NIST 800-82

NIST 800-82 commonly refers to NIST Special Publication (SP) 800-82, a cybersecurity guide focused on industrial control systems (ICS) and operational technology (OT). It adapts general NIST security controls and practices to the specific needs and constraints of control systems used in manufacturing, utilities, and other industrial environments.

What NIST 800-82 covers

NIST SP 800-82 describes how to secure systems such as:

• Distributed control systems (DCS) and programmable logic controllers (PLCs)
• Supervisory control and data acquisition (SCADA) systems
• Manufacturing execution and process control networks
• Interfaces between OT networks and IT systems (for example, MES/ERP, historians)

The publication explains how to apply risk management and security controls from broader frameworks such as NIST SP 800-53 to ICS and OT. It addresses topics like network segmentation, remote access, monitoring, configuration management, and response planning in industrial environments.

Use in industrial and regulated environments

In manufacturing and other regulated operations, NIST 800-82 is often used as:

• A reference for defining security requirements for OT and ICS assets
• A way to tailor NIST SP 800-53 controls to control systems and plant networks
• Input to risk assessments and selection of Low, Moderate, or High security baselines
• A common language for coordinating OT and IT security teams

Organizations may use NIST 800-82 alongside other industrial cybersecurity standards, such as IEC 62443, to document and justify control selections and to keep risk treatment consistent across plants, systems, and projects.

What NIST 800-82 is not

• It is not a law or regulation by itself.
• It is not a certification program or audit checklist.
• It does not replace industry standards like IEC 62443, but can be aligned with them.

Common confusion

NIST 800-82 vs NIST 800-53: NIST SP 800-53 defines a broad catalog of security and privacy controls for information systems in general. NIST SP 800-82 explains how to interpret and apply those kinds of controls to industrial control systems and OT, including unique considerations such as safety, process availability, and legacy equipment.

Connection to baseline selection

When organizations select Low, Moderate, or High security baselines for OT and ICS, NIST 800-82 is often used to interpret which controls are feasible and appropriate for industrial systems. It helps translate general control expectations into plant-floor constraints, such as continuous operations, long equipment life cycles, and interactions with safety and quality systems.
