Full title and description

Power systems management and associated information exchange - Data and communications security - Part 2: Glossary of terms (IEC TS 62351-2:2008). This Technical Specification defines and collects the key terms used throughout the IEC 62351 series to support consistent use of security and communications terminology in power system information exchange and smart-grid contexts.

Abstract

IEC TS 62351-2:2008 provides a glossary of security- and communications-related terms referenced by the IEC 62351 family. It is intended as a working vocabulary for implementers, standards writers and system integrators working on data and communications security for power systems; terms are included where relevant references to original definitions by other standards bodies are available.

Scope

Defines and explains the principal terms used in the IEC 62351 series relating to data and communications security for power systems management and associated information exchange. The TS is not intended as a definitive vocabulary for all cybersecurity concepts (many of those terms are defined by other standards bodies); instead it collects terms relevant to the 62351 family and points to original definitions where appropriate. The publication is positioned as core reference material for Smart Grid information-security work.

Key topics and requirements

• Comprehensive glossary of security- and communications-related terms used in the IEC 62351 series (authentication, authorization, encryption algorithms such as AES, audit, availability, access control lists, etc.).
• Cross-references to original definitions in other standards where applicable (the TS points implementers to normative sources for specialized terms).
• Support for consistent terminology across IEC 62351 parts and related power-system communications standards to reduce ambiguity in specifications and implementations.
• Intended as a normative reference for standards writers, implementers and integrators working on secure data exchange in power-system automation and smart-grid applications.

Typical use and users

Used by standards developers, utilities, system integrators, grid cybersecurity architects, equipment vendors and test laboratories as a reference to ensure consistent use of security and communications terminology when specifying, implementing or auditing secure power-system communications. It is also useful in training and documentation to align cross-organizational understanding of terms.

FAQ

Q: What is this standard?

A: IEC TS 62351-2:2008 is a Technical Specification that provides a glossary of terms used by the IEC 62351 series, focused on data and communications security for power systems. It collects and references security and communications terminology to promote consistent usage across the series.

Q: What does it cover?

A: It covers terms and definitions relevant to cybersecurity and communications in power-system information exchange — for example authentication, authorization, audit, encryption terms (AES), access control concepts and other items used across IEC 62351 parts; it also points to original definitional sources where appropriate.

Q: Who typically uses it?

A: Standards writers, utilities, vendors, system integrators, cybersecurity architects, test labs and educators use it as a reference to align terminology in specifications, implementations and documentation for secure power-system communications.

Q: Is it current or superseded?

A: As published in August 2008 (Edition 1.0), IEC TS 62351-2 remains the referenced glossary part of the IEC 62351 family; IEC lists a stability date and the TS is still shown in the IEC catalogue and as part of the current series package. Users should check the IEC catalogue for the latest status or any replacements/amendments before relying on the TS for compliance decisions.

Q: Is it part of a series?

A: Yes — IEC TS 62351-2 is one part of the IEC 62351 series (power systems management and associated information exchange — data and communications security). The series contains multiple parts addressing profiles, protocol-specific security, role-based access control, NSM models, and related technical reports.

Q: What are the key keywords?

A: Key keywords include: cybersecurity, smart grid, glossary, data and communications security, IEC 62351, telecontrol, telemetering, authentication, authorization, encryption (AES), access control.
