Description
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.
ℹ️ Check
Interview the SA to verify that a report exists to notify the SA and ISSO, at a minimum, when an attack is detected on multiple devices and hosts within its scope of coverage. Interview the ISSO to confirm receipt of this report. If a report does not exist, or the ISSO does not confirm receipt of this report, this is a finding.
✔️ Fix
Configure Splunk Enterprise, using the Reporting and Alert tools, to notify the SA and ISSO, at a minimum, when an attack is detected on multiple devices and hosts within its scope of coverage.
