Question 180
During a FortiAnalyzer 7.6 analytics review, the team discovers: An SOC rule must detect a failed login burst followed by one successful login rather than simply any two authentication events. Which assurance step most directly controls this future failure mode?
Explanation
Correct Answer
This safeguard directly addresses correlation handler ordered security stages: Document sequence, grouping and expiration conditions when maintaining multi-stage detections. The risk being prevented is: A simple event count does not establish the order or relationship of multiple steps required for an attack pattern. A safeguard aimed at another fault would not control this issue.
Incorrect Answers
An excessive correlation window can connect unrelated events that happen to share a hostname or indicator. “Review correlation windows against both false-positive history and expected attack timing” would remedy that alternative situation, but it would not correct the present issue: a simple event count does not establish the order or relationship of multiple steps required for an attack pattern.
“Include tag and dashboard routing in event handler acceptance tests” is the supported response when event handlers apply classification tags used to group events into Event Monitor views; a rule can fire with incorrect tags. Here the decisive response is “Document sequence, grouping and expiration conditions when maintaining multi-stage detections”, so that different intervention does not meet the stated requirement.
Event generation does not itself prove a notification action is configured and connected to the correct handler. “Test notification profile recipients and transport after on-call roster and mail-server changes” applies to that other condition. The reported evidence is an SOC rule must detect a failed login burst followed by one successful login rather than simply any two authentication events; this alternative would address the wrong dependency.
