Question 70
During a security analytics acceptance test, operators report: A policy owner asks which users were affected by one newly blocked application signature during a scheduled change. What should the analyst or engineer change first to address this condition?
Explanation
Correct Answer
The underlying cause is: An application-level aggregate alone does not identify individual users or show which endpoints were affected. The correct response is: Filter the signature and action, then pivot to authenticated user, source IP and device records in the selected interval. Confirm by checking: The affected users are identified with matching application-control event IDs and times.
Incorrect Answers
That intervention addresses multiple event-handler alerts for one incident, where Distinct event handlers may match different features of one underlying host incident, so count of alerts is not count of compromises. Here, the relevant failure is instead: An application-level aggregate alone does not identify individual users or show which endpoints were affected.
That intervention addresses user entity analytics baseline change, where Behavioral baselines can flag new legitimate routines and need current business and change context before incident classification. In this question the necessary remedy is “Filter the signature and action, then pivot to authenticated user, source IP and device records in the selected interval”, which this alternative does not provide.
That intervention addresses fortiview failed transaction due missing raw logs, where A summary, cache or earlier export may survive after the underlying log records required for drilldown have expired. The observed condition is a policy owner asks which users were affected by one newly blocked application signature during a scheduled change; this mechanism addresses another problem.
