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.

ORNL says portable detector kit can separate real GPS signals from fake ones even at equal strength GPS spoofing, which sends fake satellite-like signals, and GPS jamming, which drowns receivers in noise, are increasingly serious problems. Researchers at Oak Ridge National Laboratory in Tennessee have created what they say is the most effective system yet for detecting GPS interference, which could help blunt such attacks.…

This is why the Viasat attack – rated one of the biggest ever – had little impact RSA Conference The Kremlin-backed cyberattack against satellite communications provider Viasat, which happened an hour before Russia invaded Ukraine, was "one of the biggest cyber events that we have seen, perhaps ever, and certainly in warfare," according to Dmitri Alperovitch, a co-founder of CrowdStrike and chair of security-centric think tank Silverado Policy Accelerator.…
