标准摘要
[中文适用范围]： 本文档介绍了空间数据系统的安全参考架构，旨在为数据系统架构和高级设计中的安全性描述提供一种标准化方法，各个工作组可以在 CCSDS 内使用该方法。 [外文原描述]： ISO 20214:2015 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 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 representation 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 in a consistent way so that any standard can be used with other appropriate standards in a system.
