Description
In order to determine what is happening within the network infrastructure or to resolve and trace an attack, the firewall implementation must support the organization's capability to correlate the audit log data from multiple firewalls to acquire a clear understanding of events. In order to correlate auditable events, timestamps are needed on all of the log records.
