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.
