Industrial Control Systems and Operational Technology in NIST Special Publication 800-82
In the world of industrial operations and automation, two acronyms often surface in conversations around process control and cybersecurity: Industrial Control Systems (ICS) and Operational Technologies (OT). This article aims to demystify the differences between ICS and OT, examining their unique characteristics, roles, and the critical importance of each in our increasingly connected and automated industrial landscape. Specifically, we’ll cover how a new revision to NIST 800-82 has moved from ICS to full-blown OT security and best practices.
