01Definition
Space cybersecurity is the practice of protecting space systems, across the space, ground, link, and user segments, from cyber threats.
Space cybersecurity covers defending satellites, ground stations, the links between them, and the users who depend on the service. It combines traditional security operations with the specific constraints of operating and protecting systems in space.

- Ground segment: The ground segment is the part of a space system on Earth: the ground stations, networks, and control systems that command satellites and receive their data.
- Resilience engineering: Resilience engineering, in the space context, is the practice of designing space systems so they keep operating through failure, interference, and attack.
