About This Course

This course examines the application of the IEC 62351 standard series to secure digital substation communications against cyber threats. It covers the technical mechanisms for protecting network traffic, application-level messages, legacy protocols, and implementing role-based access control. The content distinguishes between IT and OT security priorities, emphasizing the critical need for system availability in power utility environments. Participants will explore how these technical standards integrate with broader frameworks like IEC 62443 and NERC CIP compliance requirements.

Topics Covered:

  • IEC 62351 standard series architecture
  • Network traffic protection methods
  • Application-level message security
  • Legacy communication protocol retrofitting
  • Role-based access control in substations
  • IT versus OT security priorities
  • Digital substation communication protocols
  • NERC CIP compliance and technical evidence

Target audience: Protection & control engineers, substation automation engineers, SCADA/OT engineers, cybersecurity analysts moving into OT, and NERC CIP compliance staff who need to translate standards into engineering action.
