Requirement Details & Guidance

ARC-006-R009 · ARC-006
Why This Requirement Exists

This requirement exists to periodically assess Zero Trust controls against established criteria and best practices and to ensure security architecture decisions are consistent, risk-informed, and traceable.

Implementation Guidance

Establish a documented process for periodically assess Zero Trust controls against established criteria and best practices. Define accountable roles, required inputs and outputs, approval or validation points, criteria, review frequency, exception handling, monitoring, and evidence requirements. Integrate the activity with architecture governance, risk management, security requirements, engineering, and change processes as applicable. Retain records sufficient to demonstrate that the control operates.
