The firewall implementation must produce audit log records that contain sufficient information to establish what type of event 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. Associating event types with detected events in the application and audit logs provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured firewall. Without this capability, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. To support the auditing requirement, the firewall account and audit management functions must be configured to transmit the required audit events to the site's central audit server (e.g., SYSLOG server), as required by CCI-000136.

Check Text ( C-SRG-NET-000074-FW-000051_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 determine the type or category for each audit event recorded in the audit log. If the audit log event records do not include enough information to determine what type of event occurred, this is a finding.
