Critical Infrastructure Protection: Further Efforts Needed to Integrate Planning for and Response to Disruptions on Converged Voice and Data Networks

摘要

Technological advances have led to an increasing convergence of previously separate networks used to transmit voice and data communications. While the benefits of this convergence are enormous, such interconnectivity also poses significant challenges to our nation's ability to respond to major disruptions. Two operations centers--managed by the Department of Homeland Security's (DHS) National Communications System and National Cyber Security Division--plan for and monitor disruptions on voice and data networks. In September 2007, a DHS expert task force made three recommendations toward establishing an integrated operations center that the department agreed to adopt. To determine the status of efforts to establish an integrated center, GAO reviewed documentation, interviewed relevant DHS and private sector officials, and reviewed laws and policies to identify DHS's responsibilities in addressing convergence. DHS has taken the first of three steps toward integrating its centers that are responsible for planning for, monitoring, and responding to disruptions to the communications infrastructure, including voice and data networks, and the security of data and applications that use these networks. Specifically, in November 2007, it moved the operations center for communications infrastructure (NCC Watch) to office space adjacent to the center for data and applications (US-CERT). This close proximity allows the approximately 41 coordination center and 95 readiness team analysts to, among other things, readily collaborate on planned and ongoing activities. In addition, the centers have jointly acquired common software tools to identify and share physical, telecommunications, and cyber information related to performing their missions. The department has not organizationally merged the two centers or invited key private sector critical infrastructure officials to participate in the planning, monitoring, and other activities of the proposed joint operations center. A key factor contributing to DHS's lack of progress in implementing the latter two steps is that completing the integration has not been a top DHS priority. DHS officials stated that they are in the process of drafting a strategic plan to provide overall direction for the activities of the National Communications System and the National Cyber Security Division. However, the plan is in draft and has been so since mid-2007.
