Open for Public Comment: NIST NCCoE Zero Trust Architecture Preliminary Draft Practice Guide (Vol D)


NIST’s National Cybersecurity Center of Excellence (NCCoE) has released the third version of volume D of a preliminary draft practice guide titled “Implementing a Zero Trust Architecture” and is seeking the public’s comments on its contents. 

This guide summarizes how the NCCoE and its collaborators are using commercially available technology to build interoperable, open standards-based ZTA example implementations that align to the concepts and principles in NIST Special Publication (SP) 800-207, Zero Trust Architecture. Volume D provides a functional demonstration plan, and the updated version includes demonstration results for ten builds.

As an enterprise’s data and resources have become distributed across the on-premises environment and multiple clouds, protecting them has become increasingly challenging. Many users need access from anywhere, at any time, from any device. The NCCoE is addressing these challenges by collaborating with industry participants to demonstrate several approaches to a zero trust architecture applied to a conventional, general-purpose enterprise IT infrastructure on-premises and in the cloud.

The NCCoE is making volume D available as a preliminary draft for public comment while work continues on the project. Review the preliminary draft and submit comments online by October 9th, 2023. Comments and questions for the team may be sent to We welcome your input and look forward to your comments.
