What is the primary goal of network segmentation?

The primary goal of network segmentation is to enhance security and performance by isolating different network segments. This approach improves security by limiting the ability of attackers to move laterally within the network; if one segment is compromised, others remain protected. It helps contain the impact of potential security incidents by controlling access to sensitive data and resources.

Additionally, network segmentation can optimize performance by reducing congestion and allowing for tailored resources for different segments of the network. For example, segments can be dedicated to specific departments or applications, ensuring that high-demand services do not interfere with baseline network performance.

In contrast, improving internet connectivity for users does not align with the primary intention of segmentation, which is deeper than merely enhancing access to external networks. Consolidating all network traffic into a single channel would negate the benefits of segmentation by creating bottlenecks and increasing vulnerability, rather than improving security and performance. Increasing the complexity of network configurations does not serve a beneficial purpose and could lead to management challenges and increased risk of misconfigurations. Thus, focusing on isolation for enhanced security and performance is the foundational goal of network segmentation.
