What is Network Segmentation Used for?
Network segmentation has several benefits for organizations. It does not have a single purpose, but primarily it is used to organize networks. Segmentation also allows for more efficient use of bandwidth by reducing the size of broadcast domains and getting rid of unnecessary traffic on the network. Another benefit of having a segmented network is that it enhances security by reducing an organization’s attack surface by not keeping all computers in the same network space. When you separate a network, all outbound and inbound traffic has to go through a layer-3 device, a router, and a firewall if there is one. If one team wants to contact another team over a network, the traffic passes through the router and firewall. Thus, segmentation gives a little more control to the organization over the traffic because the firewall can do things like deny unnecessary traffic.

In computer networking, segmentation is an important idea to improve the security and performance of the network. In other words, Network segmentation is the idea of creating subnets within a network or networks within a network. In this article, we are going to discuss network segmentation.
