Announcement
This initial public draft provides guidance on how to improve the security of Operational Technology (OT) systems while addressing their unique performance, reliability, and safety requirements.
OT encompasses a broad range of programmable systems or devices that interact with the physical environment (or manage devices that interact with the physical environment). These systems/devices detect or cause a direct change through the monitoring and/or control of devices, processes, and events. Examples include industrial control systems (ICS), building automation systems, transportation systems, physical access control systems, physical environment monitoring systems, and physical environment measurement systems.
This third revision of SP 800-82 provides an overview of OT and typical system topologies, identifies typical threats to organizational mission and business functions supported by OT, describes typical vulnerabilities in OT, and provides recommended security safeguards and countermeasures to manage the associated risks.
Updates in this revision also include:
- Expansion in scope from ICS to OT
- Updates to OT threats and vulnerabilities
- Updates to OT risk management, recommended practices, and architectures
- Updates to current activities in OT security
- Updates to security capabilities and tools for OT
- Additional alignment with other OT security standards and guidelines, including the Cybersecurity Framework (CSF)
- New tailoring guidance for NIST SP 800-53, Rev. 5 security controls
- An OT overlay for NIST SP 800-53, Rev. 5 security controls that provides tailored security control baselines for low-impact, moderate-impact, and high-impact OT systems.
