IEC 61850 Security – Siemens SIPROTEC 5

Siemens published an informative document on Security of their communication systems supporting IE 61850, IEC 60870-5-103, DNP3 etc:

SIPROTEC 5 Application Note
Communication Architecture Under Cyber Security Aspects

I was a bit surprised that the IEC 61850-8-1 (MMS) communication in SIPROTEC 5 IEDs is not secured. The paper even does not mention the IEC 62351 series … which at least recommends to apply TLS for the TCP communication and MMS.
