Top 8 Network Segmentation Best Practices in 2024 | UpGuard

This article explains network segmentation as a defense-in-depth strategy to divide a flat network into smaller zones (via VLANs, firewall rules, or SDN) to limit attack surface, contain malware spread, and prevent lateral movement. It lists the benefits of segmentation and presents eight practical implementation recommendations — continuous monitoring and audits, balanced segmentation (avoid over/under-segmentation), limiting third-party access, inventorying and labeling assets, grouping similar resources, deploying endpoint protection, enforcing least privilege/zero-trust, and designing efficient legitimate data paths — while noting implementation challenges and trade-offs.
