Tiffany Harbour: NIST for OT Security. What 800-82, CSF 2.0, and 800-53 Mean for OT Environments

Описание: NIST is referenced in almost every OT security conversation. But what does it actually mean for a plant, substation, water facility, or industrial site where uptime and safety come first?

In this episode of OT Insights, Ed sits down with Tiffany Harbour to break down how NIST guidance really applies to operational technology environments. This is not a compliance discussion. It is a practical conversation about using NIST to make better architectural and program decisions in OT.

We cover the three NIST efforts that matter most for OT security:

NIST SP 800-82
The foundation for understanding OT architecture, segmentation, and operational constraints. This is the document that reflects how industrial environments actually work.

NIST Cybersecurity Framework 2.0
A program and communication backbone that helps OT, IT, and leadership align around outcomes like Identify, Protect, Detect, Respond, and Recover.

NIST SP 800-53
A broad control catalog that can support OT security when used selectively and intelligently, not as a rigid mandate.

Key topics in this episode
How to use 800-82 to drive real OT architecture decisions
Why segmentation in OT is about containment, not perfection
How CSF 2.0 helps structure and communicate the OT security program
Why detection in OT starts with understanding normal process behavior
Where 800-53 helps and where it can create operational risk
How to use NIST as a decision tool instead of a compliance checklist

This episode is designed for OT leaders, plant managers, engineers, and security teams who need to balance cybersecurity with safety, reliability, and production.

If NIST only shows up in your audits and reports, you are underusing it. This conversation will help you turn NIST into a practical advantage in your OT security program.
