RESEARCH TRIANGLE PARK, N.C.—The International Society of Automation (ISA) and the ISA Global Cybersecurity Alliance have released a new guide for consensus-based automation cybersecurity standards. 

“Automation cybersecurity standards are crucial in this increasingly connected world,” Mary Ramsey, ISA executive director said in the announcement. “The ISA/IEC 62443 Series of Standards leads the way as the world’s only consensus-based standards that focus on automation cybersecurity. One goal of the ISA Global Cybersecurity Alliance is to raise awareness of these standards and encourage their adoption across a wide range of industries.” 

The new guide, “Quick Start Guide: An Overview of the ISA/IEC 62443 Series of Standards,” now available for download, provides a high-level view of the objectives and benefits of these standards, as well as easy-to-use explainers on how to navigate them. The guide explores how and why IT and OT/ICS need unique types of protection against cyber threats and offers the latest recommendations on patch management. 

It also answers some of the most common questions about the ISA/IEC 62443 Standards, including:

  • Why is this series important? 
  • What are the benefits of using the standards? 
  • How are IT and ICS systems different? 
  • Which documents are part of the series and how can I use them to find what I need? 
  • Where can I find the current best practices around patch management? 

 

The ISA Global Cybersecurity Alliance’s Advocacy and Adoption work group coordinated the development of this guide, authored by Johan Nye, an independent consultant specializing in industry control systems and cybersecurity. During his 38-year career, Nye has designed ICS system architectures; created company standards and policies; implemented major ICS projects; supported ICS site engineers; and contributed to the design of several ICS products.

“We are grateful to the ISAGCA Advocacy and Adoption work group and Johan Nye for distilling these standards into a user-friendly formation that can be shared widely,” Ramsey said.
