What does network segmentation help with?

Network segmentation is a crucial technique in cybersecurity that involves dividing a computer network into smaller, isolated segments or sub-networks. The primary purpose of this practice is to enhance the security of the organization by controlling access to sensitive data and reducing the attack surface.

When a network is segmented, it becomes easier to manage and enforce security policies. For instance, if an attacker gains access to one segment, they may not automatically have access to others, thereby containing the potential damage. Additionally, it allows organizations to implement more stringent security measures in segments that contain sensitive information, such as customer data or intellectual property, while applying less stringent controls in less critical areas.

This containment approach helps minimize the impact of a security breach, as unauthorized access can be limited to only a small part of the overall network. Moreover, segmenting networks enables better monitoring and response to threats, as security professionals can focus their attention on particular segments that may be at risk. As a result, overall security is significantly strengthened when organizations adopt network segmentation practices.
