The EU Space Act establishes a separate sectoral resilience and cybersecurity regime—distinct from NIS 2—applicable to all space actors. Draft Articles §75–78 require operators to implement cybersecurity risk management systems, perform continuous threat assessments, and participate in the Union Space Resilience Network (EUSRN) for incident reporting and coordination WIRED+7Space | Tech | Law+7Space Economy Institute+7Redditnoerr.com.

Why It Matters

CubeSat platforms increasingly rely on COTS processors, ground segment APIs, and open RF links—exposing them to growing electronic threats. The Act makes cybersecurity foundational to authorization. Even startups and small operators must meet minimum baseline standards in access control, cryptography, patching, and incident response—failure means regulatory risk, potential fines (up to 2% of global turnover), and mission reputational damage.

Technical & Organizational Checklist

• Cyber Risk Management System (CRMS):
• Asset inventory and threat modeling for satellite and ground components
• Secure boot, firmware signing, OTA patching mechanisms
• Encryption in command and telemetry paths
• Operational Resilience Measures:
• Redundant communication nodes or fallback ground stations
• Anomaly detection logs and escalation procedures
• Crisis communication and response plans integrated into EUSRN workflows
• Incident Reporting & Audits:
• Define thresholds for “significant incident” reporting to EUSPA
• Support for regulatory audit access
• Continuous verification logs and evidence retention (>5 years)

Scenarios & Recommendations

Commercial Imaging Provider

Challenge: Need to safeguard sensitive payload bus and telemetry paths from spoofing or jamming. Recommendation: Prioritize encrypted command uplinks, dual authentication login for ground ops, and intrusion detection telemetry channels.

Academic CubeSat with Open API Payload

Challenge: Research payload exposes open interfaces and data feeds. Recommendation: Ensure sandboxed API isolates command domains and include logging hooks with session records; threat model external access and accidental misuse.

Multi-Customer Integration Platform

Challenge: Integrator supports payload modules for various missions with differing trust levels. Recommendation: Create standardized compliance modules and integration controls; ensure each client payload routes through certified CRMS tooling.
