What is the primary goal of network segmentation?

The primary goal of network segmentation is to contain security breaches and limit access within a network. By dividing a larger network into smaller, isolated segments, organizations can control traffic flow and apply specific security measures to each segment. This isolation means that if a breach occurs within one segment, it is much more difficult for the attacker to move laterally across the network to other segments, thereby minimizing the potential impact of the breach.

Segmentation also allows for more granular access controls, meaning that only authorized users can access certain segments of the network according to their roles or needs. This principle of least privilege reduces overall risk by restricting access to sensitive data and systems.

While increasing network speed, simplifying management, and enhancing user interface functionality are beneficial aspects of networking, they do not address the critical aspects of security that segmentation directly targets. Hence, the true strength of network segmentation lies in its ability to both contain potential threats and enforce access controls, thereby bolstering overall network security.
