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.

The public comment period for this document is open through March 13, 2020. See the publication details for a copy of the document and instructions for submitting comments.

NOTE: A call for patent claims is included on page iv of this draft. For additional information, see the Information Technology Laboratory (ITL) Patent Policy--Inclusion of Patents in ITL Publications.
