Cybersecurity Principles for Space Systems
This Space Policy Directive-5 establishes cybersecurity principles for U.S. space systems, directing executive agencies to foster practices that protect government and commercial space assets from cyber threats. It mandates risk-based, cybersecurity-informed engineering for space systems throughout their lifecycle, with specific requirements for encryption, access protection, jamming/spoofing defenses, supply chain security, and information sharing. The directive applies to government national security space systems, civil space systems, and private space systems.
