3.3.3 IEC 62351 (Power systems management and associated information exchange – Data and communications security)

3.3.3.1 Focus

The scope of the IEC 62351 series is information security for power system control operations. The primary objective is to undertake the development of standards for security of the communication protocols defined by IEC TC 57, specifically the IEC 60870-5 series, the IEC 60870-6 series, the IEC 61850 series, the IEC 61970 series, and the IEC 61968 series.

The figure below presents an overview of IEC 62351 parts, as well as the mapping of IEC 62351 standards to IEC TC 57 communication standards.

3.3.3.2 Associated Evaluation Scheme and Governance

IEC 62351-100-1, currently under development, aims at specifying common available procedures and definitions for conformance and/or interoperability testing of the IEC 62351-5, the IEC 608705-7 and their recommendations over the IEC 62351-3. These are the security extensions for IEC 60870-5 and derivatives.

3.3.3.3 Process

Under development.

3.3.3.4 Practice

Not known. 

3.3.3.5 Relation to other standards / schemes

IEC 60870-5 and its derivatives, IEC 60870-6 (TASE.2), and IEC 61850.
