NIST Special Publication 800-207 outlines the foundational concepts and guiding principles of Zero Trust Architecture (ZTA), a security model that assumes no implicit trust based on network location and emphasizes continuous verification of identity, access, and behavior. The report details a shift from perimeter-based security to resource-centric protection, driven by the proliferation of cloud services, mobile workforces, and advanced persistent threats. It provides a conceptual framework for ZTA, core components, deployment scenarios, and threat models, along with implementation guidance. This architecture supports dynamic and granular access control, minimizing the attack surface and improving resilience across complex digital ecosystems.
