Review of Perimeter Firewalls

Our objective was to determine whether the network perimeter firewalls are properly configured and functioning to safeguard information technology (IT) according to Postal Service standards and industry best practices. Perimeter firewalls are the first line of defense of an organization’s IT network. They are essential components for detecting and protecting the network by blocking unnecessary incoming traffic to publicly available systems.
