Summary
ASD's ACSC, in collaboration with the Australian Space Agency, Canadian Centre for Cyber Security, NSA, and New Zealand National Cyber Security Centre, has published guidance on cyber security risks associated with Low Earth Orbit (LEO) satellite communication services. The guidance covers risks across space, ground, and user segments, addressing communication links, supply chains, and data management. The document provides key questions organisations should ask LEO SATCOM providers to assess security measures and resiliency.
“If your organisation depends on LEO SATCOM for operations, remote connectivity or critical services, now is the time to review your risks and uplift your security.”
Organisations relying on LEO SATCOM for critical connectivity should review the guidance and use the provided key questions when evaluating current or prospective service providers. The intergovernmental nature of this guidance — spanning Five Eyes partners — indicates broad recognition that SATCOM supply chain and data management risks are a shared concern.
