Discussion

Detecting when multiple systems are showing anomalies can often indicate an attack. Notifying appropriate personnel can initiate a proper response and mitigation of the attack. Splunk can aggregate events from multiple devices and create alerts when specific events occur. Detecting similar events on multiple devices simultaneously may indicate an attack. The ability to alert and report on this activity can aid in thwarting an attack.

Interview the ISSO to confirm receipt of this notification.

If a report does not exist, or the ISSO does not confirm receipt of this report, this is a finding.
