Question 720
During a FortiAnalyzer incident investigation, the analysts observe: A widget contains a historical point but a click-through to individual records returns no results after retention cleanup. Which technical explanation most directly accounts for these observations?
Explanation
Correct Answer
The underlying principle is: A summary, cache or earlier export may survive after the underlying log records required for drilldown have expired. Address this by: Verify actual raw or Analytics retention and avoid presenting a stale summary as if all supporting events remain available. The confirming operational observation is: The incident notes which summary data exists and which record-level evidence can no longer be reproduced.
Incorrect Answers
Event severity is one dimension and does not automatically determine operational priority without asset importance or confirmed outcome. “Use asset criticality, exposure, action and event evidence to set triage priority separately from source severity” would remedy that alternative situation, but it would not correct the present issue: a summary, cache or earlier export may survive after the underlying log records required for drilldown have expired.
“Filter the signature and action, then pivot to authenticated user, source IP and device records in the selected interval” is the supported response when an application-level aggregate alone does not identify individual users or show which endpoints were affected. Here the decisive response is “Verify actual raw or Analytics retention and avoid presenting a stale summary as if all supporting events remain available”, so that different intervention does not meet the stated requirement.
Behavioral baselines can flag new legitimate routines and need current business and change context before incident classification. “Correlate the anomaly with the approved job, identity, endpoints and data volume to confirm or challenge its explanation” applies to that other condition. The reported evidence is a widget contains a historical point but a click-through to individual records returns no results after retention cleanup; this alternative would address the wrong dependency.
