What networking strategy involves breaking LANs into small, highly localized zones?

Microsegmentation is a networking strategy that involves dividing a larger Local Area Network (LAN) into smaller, more manageable segments or zones. This practice enhances security by limiting access within individual segments, thereby reducing the attack surface and containing potential threats.

By creating highly localized zones, microsegmentation allows organizations to apply security policies specific to each segment. This means that even if an attacker gains access to one part of the network, their ability to move laterally to other segments can be significantly hindered.

Microsegmentation is particularly effective in environments where sensitive data is stored or processed, allowing for strict control over who and what can access different parts of the network.
