What does network segmentation aim to achieve?

Network segmentation aims to divide a network into smaller parts for improved security. This approach enhances security by isolating different segments of a network, which can prevent unauthorized access and contain potential breaches. When a network is segmented, it allows for more granular control over traffic and access permissions, making it easier to enforce security policies tailored to the specific needs of each segment.

For instance, if a breach occurs in one segment of the network, it becomes more challenging for an attacker to move laterally within the network to access sensitive data in other segments. By separating sensitive systems from less secure ones, organizations can better defend against cyber threats and minimize damage in case of an incident.

While integrating various networks into a single unit, enhancing overall network speed, or restricting user access to specific applications may have their benefits, these objectives do not directly relate to the primary goal of network segmentation, which focuses explicitly on improving security through division and isolation.
