Cybersecurity in Space

Cybersecurity in the space domain has become a critical global concern due to the growing reliance on satellite systems for communication, navigation, Earth observation, and national security. As space infrastructures evolve into highly interconnected and software-defined ecosystems, they face increasing exposure to sophisticated cyber threats, including signal interference, data breaches, unauthorized access, and cyber-physical attacks.

This book provides a concise yet comprehensive examination of cybersecurity challenges across modern space systems. It explores the foundations of space communication technologies and the evolving threat landscape affecting satellites, ground stations, and supporting infrastructures. The discussion extends to supply chain vulnerabilities, software-defined satellite networks, and resilience engineering approaches designed to strengthen mission security throughout the lifecycle of space operations.

The book also highlights advanced and emerging technologies for securing space environments, including machine learning–based threat detection, blockchain-enabled trust mechanisms, and quantum communication schemes for resilient cybersecurity. In addition, it addresses threat intelligence, incident response, governance, international policy, and global cooperation frameworks that support the safe and sustainable use of outer space.

Designed for researchers, policymakers, engineers, and industry professionals, this book combines theoretical foundations with practical insights to help secure next-generation space systems against evolving cyber risks.
