Which NIST publication provides guidance for implementing Zero Trust Architecture?

The choice of NIST 800-207 is accurate because it specifically addresses the implementation of Zero Trust Architecture (ZTA). This publication provides a comprehensive framework and detailed guidance on how organizations can adopt a Zero Trust approach to enhance their security posture. Zero Trust Architecture is built on the principle that no user or system, whether inside or outside the network, should be trusted by default. Instead, verification is required from everyone trying to access resources within a network.

NIST 800-207 discusses various components and architectural models associated with Zero Trust, including identity verification, access controls, and continuous monitoring. It emphasizes the importance of segmenting data and resources as a means to bolster security. By following the guidelines in this publication, organizations can effectively implement the principles of Zero Trust and improve their defenses against modern cyber threats.

Other publications mentioned in the options focus on different aspects of cybersecurity. For instance, NIST 800-53 deals with security and privacy controls for federal information systems but does not specifically target the Zero Trust model. NIST 800-61 focuses on handling computer security incidents, while NIST 800-84 provides guidance for conducting security assessments but does not cover Zero Trust principles directly. Hence, NIST 800-207 stands out as
