ISA Global Cybersecurity Alliance (ISAGCA) Releases White Paper on Zero Trust Model for Cybersecurity in OT and ICS

ISA Global Cybersecurity Alliance (ISAGCA) Releases White Paper on Zero Trust Model for Operational Technology and Industrial Control Systems

Durham, NC, August 14, 2024 – The ISA Global Cybersecurity Alliance (ISAGCA) has unveiled a groundbreaking white paper exploring the implications of the zero trust model in the realm of operational technology (OT) and industrial control systems (ICS).

The white paper, titled “Zero Trust Outcomes Using ISA/IEC 62443 Standards,” delves into the significance of incorporating zero trust principles in OT security. It highlights the use of the ISA/IEC 62443 series of standards as a framework for implementing zero trust strategies in critical infrastructure systems.

With safety being the top priority in OT security, the paper emphasizes the importance of aligning zero trust principles with essential functions outlined in ISA/IEC 62443. It warns against disrupting critical safety functions while implementing zero trust architecture, particularly in fault-tolerant systems.

While acknowledging the additional costs associated with zero trust implementation, the paper underscores the long-term benefits of enhanced security measures and organizational strategy. It also suggests hybrid approaches to integrating zero trust principles where full implementation may not be feasible, enhancing detection and response capabilities in OT networks.

“Zero Trust Outcomes Using ISA/IEC 62443 Standards” is now available for download on the ISAGCA website, providing valuable insights for cybersecurity professionals and stakeholders in the OT and ICS sectors.

ISAGCA is renowned for its efforts in advancing OT cybersecurity awareness and standardization, with over 50 member companies driving innovation and best practices in the industry. Learn more about ISAGCA and the ISA/IEC 62443 series of standards at www.isagca.org and www.isa.org.
