Australia Issues Cybersecurity Guidance for LEO Satellite Communications
Summary
An Australian-led 2026 guide details cybersecurity risks and mitigations for low Earth orbit satellite communications, covering space, ground, user, link and supply-chain security, data management, sovereignty and provider assessments.
Key points
- The guide was authored by the Australian Signals Directorate’s Australian Cyber Security Centre with Australian, Canadian, New Zealand and US partner agencies.
- It examines risks across satellite, ground, user and supply-chain components, as well as communication links and data management.
- Highlighted threats include jamming, spoofing, command injection, compromised credentials, phishing, insecure software and supply-chain tampering.
- Recommended safeguards include encryption and authentication, MFA, network segmentation, continuous monitoring, patching, incident-response planning and resilient communications.
- The guidance urges users and providers to plan for post-quantum cryptography and consider secure data handling across borders, including sovereign routing and data localisation.
- It provides questions organisations can ask providers about security controls, monitoring, supply-chain assurance, compliance and shared responsibilities.

- Scope
- Cybersecurity risks and mitigation strategies for LEO satellite communications, including space, ground, user, communications-link, supply-chain, and data-management security.
- Recommendations
- Enforce multi-factor authentication, strong access controls, network segmentation, and regular patching.
- Use strong encryption for communications and stored data, with robust key-management practices.
- Continuously monitor satellite, ground, and communications-link activity for anomalies.
- Request software and hardware bills of materials and supplier assurance, including component traceability.
- Regularly test and update incident-response and continuity plans for satellite-service loss or compromise.
