Network Segmentation Strategies for Enhanced Security and Performance

Organizations can employ a range of strategies—often in combination—to implement effective network segmentation, enhancing security, performance, and manageability. One of the most widely used methods is VLAN-based segmentation (Virtual Local Area Networks). VLANs enable the logical grouping of devices into separate broadcast domains, irrespective of their physical locations. Network switches are configured to assign ports to specific VLANs, permitting communication within the same VLAN while requiring a router or Layer 3 switch for inter-VLAN communication. This method is relatively easy to implement, especially in small to medium-sized networks, and is cost-effective as it leverages existing switch infrastructure.
