TL;DR

This position paper identifies unique security challenges arising from the convergence of space systems and cyberspace, emphasizing threats to satellite-based ICT infrastructures like communications, GPS, and Earth observation. It proposes a framework for addressing these risks through integrated technological and policy solutions, advocating for dedicated security responsiveness in space-cyber systems.

ABSTRACT

Spaceborne systems, such as communication satellites, sensory, surveillance, GPS and a multitude of other functionalities, form an integral part of global ICT cyberinfrastructures. However, a focussed discourse highlighting the distinctive threats landscape of these spaceborne assets is conspicuous by its absence. This position paper specifically considers the interplay of Space and Cyberspace to highlight security challenges that warrant dedicated attention in securing these complex infrastructures. The opinion piece additionally adds summary opinions on (a) emerging technology trends and (b) advocacy on technological and policy issues needed to support security responsiveness and mitigation.

Motivation & Objective

• To address the lack of focused discourse on the distinct threat landscape of spaceborne systems within global cyberinfrastructures.
• To analyze the interplay between space and cyberspace in shaping new, complex security challenges for satellite-dependent systems.
• To highlight emerging technology trends that amplify vulnerabilities in space-cyber systems.
• To advocate for coordinated technological and policy interventions to enhance security responsiveness and mitigation strategies.
• To establish a foundation for future research and policy development in space-cybersecurity by identifying critical gaps and priorities.

Proposed method

• Conducts a conceptual analysis of the integration between space-based assets and cyber infrastructure, focusing on communication, surveillance, and navigation systems.
• Identifies attack vectors specific to space systems, such as uplink/downlink compromises, signal spoofing, and orbital cyber-physical attacks.
• Proposes a security framework emphasizing resilience, authentication, and end-to-end integrity for space-cyber systems.
• Integrates insights from cryptography and systems security to address threats across the space-cyber attack surface.
• Advocates for policy reforms and standardization to support secure deployment and operation of space-based systems.
• Uses a position paper format to synthesize current knowledge and propose forward-looking recommendations for research and governance.

Experimental results

Research questions

• RQ1 What are the unique threat vectors that emerge when space systems are integrated into global cyberinfrastructures?
• RQ2 How do traditional cybersecurity models fail to address the specific vulnerabilities of spaceborne assets?
• RQ3 What technological and policy measures are necessary to ensure resilience and responsiveness in space-cyber systems?
• RQ4 How can emerging technologies like quantum communications and AI be leveraged to secure space-cyber interfaces?
• RQ5 What institutional and regulatory frameworks are required to support coordinated security responses across space and cyber domains?

Key findings

• Spaceborne systems such as communication satellites, GPS, and Earth observation platforms are increasingly critical to global cyberinfrastructures but remain under-protected against emerging threats.
• The convergence of space and cyberspace creates new attack surfaces, including signal spoofing, uplink manipulation, and cyber-physical attacks on satellite control systems.
• Current cybersecurity models are insufficient for space systems due to long latency, limited on-orbit patching, and high-value targets.
• A dedicated security framework is needed that integrates cryptographic hardening, real-time monitoring, and resilient command architectures.
• Policy and regulatory coordination across nations and agencies are essential to ensure consistent security standards and rapid incident response.
• Emerging technologies such as quantum key distribution and AI-driven anomaly detection show promise but require tailored integration into space-cybersecurity strategies.
