What does implementing network segmentation primarily enhance?

Implementing network segmentation primarily enhances performance and security by dividing a larger network into smaller, isolated segments. This technique allows for improved management of traffic, reducing congestion and resource bottlenecks, which leads to better overall network performance.

From a security perspective, segmentation can limit the scope of potential attacks. By isolating sensitive systems or data sets, it becomes more difficult for unauthorized users or malware to traverse the entire network if they manage to compromise one segment. Effective segmentation also enables more controlled access to resources, as security policies can be tailored to each segment based on its specific requirements and vulnerabilities.

Other choices, while related to network management or performance, do not capture the primary objective of segmentation in the same way. User training and compliance focus on human factors that influence network security but do not directly stem from the implementation of segmentation. Similarly, while network segmentation can indirectly support performance optimization and improve external access through optimized routing, it is primarily recognized for enhancing security measures within the network itself.
