Announcement

Zero trust refers to an evolving set of network security paradigms that narrows defenses from wide network perimeters to individual resources. Its focus on protecting resources rather than network segments is a response to enterprise trends that include remote users and cloud-based assets that are not located within an enterprise-owned network boundary.

NIST invites comments on a second draft of NIST Special Publication (SP) 800-207, Zero Trust Architecture, which discusses the core logical components that make up a zero trust architecture (ZTA) network strategy. This second draft publication builds upon the first draft with a new section on zero trust approaches as well as updates to material based on public comments.

Abstract

Zero trust (ZT) is the term for an evolving set of cybersecurity paradigms that move network defenses from static, network-based perimeters to focus on users, assets, and resources. A zero trust architecture (ZTA) uses zero trust principles to plan enterprise infrastructure and workflows. Zero trust assumes there is no implicit trust granted to assets or user accounts based solely on their physical or network location (i.e., local area networks versus the internet). Authentication and authorization (both user and device) are discrete functions performed before a session to an enterprise resource is established. Zero trust is a response to enterprise network trends that include remote users and cloud-based assets that are not located within an enterprise-owned network boundary. Zero trust focus on protecting resources, not network segments, as the network location is no longer seen as the prime component to the security posture of the resource. This document contains an abstract definition of zero trust architecture (ZTA) and gives general deployment models and use cases where zero trust could improve an enterprise’s overall information technology security posture.
