Does IEC 61850 provide Security Measures? - Yes

Some people had a concern that IEC 61850 does not define security measures. This is only half-way correct.

The fact is that IEC 62351 defines the Security for IEC 61850! IEC 61850 references IEC 62351. So, don't worry. Even the Beck Chip for IEC 61850 provides standard security.

IEC 62351-3:
Data and communications security: Communication network and system security – Profiles including TCP/IP

IEC 62351-4:
Data and communications security: Profiles including MMS

Part 3 specifies how to secure TCP/IP-based protocols through constraints
on the specification of the messages, procedures, and algorithms of Transport Layer Security (TLS) (defined in RFC 2246) so that they are applicable to the telecontrol environment of IEC TC 57. It is intended that this specification be referenced as a normative part of other IEC TC 57 standards that have the need for providing security for their TCP/IP-based protocol.

Part 4 specifies procedures, protocol extensions, and algorithms to facilitate
securing ISO 9506 – Manufacturing Message Specification (MMS) based applications. It is intended that this technical specification be referenced as a normative part of other IEC TC 57 standards that have the need for using MMS in a secure manner.
This technical specification represents a set of mandatory and optional Security specifications to be implemented for applications when using ISO/IEC 9506 (Manufacturing Message Specification).
