AI Data Center Security Analysis: Draft SP 800-239 Available for Public Comment
July 27, 2026

NIST invites public comments on the initial public draft (ipd) of Special Publication (SP) 800-239, AI Data Center Security Analysis: A High-Performance Computing (HPC) Driven Approach, which examines the security landscape of artificial intelligence (AI) data centers. 

Building upon established principles from high-performance computing (HPC) threat analyses and security overlays, this publication delivers a thorough threat and security gap analysis for purpose-built AI infrastructure used in model training, inference, and applications. By contrasting AI data centers with traditional HPC systems across architecture, hardware, software stacks, workflows, and storage systems, the publication pinpoints critical security threats and outlines possible solutions to safeguard next-generation AI environments.

The public comment period is open through September 25, 2026. See the publication details for a copy of the draft and instructions for submitting comments. 

NOTE: A call for patent claims is included in this draft. For additional information, see the Information Technology Laboratory (ITL) Patent Policy – Inclusion of Patents in ITL Publications.
