Network Segmentation: Divide and Conquer Your Network

Network segmentation is the process of dividing a computer network into smaller segments or sub-networks in order to improve network performance, reduce network congestion, and increase security. Network segmentation involves the use of various technologies such as routers, switches, firewalls, and virtual LANs (VLANs) to create multiple sub-networks within the larger network. This allows for the creation of separate, isolated networks that can be used for specific tasks or applications, while still allowing the larger network to remain connected. By segmenting a network, it is possible to control access to resources, provide enhanced security, and improve overall network performance. Additionally, segmentation can help to reduce the risk of malicious attacks, such as distributed denial of service (DDoS) attacks, by isolating the vulnerable parts of the network. Network segmentation can also be used to provide better quality of service (QoS) for certain applications or services, such as VoIP or video streaming, by reserving a portion of the network for their exclusive use.
