Secure Communication Channels (NET-005-R004) - NET-005

Requirement Details & Guidance

NET-005-R004 · NET-005

Why This Requirement Exists

Supports remote access, authentication, authorization, secure channels, third-party access and monitoring by ensuring that secure communication channels 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 secure communication channels, protect communications using approved secure protocols and cryptographic controls.
