Critical Infrastructure Protection: Sector-Specific Agencies Need to Better Measure Cybersecurity Progress
GAO-16-79: Published: Nov 19, 2015. Publicly Released: Nov 19, 2015.
Sector-specific agencies (SSA) determined the significance of cyber risk to networks and industrial control systems for all 15 of the sectors in the scope of GAO's review. Specifically, they determined that cyber risk was significant for 11 of 15 sectors. Although the SSAs for the remaining four sectors had not determined cyber risks to be significant during their 2010 sector-specific planning pro...
Defense Infrastructure: Improvements in DOD Reporting and Cybersecurity Implementation Needed to Enhance Utility Resilience Planning
GAO-15-749: Published: Jul 23, 2015. Publicly Released: Jul 23, 2015.
Department of Defense (DOD) installations have experienced utility disruptions resulting in operational and fiscal impacts due to hazards such as mechanical failure and extreme weather. Threats, such as cyber attacks, also have the potential to cause disruptions. In its June 2014 Annual Energy Management Report (Energy Report) to Congress, DOD reported 180 utility disruptions lasting 8 hours or lo...
Federal Facility Cybersecurity: DHS and GSA Should Address Cyber Risk to Building and Access Control Systems
GAO-15-6: Published: Dec 12, 2014. Publicly Released: Jan 12, 2015.
The Department of Homeland Security (DHS) has taken preliminary steps to begin to understand the cyber risk to building and access controls systems in federal facilities. For example, in 2013, components of DHS's National Protection and Programs Directorate (NPPD) conducted a joint assessment of the physical security and cybersecurity of a federal facility. However, significant work remains.Lack o...
