Network Segmentation

Definition - What does Network Segmentation mean?

Network segmentation is the idea of creating sub-networks within a corporate or enterprise network or some other type of overall computer network. Network segmentation allows for the containment of malware and other threats, and can add efficiency in terms of network performance.

Techopedia explains Network Segmentation

One excellent example of network segmentation involves placing an internal firewall inside a network. Engineers then segment the two different sides of that firewall into specific sub-network areas. For example, data can go into the first sub-network environment and be scanned for malicious code before it progresses through the firewall to the other side of the network.

Another big use for network segmentation is to route data in the most efficient and effective ways. In order to optimize workflows, engineers may only send certain kinds of data through a particular network segment, either to improve security, or to cut out unnecessary traffic that puts pressure on network hardware or requires more resources. Vendors are using new products and services to bring efficiency and versatility to client networks through network segmentation, and it is having an impact in the IT industry.
