DHS Publishes Two Free Resources to Protect Critical Infrastructure from GPS Vulnerabilities

The GPS Whitelist Development Guide presents a software assurance approach to addressing potential vulnerabilities and increasing reliability of GPS receivers.

The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) announced today it has published a Global Positioning System (GPS) Receiver Whitelist Development Guide and a new release of the Positioning, Navigation, and Timing (PNT) Integrity Library to protect against the spoofing, or deceiving, of GPS devices through false signals. These resources advance the design of PNT systems and increase resilience of critical infrastructure to PNT disruptions.
