| Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being performed on the system, where an event occurred, when an event occurred, and by whom the event was triggered, 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.
The audited events must be time correlated to within the organizationally defined level of tolerance, in order to conduct accurate forensic analysis of the events.
Audit aggregation should be performed on the firewall application audit log on the organization's central log server, thus this is not a function performed by the firewall itself. |
