Requirement Details & Guidance

CLD-005-R001 · CLD-005
Why This Requirement Exists

This requirement reduces risk in cloud network security by ensuring network security framework is defined, consistently implemented and demonstrably effective across cloud environments. It supports the organization's need to secure cloud-based assets, data and services while managing cloud-specific risk.

Implementation Guidance

Implement documented controls for network security framework within segmentation, firewalls, secure connectivity, traffic protection and network visibility. Define scope, ownership, required evidence, monitoring, review cadence and escalation criteria; automate validation where practical.
