• Abstract:
  To assess the risks and potential effects from disruptions in the Global ; Positioning System (GPS) on critical infrastructure, the Department of Homeland ; Security (DHS) published the GPS National Risk Estimate (NRE) in 2012. In ; doing so, DHS conducted a scenario-based risk assessment for four critical ; infrastructure sectors using subject matter experts from inside and outside of ; government. Risk assessments involve complex analysis, and conducting a risk ; assessment across multiple sectors with many unknowns and little data is ; challenging. DHS’s risk management guidance can be used to help address such ; challenges. However, we found the NRE lacks key characteristics of risk ; assessments outlined in DHS’s risk management guidance and, as a result, is ; incomplete and has limited usefulness to inform mitigation planning, priorities, ; and resource allocation. A plan to collect and assess additional data and ; subsequent efforts to ensure that the risk assessment is consistent with DHS ; guidance would contribute to more effective GPS risk management.
