Full title and description

Space data and information transfer systems — Security architecture for space data systems. ISO 20214:2015 provides a high-level security architecture (SASDS) intended to help systems engineers understand layered security concepts and incorporate security considerations into the design of space data systems, using views aligned with the Reference Architecture for Space Data Systems (CCSDS).

Abstract

ISO 20214:2015 is a systems‑engineering reference that defines a Security Architecture for Space Data Systems (SASDS). It describes layered security concepts, a common vocabulary and views (derived from the CCSDS Reference Architecture) to communicate risks, requirements and solutions for securing space mission data systems, and to guide security architects during system design.

Scope

ISO 20214:2015 establishes a security reference architecture for space data systems; it is intended for use by CCSDS working groups, mission designers and security architects to describe and incorporate security into data system architectures and high‑level designs. The standard focuses on architectural views and security concepts rather than specific implementation or key management practices.

Key topics and requirements

• Definition of a Security Architecture for Space Data Systems (SASDS) and layered security concepts (end‑to‑end, link, on‑board, ground storage considerations).
• Use of architectural views derived from the CCSDS Reference Architecture for Space Data Systems to represent security concerns consistently.
• Common vocabulary and representation to communicate threats, risks and security requirements across mission stakeholders.
• Guidance for security architects to inform system security design — conceptual requirements and interfaces rather than prescriptive implementation or key‑management mechanisms.
• Interoperability orientation: designed to be used alongside CCSDS recommendations (for example, CCSDS cryptographic algorithm guidance adopted in ISO 20215).

Typical use and users

Primary users include systems and security architects, spacecraft systems engineers, mission designers, CCSDS working groups and organizations responsible for mission security assurance. Typical uses are: defining architecture-level security requirements, aligning mission designs with a common security framework, and informing development of mission-specific security implementations and standards harmonization.

Related standards

Relevant and closely related documents include the CCSDS/ISO Reference Architecture for Space Data Systems (ISO 13537:2010 / CCSDS RASDS) which supplies the architectural views used by ISO 20214, and ISO 20215:2015 (Space data and information transfer systems — CCSDS cryptographic algorithms) for recommended cryptographic primitives and modes applicable to space missions. Additional CCSDS security and mission‑specific key management recommendations complement ISO 20214.

FAQ

Q: What is this standard?

A: ISO 20214:2015 is an international standard that provides a Security Architecture for Space Data Systems (SASDS) — a high‑level reference architecture and vocabulary for incorporating security into space data systems.

Q: What does it cover?

A: It covers architectural concepts, layered security approaches and the use of CCSDS architectural views to represent security requirements and solutions across mission data systems. It does not prescribe detailed key‑management procedures or low‑level cryptographic implementations.

Q: Who typically uses it?

A: Systems and security architects, spacecraft and ground‑segment engineers, mission designers and standards bodies (including CCSDS and ISO/TC 20/SC 13) use it to align security design at the architecture level.

Q: Is it current or superseded?

A: ISO 20214:2015 was published in August 2015 and, per the ISO record, was last reviewed and confirmed in 2023; the ISO record indicates this edition remains current. Users should check their national adoption notices for any country‑specific updates or transpositions.

Q: Is it part of a series?

A: Yes — ISO 20214 belongs to the family of ISO/CCSDS space data and information transfer systems standards (for example ISO 13537:2010 — Reference Architecture for Space Data Systems — and ISO 20215:2015 — CCSDS cryptographic algorithms). It is intended to be used in conjunction with CCSDS guidance and other ISO space‑systems documents.

Q: What are the key keywords?

A: Security architecture, space data systems, SASDS, CCSDS, layered security, telemetry, telecommand, cryptography, space systems (ICS 49.140).
