IEC 62351 - Power Systems Communication Security
The IEC TC 57 series securing power system communication protocols (IEC 60870-5, DNP3, ICCP, IEC 61850) and adding end-to-end functions: TLS profiles, MMS security, telecontrol authentication, GOOSE and SV authentication, network and system management, role-based access control, key management and XML file security, with technical reports on security architecture, DER resilience, the security topics standards should cover and deep packet inspection of encrypted traffic.
IEC 62351 - Power Systems Communication Security is a compliance framework from International (IEC TC 57 WG15); adopted as EN IEC 62351 with 14 domains and 75 controls that map to 274 other frameworks. The largest domains are Part 3: profiles including TCP/IP (TLS) – IEC 62351 - Power Systems Communication Security (13 controls), Part 9: cyber security key management – IEC 62351 - Power Systems Communication Security (9 controls), Part 5: security for IEC 60870-5 and derivatives – IEC 62351 - Power Systems Communication Security (8 controls). Every control below carries what it requires and what an assessor expects to see.
