Abstract A zero trust architecture (ZTA) enables secure authorized access to enterprise resources that are distributed across on-premises and multiple cloud environments, while enabling a hybrid workforce and partners to access resources from anywhere, at any time, from any device in support of the organization’s mission. This NIST Cybersecurity Practice Guide explains how organizations can implement ZTA consistent with the concepts and principles outlined in NIST Special Publication (SP) 800-207, Zero Trust Architecture. The NCCoE worked with 24 collaborators under Cooperative Research and Development Agreements (CRADAs) to integrate commercially available technology to build 19 ZTA example implementations and demonstrate a number of common use cases. The Guide includes detailed technical information on each example ZTA implementation, providing models that organizations can emulate. The guide also summarizes best practices and lessons learned from the implementations and integrations to make it easier and more cost-effective to implement ZTA. Additionally, this guide includes mappings of ZTA principles and technologies to commonly used security standards and guidelines.
