Cybersecurity Framework Profile for Hybrid Satellite Networks (HSN): Final Annotated Outline



James McCarthy, Joseph Brule, Dan Mamula, Karri Meldorf


The objective of this Cybersecurity Profile is to identify an approach to assess the cybersecurity posture of Hybrid Satellite Networks (HSN) that provide services such as satellite-based systems for communications, position, navigation, and timing (PNT), remote sensing, weather monitoring, and imaging. The HSN systems may interact with other government systems and the Critical Infrastructure as defined by the Department of Homeland Security to mutually increase their resilience. This Profile will consider the cybersecurity of all the interacting systems that form the HSN rather than the traditional approach of a single organization acquiring the entire satellite system that includes the satellite bus, payloads, and ground system. NIST is developing a consistent approach to assess the cybersecurity posture of a space system to facilitate the better understanding of the attack surface, incorporate security, and achieve greater resilience for space systems that may be leveraged by critical infrastructure owners and operators, the Department of Defense, or other government missions.
