Which of the following is a benefit of network segmentation?

Network segmentation provides a key benefit in enhancing security by creating sub-networks within a larger network. This isolation helps to lower security risks in several ways. When a network is segmented, any potential issues that arise, such as a security breach or malware infection, can be contained within that specific segment rather than affecting the entire network. For example, if one part of the network is compromised, network segmentation prevents attackers from moving laterally to other segments, thereby protecting sensitive data and critical applications from exposure.

Moreover, segmentation allows for the implementation of tailored security measures in each segment, which can be designed to meet the specific needs and risks associated with that portion of the network. This targeted approach to security management promotes a more robust overall security posture for the organization.

The other options do not accurately reflect the primary advantages of segmentation. While increased data redundancy, unrestricted access to all users, and improved data accuracy are potential concerns in some network contexts, they are not benefits of segmentation. In fact, unrestricted access can lead to higher security risks, making segmentation particularly valuable in safeguarding critical information.
