Network Architecture Standards (NET-001-R005) - NET-001

Requirement Details & Guidance

NET-001-R005 · NET-001

Why This Requirement Exists

Supports network architecture, trust boundaries, security zones, design governance by ensuring that network architecture standards is governed and implemented consistently, reducing unauthorized access, network attack exposure, service disruption, and security control gaps.

Implementation Guidance

Document the required control objective and scope; assign an accountable owner; define approved standards and configurations; implement the control across applicable network environments; integrate it with monitoring and change management; retain evidence; and review effectiveness periodically. For network architecture standards, define, document, and govern the security design.
