Security Principles (ARC-001-R002) - ARC-001

Requirement Details & Guidance

ARC-001-R002 · ARC-001

Why This Requirement Exists

This requirement exists to establish foundational security principles that guide architecture decisions consistently and to ensure security architecture decisions are consistent, risk-informed, and traceable.

Implementation Guidance

Establish a documented process for establish foundational security principles that guide architecture decisions consistently. 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.
