NIST issued NISTIR 8323 since “It seeks to protect the national and economic security of the United States from the disruption or manipulation of systems that form or use PNT data and information vital to the functioning of U.S. critical infrastructure and technology-based industries.” The February 2021 report entitled “Foundational PNT Profile: Applying the Cybersecurity Framework for the Responsible Use of Positioning, Navigation, and Timing (PNT) Services” was issued based on Executive Order 13905, Strengthening National Resilience Through Responsible Use of Positioning, Navigation, and Timing (PNT) Services, was issued on February 12, 2020 to address the four components of responsible use of PNT:
1. Identify systems that use or form PNT data.
2. Identify PNT data sources.
3. Detect disruption and manipulation of the systems that form or use PNT services and data.
4. Manage risk regarding responsible use of these systems.
Since everybody uses PNT Services please take a look at this NIST report.
