AEROSPACE REPORT NUMBER: TOR-2011-8591-22, SPACE SEGMENT INFORMATION ASSURANCE (IA) GUIDANCE FOR MISSION SUCCESS (10-JUN-2011)., This guide describes existing governance, guidance, and standards in the area of Information Assurance, as applied to National Space systems, and describes how all three � governance, guidance and standards � are in flux. The guide also provides a mission assurance context in which the role of IA techniques can best be understood, and addresses what must be done to go beyond the conventional techniques of IA if true mission resilience is to be achieved. The central chapters of the guide provide explicit guidance for the acquisition, development, update, and operation of National Space systems, focusing specifically on the Space Segment of those systems, as defined herein � the notion of the Space Segment is expanded somewhat beyond typical usage. The guide adapts IA guidance primarily developed for conventional ground-based information systems, focusing that guidance on the ability of the Space Segments of National Space systems to support mission resilience in an actively contested Cyberspace environment. Since the means for achieving both information assurance and mission assurance for the Space Segment of National Space systems are in such flux in the highly dynamic domain of Cyberspace, the guide also identifies some areas where unresolved challenges remain and future work will be required.
