes from accepted RDP sessions supported by host authentication evidence.
Incorrect Answers
That intervention addresses fortiview device filter hides new branch, where A saved device selection or group can exclude a newly added source even when collection and indexing work correctly. Here, the relevant failure is instead: Broad internal management-port scanning can suggest lateral movement, but accepted sessions need distinct identity and server context.
That intervention addresses threat campaign report count reclassification, where A change in grouping, deduplication or severity filters can alter incident counts without altering the raw set of attempts. In this question the necessary remedy is “Group traffic by source, destination ports, actions and server login events to reconstruct actual successful access”, which this alternative does not provide.
That intervention addresses email attachment lure and web pivot, where Email detection and subsequent web access must be correlated across distinct products using consistent user and time context. The observed condition is a workstation initiates RDP connections to many internal servers, with most attempts denied and a few accepted within minutes; this mechanism addresses another problem.
