Zero Trust in OT: Adapting IT's Playbook for Enhanced Security

Industrial Cybersecurity Insider

Dino Busalachi and Jim Cook, the CTO and COO of VELTA Technology respectively, discuss the intersection between IT (Information Technology) and OT (Operational Technology) in the cybersecurity landscape. They emphasize that, while IT security measures have their value, they cannot be applied as-is to the OT environment due to significant variations in system operations, scale, and impact in case of breaches.

They stress the importance of holistic consideration of operations when devising cybersecurity measures for OT. They cover topics like zero trust environments, asset inventory, key points from IT’s playbook that may be suited, and ones that would prove challenging in OT – security lessons that need to be adapted rather than employed directly.

They bring in the element of digital safety being just as important as physical safety in an OT environment considering the potential physical outcomes as a result of breaches. The conversation reveals a need for IT professionals to work in collaboration with their OT counterparts for more effective and robust cybersecurity systems, even as the two roles begin to diverge more explicitly in terms of responsibilities and strategies.
