Types of Network Segmentation
1. Physical Segmentation
To physically segment a network, one has to plug different groups of devices into separate switches. Physical segmentation is the most secure choice, but it is also the most difficult to implement. Physical Segmentation is known as perimeter-based segmentation, each section requires its own internet connection, physical wiring, and a firewall. There are limited constraints on internal resources, which typically work over a flat network with minimal internal network partitioning. Physical segmentation is also quite unstable. Once hackers or malicious users have gained access to the firewall, they may move freely around the network with no or little restriction.
2. Virtual Segmentation
Virtual segmentation, also known as logical segmentation, refers to the division of a single physical network into multiple virtual networks or segments. These segments are logically isolated from each other, allowing for distinct communication and security policies to be applied to each segment. Virtual segmentation is often implemented using technologies such as VLANs (Virtual Local Area Networks).
What is Network Segmentation?
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.
