What is the purpose of network segmentation?

Network segmentation is a strategy used to divide a larger network into smaller, more manageable sections or segments. The primary purpose of this practice is to enhance both security and performance within the network.

By separating the network into segments, organizations can control and restrict access between different areas. This makes it more difficult for unauthorized users to move laterally within the network, improving overall security. For instance, if a breach occurs in one segment, it can be contained without affecting the entire network. Furthermore, segmentation can help isolate sensitive data or critical systems, ensuring they are protected from potential threats.

In terms of performance, network segmentation can reduce congestion and improve traffic flow. By limiting broadcast traffic and distributing it across segments, each segment can operate more efficiently, leading to better overall network performance. This focused approach allows for tailored policies and monitoring, ensuring resources are used effectively.

Other options do not address the core functions of network segmentation. Limiting access to the Internet is more about firewalls and access control mechanisms. Creating more user accounts does not relate to network performance or security. Increasing physical server space is unrelated to the logical design and security architecture of the network. Thus, the focus on improving security and performance is what truly defines the purpose of network segmentation.
