IEC TR 62351-90-1:2018

IEC TR 62351-90-1:2018 addresses guidelines for handling role-based access control in power systems, helping organizations structure access rights in a way that supports secure operations and controlled information exchange. Based on the official title, it is relevant where data and communications security must be evaluated alongside operational needs, engineering documentation, and compliance workflows. For teams responsible for technical review, procurement assessment, or security validation, the document offers a focused reference for understanding how access control concepts may be applied in power system environments.

Overview of IEC TR 62351-90-1:2018

The title indicates a technical report within the IEC 62351 series, with particular attention to role-based access control for power systems and associated communications. IEC TR 62351-90-1:2018 is therefore most useful as a guidance-oriented technical document for organizations reviewing security architecture, user permissions, and control of operational access. It can support engineering specification work, documented evaluation, and technical assessment where access management is part of a broader cybersecurity or system integration review.

Compliance applications of IEC TR 62351-90-1:2018

In compliance workflows, this reference may be used when defining or reviewing access control policies for utility automation, substation communications, control centers, or other power-system-related digital environments. It can also support testing workflows that examine whether role definitions and permission handling are consistent with organizational security requirements. For procurement and conformity assessment preparation, IEC TR 62351-90-1:2018 provides a relevant basis for comparing vendor documentation, checking implementation assumptions, and aligning operational controls with internal risk management objectives.

Importance of compliance with IEC TR 62351-90-1:2018

Following the guidance in IEC TR 62351-90-1:2018 can improve operational consistency by clarifying how access rights are assigned, reviewed, and controlled within power systems. This is important for reducing unauthorized access risk, supporting safe operation, and strengthening technical validation during engineering review or laboratory evaluation. It may also help organizations prepare for procurement decisions, quality assurance checks, and conformity assessment activities by providing a structured basis for evaluating role-based access control practices in security-sensitive environments.
