Announcement
The Zero Trust Architecture (ZTA) team at NIST's National Cybersecurity Center of Excellence (NCCoE) has published volumes C and 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 implementations that align to the concepts and principles in NIST Special Publication (SP) 800-207, Zero Trust Architecture. As the project progresses, the preliminary draft will be updated and additional volumes will be released for comment.
A zero trust architecture (ZTA) focuses on protecting data and resources. It 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. Each access request is evaluated by verifying the context available at access time, including the requester’s identity and role, the requesting device’s health and credentials, and the sensitivity of the resource. If the enterprise’s defined access policy is met, a secure session is created to protect all information transferred to and from the resource. A real-time and continuous policy-driven, risk-based assessment is performed to establish and maintain the access. In this project, the NCCoE and its collaborators use commercially available technology to build interoperable, open, standards-based ZTA implementations that align to the concepts and principles in NIST Special Publication (SP) 800-207, Zero Trust Architecture. This NIST Cybersecurity Practice Guide explains how commercially available technology can be integrated and used to build various ZTAs.
