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.
