摘 要：GAO has identified the protection of systems supporting the nation's critical infrastructure--which includes the communications sector--as a government-wide high-risk area. GAO was asked to (1) identify the roles of and actions taken by key federal entities to help protect communications networks from cyber-based threats, (2) assess what is known about the extent to which cyber incidents affecting the communications networks have been reported to the FCC and DHS, and (3) determine if Defense's pilot programs to promote cybersecurity in the defense industrial base can be used in the communications sector. To do this, GAO focused on core and access networks that support communication services, as well as critical components supporting the Internet. GAO analyzed federal agency policies, plans, and other documents; interviewed officials; and reviewed relevant reports.
