NIST SP 800-207
NIST SP 800-207 is the authoritative US government publication defining Zero Trust Architecture — its principles, components, deployment models, and implementation scenarios.
⚙️ How Does It Work?
The document describes the seven tenets of Zero Trust, the logical components of a ZTA (Policy Engine, Policy Administrator, Policy Enforcement Point), and three migration scenarios from perimeter-based to Zero Trust.
📍 Where Is It Used?
US federal agencies implementing Zero Trust (per OMB M-22-09 mandate), enterprises using NIST as their Zero Trust reference framework.
💡 Real-World Example
A federal agency references NIST 800-207 to design its Zero Trust implementation: deploying Entra ID as the Policy Engine, implementing device compliance checks, and using Zscaler as the Policy Enforcement Point.
