A command-and-control path is the communication route used to send authorized instructions to a satellite or other remote system. In space operations, this path usually runs through ground stations, network links, control software, and cryptographic protections before a command reaches the spacecraft. Because it carries operational authority, it is a high-value target: anyone who can alter, block, or impersonate this route may affect mission behavior.
In cyber security, attackers may try to abuse the command path by stealing credentials, tampering with ground-side systems, spoofing messages, or disrupting radio links with jamming or denial of service. Defenders protect it with strong authentication, key management, network segmentation, logging, and strict access controls. They also design fallback procedures, such as safe modes or alternate links, so the mission can remain trustworthy even if one part of the path is compromised.
