What is the purpose of network segmentation?

The purpose of network segmentation is to divide a larger network into smaller, more manageable parts, which significantly enhances security and control over data access. By isolating different segments of a network, organizations can apply specific security policies tailored to the needs and risks associated with each segment. This isolation limits the potential impact of a security breach, as unauthorized access or malware spread can be contained within a segment rather than affecting the entire network.

Moreover, different segments can be configured with additional layers of security, allowing for more precise monitoring and control over traffic flow. This practice makes it easier to comply with regulatory requirements and internal security policies, as sensitive data can be better protected within its designated area of the network.

In terms of performance, while segmentation can yield benefits by reducing congestion and improving efficiency for specific components, it is not primarily aimed at enhancing performance for all users. Therefore, the emphasis is on security and access control rather than simply on management simplicity or the combination of various security protocols.
