IEC TS 62351-5 ED2 - Security for IEC 60870-5 and derivatives

IEC TC 57 just published a new proposal to revise TR IEC 62351-5 and convert it into a standard:


Proposed revision of IEC TS 62351-5 ED2 and transformation of the TS into an IS (Power systems management and associated information exchange - Data and communications security - Part 5: Security for IEC 60870-5 and derivatives)

Excerpt from the background:

"... Since IEC TS 62351-5 was first published, IEC 60870-5-7 has been published defining specific security requirements for IEC 60870-5 protocols based on IEC TS 62351-5, while similar specific security requirements have been defined for IEEE Std. 1815 (DNP3). In addition, implementations have been undertaken by vendors. As a result, some issues with IEC TS 62351-5 were identified. At the same time, the security requirements for IEC 60870-5 have matured since these specifications were released as a Technical Specification. At this time, it is important to update these security requirements and convert them into an International Standard in order to ensure that implementations of IEC 60870-5 can include the appropriate security measures. ..."

Comments are expected by 2018-07-20 at the latest.
