How can network segmentation enhance security?

Network segmentation enhances security primarily by isolating different segments of the network, which limits access and reduces the risks associated with potential breaches. This approach means that if one segment of the network is compromised, the threat can be contained within that segment, preventing it from affecting the entire network.

By effectively controlling which users or devices have access to specific segments, organizations can enforce stricter security policies tailored to the needs and sensitivities of different areas of the network. For instance, sensitive data or critical infrastructure can be placed in separate segments with enhanced security measures, while less sensitive operations can remain more accessible. This not only helps in protecting sensitive information but also simplifies the task of monitoring and managing security protocols across the network.

In contrast to the other options, increasing bandwidth for all devices doesn’t directly correlate with security, and consolidating security protocols doesn't inherently limit access or provide isolation. Furthermore, enabling remote access for all users could actually pose a security risk rather than enhance it, as it opens up more potential pathways for unauthorized access. Thus, the correct view is that network segmentation is a strategic approach to bolster security by restricting and monitoring access across various parts of the network.
