Getting government agencies to share security information means first identifying the networks involved. A congressional briefing by the Government Accountability Office identified nine agencies and 34 networks that support homeland security functions (two of these networks are still under development). The briefing outlines each network and gives examples of how they might work together for counterterrorism efforts.

A January report from the Government Accountability Office reveals that 911 emergency calls may not be cyber safe. The document addresses five agencies that coordinate with state and local governments on cybersecurity-related activities, including the Department of Homeland Security, and cites the increased information-sharing between these agencies as a security concern. “Because these critical systems are becoming more interconnected, they are also increasingly susceptible to cyber-based threats that accompany the use of Internet-based services,” states the report. “This, in turn, could impact the availability of 911 services.”
