Cybersecurity Profile for Hybrid Satellite Networks (HSN) Draft Annotated Outline

The objective of this Cybersecurity Profile is to identify an approach to assess the cybersecurity posture of Hybrid Satellite Networks (HSN) systems that provide services such as:

  • satellite-based systems for communications
  • position, navigation, and timing (PNT)
  • remote sensing
  • weather monitoring
  • imaging

The HSN systems may interact with other government systems and the Critical Infrastructure as defined by the Department of Homeland Security to provide increased resiliency.

This Profile will consider the cybersecurity of all the interacting systems that form the HSN rather than the traditional approach of the government acquiring the entire satellite system that includes the satellite bus, payloads, and ground system.

NIST is developing a consistent approach to better understand the attack surface, incorporate security, and achieve greater resilience for space systems that may be leveraged by critical infrastructure owners and operators, the DoD, or other government missions.

The public comment period for this draft is open through August 9, 2022. See the publication details for a copy of the draft annotated outline and instructions for submitting comments. 

Save the Date: Comments will be addressed during a live adjudication session on August 11, 2022 from 1:00PM-3:00PM EST. Please mark your calendars. Registration information for this session will be shared soon.
