Open for Public Comment: Preliminary Draft Practice Guide (Vol A-E) From the ZTA Team

The Zero Trust Architecture (ZTA) team at NIST’s National Cybersecurity Center of Excellence (NCCoE) has published the second version of volumes A-D and the first version of volume E of a preliminary draft practice guide titled “Implementing a Zero Trust Architecture” and is seeking the public’s comments on their 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.

The updated versions of volumes A-D document three additional ZTA implementations that have been added to the guide since the previous drafts were published. Volume E provides a risk analysis and mapping of ZTA security characteristics to cybersecurity standards and recommended practices. As the project progresses, the guide will be updated.

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.

We Want to Hear from You!

The NCCoE is making volumes A-E available as preliminary drafts for public comment while work continues on the project. Review the preliminary drafts and submit comments online on or before February 6, 2023.
