Network Segmentation

Network segmentation divides your network into smaller, isolated segments to control traffic flow and limit the spread of security incidents. By separating your CUI environment from your general corporate network, guest network, and internet-facing services, you reduce the attack surface and contain potential breaches to a smaller area.

Effective segmentation uses firewalls, VLANs, and access control lists to enforce boundaries between segments. In a well-segmented network, an attacker who compromises a workstation on the general network cannot directly reach systems in the CUI enclave without passing through additional security controls.
