Zero Trust Architecture in HPC and AI Environments

This presentation is based on a recently published paper - see https://ojs.library.carleton.ca/index.... The paper explores the application of Zero Trust Architecture (ZTA) principles to High Performance Computing Infrastructure (HPCI), which has become increasingly crucial for scientific, industrial, and AI workloads. Traditional cybersecurity frameworks like the ISO 27000-series and NIST 800-series have proven inadequate for the unique challenges posed by HPCI. The paper is informed by three regulatory frameworks: OMB Memo M-22-09, CISA's Zero Trust Maturity Model (ZTMM), and NIST Special Publication 800-223, which collectively shape the U.S. Federal Government's approach to ZTA in HPCI. The study assesses the compatibility of ZTMM with HPCI across five pillars, identifying potential challenges in balancing security, cost, complexity, and performance. The findings suggest that a "Traditional" maturity level is most suitable for HPCI, given its unique characteristics and operational demands.
