Satellite networks rely on ground stations and control links for communications and navigation, so cyber controls must protect availability and commands.

Background for this topic.
Satellites are spacecraft used for communications, navigation and timing, Earth observation, or scientific missions, together with their ground stations, control systems and radio links. Their security depends on more than the vehicle in orbit: mission software, supply chains, telemetry and command channels, and terrestrial networks are all part of the operational system. Availability and command integrity can be safety- or mission-critical, while some payloads handle sensitive communications or location data.
Material risks include unauthorized commands after compromise of a ground system, jamming or spoofing of radio signals, and vulnerabilities in onboard or ground software. Appropriate controls include authenticated and encrypted commands, strict separation of control networks, careful key management, signed and tested updates, and monitoring for abnormal telemetry or access. Operators also need vulnerability management and rehearsed recovery plans that account for limited patching opportunities, long communication delays, and the need to preserve safe operation if links or ground facilities are unavailable.

Ground Stations a Top Target in Any Future Conflict, Warns Intelligence OfficialSpace is becoming a domain of warfare, with private sector companies' planet-side infrastructure on the front lines - and the first shots will likely be fired in cyberspace, a senior U.S. intelligence official warned this month. "If someone owns the ground station, they own the satellite."
Space Policy and Tech Head Paul Liias on Dealing With Satellite VulnerabilitiesA major disruption of civil and military satellites could cause chaos on the ground to communications, navigation and other vital services. But the threats don't just come from missiles. They also comes from hackers who could exploit numerous vulnerabilities, said Estonia's Paul Liias.
Firm Allegedly Embedded DDoS at the Request of a Foreign ClientA South Korean company exported 240,000 satellite receivers with distributed denial-of-service attack capabilities, leading to the arrest of its CEO by the Korean National Police Agency. The company and its employees face criminal prosecution for allegedly violating South Korea’s cybersecurity laws.
