What does network segmentation primarily aim to protect?

Network segmentation primarily aims to protect data integrity and confidentiality by creating distinct zones within a network that limit access based on specific security requirements. By segmenting a network, organizations can ensure that sensitive information is isolated from less secure parts of the network, which reduces the risk of unauthorized access or data breaches.

This practice allows for stricter access controls tailored to the sensitivity of the data flowing through each segment. For example, internal staff may have access to certain areas of the network while external vendors may only reach specific segments. Consequently, if one segment is compromised, the impact on the overall network is minimized. This is crucial in maintaining the integrity of data and ensuring that sensitive information remains confidential, thereby adhering to compliance regulations and organizational security policies.

Other choices, such as physical hardware assets, user experience, and network redundancy, while important aspects of a network’s functioning, are not the primary focus of network segmentation. The segmentation efforts are mainly concentrated on safeguarding the data that traverses the network and fortifying the network against various security threats.
