The firewall implementation must produce audit log records containing sufficient information to determine if the event was a success or failure.

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. Denied traffic must be logged. 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.

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 success or failure of the action or request (e.g., login, permission changes) of each event. If the audit log event records do not include sufficient information to ascertain success or failure of the action/request of the event, this is a finding.
