Blog Editor’s Note: Interesting article building upon the idea of a national resilient timing architecture.
We have published two white papers on this idea – “A Resilient National Timing Architecture” in 2020, and “A Resilient National Architecture, Now for an RFP!” in 2021. In them we acknowledge the idea that such an architecture will need some monitoring, measurement, and management.
This paper expands upon that a bit.

Managing live sky and terrestrial time sources to protect critical infrastructure against cybersecurity threats
By Greg Wolff, Microchip Technology
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.
