STRA stands for Space Threat Response Architecture, an EU framework for coordinating responses to space-related threats. It is not a satellite control system itself; it is a governance and coordination layer that helps authorities assess incidents affecting space assets, ground systems, communications, and related services.
In cyber security, STRA matters because space operations depend on software, authentication, networks, and terrestrial control segments. An intrusion against a satellite operator, a ground station, or a Member State system can quickly become a wider security issue. STRA supports shared situational awareness, faster inter-agency coordination, and, where needed, policy responses such as restrictive measures. For defenders, it reflects the reality that space attacks are often hybrid events, combining technical compromise with strategic pressure.
