A space station is a structure designed for people to live and work in orbit. It is a cyber-physical system: computers, networks, sensors, robotics, communications links, and life-support equipment all have to work together with very limited room for error. Commands may come from ground control, while telemetry, scientific data, and crew systems move through tightly managed channels.
Space stations matter to cyber security because disruption can affect both safety and mission continuity. Attackers might try to interfere with command authentication, telemetry integrity, software updates, or the ground segment that talks to the station. Defenders reduce risk with segmented networks, strong access control, signed commands, redundant systems, careful patching, and continuous monitoring of onboard and ground-side components. In practice, securing a space station means protecting not just the hardware in orbit, but the entire chain of software and communications that keeps it operational.
