NIST SP 800-82 Rev. 3 — NIST Special Publication 800-02 Rev. 3 - Guide to Operational Technology (OT) Security

NIST SP 800-82 Rev. 3 is a guide to securing operational technology (OT), such as industrial control systems, transportation systems, and building automation systems. It includes an overview of OT systems and their topologies, explores common threats and vulnerabilities, and provides detailed security countermeasures to mitigate risks. The standard emphasizes the need to balance security with the unique performance, reliability, and safety needs of OT systems. This revision, finalized in September 2023, supersedes Rev. 2 and includes updates reflecting advancements in OT and emerging security challenges. It serves industries that rely on OT systems and aims to improve their resilience against cyber threats.
