While the Nuclear Regulatory Commission (NRC) has bolstered security at nuclear plants since 9-11, the GAO cannot yet say whether each plant "has taken reasonable and appropriate steps to address the new design-basis threat," which establishes the maximum terrorist threat that a facility must defend against. Security plans reviewed by GAO lacked "important site-specific information," including where responding guards were to be stationed. Moreover, the GAO noted that the NRC isn't sharing with plants lessons learned from inspections at those plants.
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.”
