How does network segmentation contribute to enhanced security?

Network segmentation significantly enhances security primarily by limiting access to sensitive information. This technique involves dividing a larger network into smaller, isolated segments, each with its own security controls and policies. Doing so helps prevent unauthorized access to sensitive data by creating barriers between different parts of the network. If a breach occurs in one segment, the attacker may be contained within that area, thereby reducing the risk of widespread exposure of sensitive information.

By implementing segmentation, organizations can enforce stricter access controls and monitoring on segments that handle sensitive data, such as customer information or financial records. This focused approach means that only authorized personnel or systems can access these segments, minimizing the attack surface and enhancing overall security.

In contrast to the other options, while network speed, remote access, and network management can be benefits of segmentation, they do not directly relate to security enhancement in the primary sense. Therefore, the attribute of limiting access to sensitive information is the most critical aspect of how network segmentation contributes to improved security.
