Designing Secure Space Systems

Abstract

As space exploration advances and the commercialization of space technologies expands, ensuring the security of space as- sets has become a paramount concern. A key factor contribut- ing to this challenge is the growing reliance on off-the-shelf hardware and software. While such components accelerate the adoption and commercial use of space technologies, they also introduce new vulnerabilities and broaden the attack surface. This paper highlights the critical importance of integrating security concepts throughout the entire design lifecycle of space systems. It examines key dimensions of secure space system development, including secure engineering practices, comprehensive testing methodologies, strategies for cyber re- siliency, and the role of standardization in fostering a con- sistent and robust security posture across the industry. By addressing these essential aspects, the paper underscores the need for a holistic, lifecycle-driven approach to safeguarding space systems against evolving cyber threats.
