The firewall implementation must produce audit log records containing sufficient information to establish where the events occurred.

Description
It is essential for security personnel to know what is being done, what was attempted, where it was done, when it was done, and by whom it was done in order to compile an accurate risk assessment. Logging network location information for each detected event provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured firewall. In order to establish and correlate the series of events leading up to an outage or attack, it is imperative the location of the event is recorded in all log records.

Check Text ( C-45465r1_chk )
Examine the audit log configuration on the firewall or view several alert records on the organization's central audit log server. Verify the entries sent to the audit log include the location of each event (e.g., network name, network subnet, network segment, or organization). If the audit log events do not include the event location, this is a finding.

Fix Text (F-42038r1_fix)
Configure the firewall implementation to ensure entries sent to the audit log include the location of each event (e.g., network name, network subnet, network segment, or organization).
