Low Earth Orbit (LEO) satellite communication (SATCOM) services are expanding rapidly, offering new connectivity options but also introducing new cyber security risks.

ASD’s ACSC, together with the Australian Space Agency, the Canadian Centre for Cyber Security, the National Security Agency, and the New Zealand National Cyber Security Centre have released guidance to help organisations understand these risks and make informed decisions when procuring or using LEO SATCOM services.

The guidance outlines risks and mitigations across space, ground and user segments. It also highlights broader risks relating to communication links, supply chains and data management.

Organisations can also use the set of key questions when engaging with LEO SATCOM service providers to help assess their 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.

Read the full guidance to learn more about cyber security for LEO SATCOM systems.
