NASA-STD-1006 is a NASA technical standard used on applicable programs and projects to define protection requirements that support mission resilience. In practice, it tells engineers what safeguards, design constraints, and verification steps are needed so a system can keep operating, recover safely, or fail in a controlled way when faced with cyber or operational stress.
In cyber security, standards like this matter because space systems are not protected by hardware alone. They depend on flight software, ground control, communications links, timing services, and navigation inputs. NASA-STD-1006 helps turn that complexity into enforceable requirements for securing interfaces, limiting unsafe states, and planning for interference or degradation. Defenders use it to guide architecture reviews, control selection, and test coverage. Attackers may try to exploit weak links in command paths, ground dependencies, or navigation functions, so resilience-focused standards are meant to reduce the impact of jamming, spoofing, configuration drift, and unauthorized control.
