What Is Network Segmentation?

Network segmentation is a cybersecurity practice that involves dividing a computer network into smaller, isolated subnetworks or segments.

This process is carried out to improve the overall security, performance, and manageability of the network.

By creating these separate segments, organizations can limit unauthorized access to sensitive data, control the spread of malware or cyberattacks, and reduce network congestion.

Network segmentation can be achieved using various techniques, such as VLANs (Virtual Local Area Networks), firewalls, or access control lists.

Implementing network segmentation is a critical component of a robust cybersecurity strategy, as it helps protect valuable assets and maintain the integrity of an organization’s network infrastructure.
