The firewall implementation must produce audit log records containing sufficient information to establish the source of the event.

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 the actions of specific events provides a means to investigate an attack, recognize resource utilization or capacity thresholds, or to simply identify an improperly configured firewall. If the originator of the log record is not recorded, it will be difficult to establish and correlate the series of events leading up to an outage or attack.

Check Text ( C-SRG-NET-000077-FW-000054_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 sufficient information to ascertain the source of the events (e.g., IP address, session or packet ID). If the audit log event records do not include sufficient information to ascertain the source of the events, this is a finding.
