In cybersecurity, one strategy that often goes underappreciated is network segmentation. This approach involves dividing an organization’s IT network into multiple zones or segments, each with its own access controls and policies. It’s a practical method for minimizing risk and containing potential breaches.
Segmented networks make it harder for threats to move laterally within an environment. If an attacker gains access to one segment, they can’t easily reach sensitive systems in another. This layered protection is particularly valuable when working with data subject to federal regulations, such as Controlled Unclassified Information (CUI).
Organizations handling CUI often adopt strict security practices. One solution is to isolate these sensitive processes within a CMMC enclave. Enclaves offer a dedicated space that is segmented from the rest of the corporate network, reducing exposure and simplifying compliance with frameworks like NIST 800-171 and CMMC.
In addition to better security, segmentation can aid in troubleshooting, performance optimization, and policy enforcement. Whether it's a full enclave setup or a simpler internal zoning plan, the principle remains the same: separation enhances control.
