Space Segment Guidance

Security categorization anchors every later control. The spacecraft program should map each information type, for example, command authentication keys, real-time payload data, and housekeeping telemetry, to confidentiality, integrity, and availability impact ratings. Use concrete mission consequences, such as loss of uplink control causing potential vehicle tumbling, to justify High impact for command data while labeling routine, delayed science products as Low for availability. Record the rationale in the System Security Plan and ensure the same categories flow into ground-segment packages so both ends of the link follow a common protection baseline.
