ISA99 to Develop Security Profiles for Electric Energy Transmission and Distribution

  • Standards

ISA99, Industrial Automation and Control Systems Security, has established a new Working Group 14, “Security Profiles for Electric Energy OT Control Systems.” The working group will focus on a cybersecurity work product utilizing the ISA/IEC 62443 series of standards for securing various control systems used in electric energy generation, transmission, and distribution operations. 

This group will prioritize the development of multiple ISA/IEC 62443 security profiles for transmission and distribution applications. The initial priority will be on the control center and substations. These profiles should be adaptable or expandable to the control center and generation facilities. The third priority will be distributed applications. Profiles will provide ISA/IEC 62443 conduit requirements between the various process zones and mitigation requirements within a zone. The profiles will also provide mandatory and optional documentation requirements. The intent is to provide a means for auditing and testing deployments with respect to the requirements set forth in the ISA/IEC 62443 standards.

The scope of the project will include interface and communication exchanges to and from external levels that are identified and within the levels or zones in the various application environments.
