Hybrid Satellite Networks (HSN) Cybersecurity

The space sector is transitioning away from traditional vertically integrated entities and towards an aggregation of independently owned and operated segments that create a space system. The HSN Architecture provides opportunity to be secure, scalable, responsive, resilient, and globally information centric. HSN are flexible which enables space to remain technologically relevant and trusted during times of rapid technological change as well as being adaptable to an increasing threat and contested space and terrestrial environment. 

Cybersecurity Framework (CSF) Profile for Hybrid Satellite Networks

Hybrid Satellite Networks (HSN) present opportunities for organizations to leverage existing space-based capabilities and platforms through means such as hosted payloads, ground infrastructure as a service, virtualized satellite operation centers, etc. There is a need to ensure that these systems are secure, and that the integration of components is done in a manner acceptable to the participating organizations. In collaboration with subject matter experts to include satellite builders, consultants, acquisition authorities, operators (commercial and government), academia, and other interested parties, NIST has developed the HSN Cybersecurity Framework (CSF) Profile to provide guidance for space stakeholders.

A Hybrid Satellite Network (HSN) utilizes multiple components in a terrestrial and space communications infrastructure to provide extended global communications and services across a diverse scope of connecting points. The HSN architecture may be a collection of independently owned satellites and/or payloads that communicate across disparate government and/or commercial networks. HSN system services may include satellite-based communications, position, navigation, and timing (PNT), remote sensing, weather monitoring, and imaging. These systems may interact with government systems and critical infrastructure (as defined by the Department of Homeland Security) as well as to provide a means of assessment. These systems may have varying levels of trust among different components, requiring frameworks for establishing confidentiality and integrity of individual components while still enabling availability of required shared services.

The HSN Architecture provides opportunity to be secure, scalable, responsive, resilient, and globally information centric.  HSN are flexible which enables space to remain technologically relevant and trusted during times of rapid technological change as well as being adaptable to an increasing threat and contested space and terrestrial environment. 

Working with industry stakeholders, the NCCoE developed the HSN Profile to provide practical cybersecurity guidance for commercial and non-commercial organizations and stakeholders engaged in the design, acquisition, and operation of satellite buses or payloads that involve HSN in a manner that is consistent with their risk tolerance.
