Understanding Network Segmentation for Data Protection

Network segmentation is the practice of dividing a network into smaller, isolated segments. This improves both performance and security by limiting how far threats can spread if a system is compromised.

In a segmented network, different departments or workloads can be assigned to separate zones. For example, HR systems might operate on a different network segment than production servers or financial databases. This separation creates security boundaries and makes monitoring easier.

By isolating sensitive data environments from general operations, segmentation also supports regulatory compliance efforts. One common approach involves setting up secure environments to store and process Controlled Unclassified Information (CUI).

This is where a CMMC enclave comes into play. These purpose-built environments are designed to meet the requirements for handling CUI while benefiting from segmentation best practices. They help limit exposure and keep critical assets insulated from broader network risks.

Network segmentation is an effective strategy for both large enterprises and smaller businesses looking to improve their cybersecurity defenses.
