IEC 62351 Cybersecurity Standards

Description

The scope of the IEC 62351 series is information security for power system control operations. The primary objectives are two-fold:

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.
Undertake the development of standards and/or technical reports on end-to-end security issues.

Specific objectives include:

IEC 62351-1 provides an introduction to the remaining parts of the standard, primarily to introduce the reader to various aspects of information security as applied to power system operations.
IEC 62351-3 to IEC 62351-6 specify security standards for the IEC TC 57 communication protocols. These can be used to provide various levels of protocol security, depending upon the protocol and the parameters selected for a specific implementation. They have also been design for backward compatibility and phased implementations.
IEC 62351-7 addresses one area among many possible areas of end-to-end information security, namely the enhancement of overall management of the communications networks supporting power system operations.
Other parts are expected to follow to address more areas of information security.
