8、on) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be re

9、presented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards

10、are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internati

11、onal Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

The Committee meets periodically

18、 to address data systems problems that are common to all participants, and to formulate sound technical solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary, the results of Committee actions are termed Recommendations and are not in themselves considered bindin

19、g on any Agency. CCSDS Recommendations take two forms: Recommended Standards that are prescriptive and are the formal vehicles by which CCSDS Agencies create the standards that specify how elements of their space mission support infrastructure shall operate and interoperate with others; and Recommen

20、ded Practices that are more descriptive in nature and are intended to provide general guidance about how to approach a particular problem associated with space mission support. This Recommended Practice is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommended

21、 Practice is entirely voluntary and does not imply a commitment by any Agency or organization to implement its recommendations in a prescriptive sense. No later than five years from its date of issuance, this Recommended Practice will be reviewed by the CCSDS to determine whether it should: (1) rema

22、in in effect without change; (2) be changed to reflect the impact of new technologies, new requirements, or new directions; or (3) be retired or canceled. In those instances when a new version of a Recommended Practice is issued, existing CCSDS-related member Practices and implementations are not ne

23、gated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such Practices or implementations are to be modified. Each member is, however, strongly encouraged to direct planning for its new Practices and implementations towards the later version of the Recom

24、mended Practice.

38、document is intended as a high-level systems engineering reference to enable engineers to better understand the layered security concepts required to secure a space system. As such, this document is a Security Architecture for Space Data Systems (SASDS). This architecture uses the views described in

39、 the Reference Architecture for Space Data Systems (reference B1) developed by the CCSDS Architecture Working Group. The SASDS will be used: to establish an overall CCSDS conceptual framework for the incorporation of security into the data systems of space missions; to define common language and rep

40、resentation so that risks, requirements, and solutions in the area of security within space data systems can be readily communicated; to provide a source of information for the security architects on a space mission to use to develop the system security design; to facilitate development of standards

41、 in a consistent way so that any standard can be used with other appropriate standards in a system. 1.1.2 SCOPE This document presents a security reference architecture for space data systems and is intended to provide a standardized approach for description of security within data system architectu

42、res and high-level designs, which individual working groups may use within CCSDS. For further information regarding securitys role in space systems, the reader is directed to the supporting CCSDS documentation listed in annex B.

44、ection 2 provides an introduction into how the security architecture uses the Reference Architecture for Space Data Systems (RASDS). Section 3 discusses the security concepts that need to be addressed by any security architecture. Section 4 examines the security concepts and shows how the CCSDS arch

45、itecture outlined in sections 2 and 3 relate to each other. Section 5 establishes high-level principles and the scope that the security architecture addresses. Section 6 illustrates a series of mission profiles which help identify where security is required, what the issues are, and what solutions a

46、re applicable. Section 7 specifies the security reference architecture.
