Designing Secure Space Systems

As space exploration advances and the commercialization and militarization of space technologies expand, ensuring the security of space assets has become a paramount concern. A key factor contributing 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 cybersecurity 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 resiliency, and the role of standardization in fostering a consistent 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.
