NIST SP 800‑82 is a cybersecurity overlay that adapts the NIST Special Publication 800‑53 controls for use in industrial control system and operational technology environments. While NIST SP 800‑53 was designed primarily for IT systems subject to federal security requirements, many of its controls do not account for the performance, reliability, and safety constraints of ICS networks. NIST SP 800‑82 addresses this gap by identifying which security controls are applicable to OT and how they should be implemented safely. The framework helps organizations protect critical industrial systems while maintaining operational integrity, supporting a risk‑based approach to cybersecurity that aligns with federal guidance and the unique needs of industrial environments.
