Right on Time: Protecting Critical Infrastructure Against Threats

Critical public infrastructure systems that rely on GNSS for reception of positioning, navigation and timing (PNT) data have been identified by national security agencies across the globe as potential cybersecurity attack vectors. Late in 2020, the U.S. Department of Homeland Security (DHS) published the “Resilient PNT Conformance Framework” guidelines, providing a common reference point to help critical infrastructures become more resilient to PNT attack threats. Within the framework, a cybersecurity approach has been proposed.

Prevent. In this first layer of defence, threats are prevented from entering a system. However, it must be assumed that it is not possible to stop all threats.

Respond. Atypical errors or anomalies are detected and action taken, such as mitigation, containment and reporting. The system should ensure an adequate response to externally induced, atypical errors before recovery is needed.

Recover. The last line of defence is returning to a proper working state and defined performance.
