The second amendment to the international standard IEC 62351-3 includes, among other things, that support for TLS-versions 1.0 and 1.1 is optional in order to avoid known weaknesses, as well as updating the handling of TLS-versions during renegotiation and reengagement. In addition, the text has been adapted to clarify communication relationships and to offer improvements to security events in coordination with IEC 62351-14. The changes in line with the current state of the technology ensure that the safety requirements placed on the system management of power engineering can be met.
