What is Cybersecurity in Space?

2025-09-05

AI Summary

Modern space information systems—including satellites, UAVs, and 5G air-to-ground links—underpin critical infrastructure (aviation, finance, meteorology) yet lack robust defenses against advanced cyber threats, exposing them to ground station intrusions, GPS spoofing, and supply chain compromises; moreover, no unified vulnerability database or standardized security testing framework exists. Method: This study systematically identifies eleven key research gaps in space cybersecurity and proposes a distributed, AI-driven, endogenous security framework based on multi-agent systems, integrating lightweight onboard intrusion detection, post-quantum cryptography, quantum key distribution, zero-trust architecture, and real-time impact assessment. Contribution/Results: The project delivers a five-year technology roadmap, advances open cyber-range development, and establishes trusted supply-chain governance mechanisms. It shifts the paradigm from reactive incident response to proactive resilience, providing both theoretical foundations and deployable technical blueprints for building an autonomous, self-healing, and robust space cybersecurity ecosystem.

Abstract

Satellites, drones, and 5G space links now support critical services such as air traffic, finance, and weather. Yet most were not built to resist modern cyber threats. Ground stations can be breached, GPS jammed, and supply chains compromised, while no shared list of vulnerabilities or safe testing range exists. This paper maps eleven research gaps, including secure routing, onboard intrusion detection, recovery methods, trusted supply chains, post-quantum encryption, zero-trust architectures, and real-time impact monitoring. For each, we outline the challenge, why it matters, and a guiding research question. We also highlight an agentic (multi-agent) AI approach where small, task-specific agents share defense tasks onboard instead of one large model. Finally, we propose a five-year roadmap: post-quantum and QKD flight trials, open cyber-ranges, clearer vulnerability shar ing, and early multi-agent deployments. These steps move space cybersecurity from reactive patching toward proactive resilience.
