NIST has released the initial public draft of NIST Special Publication (SP) 800-82r3, Guide to Operational Technology (OT) Security, which provides guidance on how to improve the security of 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:
