Full title and description

Power systems management and associated information exchange — Data and communications security — Part 10: Security architecture guidelines. This Technical Report (IEC TR 62351-10:2012) provides guidance on security architecture for power systems, describing essential security controls, security-related components and functions, and how these map to power system architectures to support secure deployment of generation, transmission and distribution systems.

Abstract

IEC TR 62351-10:2012 presents security architecture guidelines for electrical power systems and associated information exchange. It identifies and describes essential security controls and their interactions, and offers mapping between those controls and general system architectures used in power generation, transmission and distribution. The report is intended to help system integrators, architects and security practitioners design and deploy secure power system solutions in accordance with existing standards and best practices.

Scope

This Technical Report targets the description of security architecture guidelines for power systems based on essential security controls — i.e., security-related components and functions and their interaction. It provides relation and mapping of these security controls to general power system architectures to guide secure deployment of power generation, transmission and distribution solutions and to support application of relevant standards and best practices.

Key topics and requirements

• Definition and classification of essential security controls for power systems (confidentiality, integrity, availability, authentication, authorization, auditing).
• Security architecture components and functional building blocks (network segmentation, gateways, identity and key management, monitoring and logging).
• Mapping of security controls to typical power-system architectures and interfaces (SCADA/EMS, substation automation, distribution management).
• Guidance for secure integration of control systems, protocols and remote access mechanisms.
• Recommendations for risk-informed application of existing standards and security frameworks when designing system architectures.

Typical use and users

Primary users include system integrators, power-system architects, utility cyber-security teams, equipment vendors, consultants and standards committees. The report is used during architecture design, procurement specification, security assessments and integration planning to align power-system deployments with recognized security controls and practices.

Related standards

IEC TR 62351-10:2012 is part of the IEC 62351 family (data and communications security for power systems) and is intended to be used alongside other parts of the series (for example parts addressing glossary, communication protocol security, transport and application-level protections, and operational guidance). It is commonly referenced alongside standards and frameworks such as IEC 61850 (substation communications), ISO/IEC 27001/27002, NIST guidance, IEC 62443 (industrial control system security) and related IEC/TC 57 publications and technical specifications. Cross-referenced standards and guidance are typically used to implement the controls discussed in this TR.
