Comment Period Extension for NIST HPC Security Overlay

The initial public draft (IPD) of NIST Special Publication (SP) 800-234, High-Performance Computing (HPC) Security Overlay, is available for public comment with a new due date for submitting public comment of August 4, 2025.

High-performance computing (HPC) systems provide fundamental computing infrastructure for large-scale artificial intelligence (AI) and machine learning (ML) model training, big data analysis, and complex simulations at exceptional speeds. Securing HPC systems is essential for safeguarding AI models, protecting sensitive data, and realizing the full benefits of HPC capabilities.

This NIST Special Publication introduces an HPC security overlay that is designed to address the unique characteristics and requirements of HPC systems. Built upon the moderate baseline defined in SP 800-53B, the overlay tailors 60 security controls with supplemental guidance and/or discussions to enhance their applicability in HPC contexts. This overlay aims to provide practical, performance-conscious security guidance that can be readily adopted. For many organizations, it offers a robust foundation for securing HPC environments while also allowing for further customization to meet specific operational or mission needs.

The public comment period is open through August 4th, 2025.
