What is the purpose of network segmentation in a security strategy?

Network segmentation plays a critical role in enhancing security and controlling network traffic. By dividing a larger network into smaller, distinct segments, an organization can effectively limit access and exposure to sensitive information. For example, if an attacker gains access to one segment, the impact can be restricted, reducing the risk of a broader network compromise. This approach also allows for implementing tailored security measures for each segment based on its specific risk profile and needs.

Segmentation limits the pathways through which unauthorized users can navigate, allowing for precise monitoring and control of traffic between segments. It enhances the overall security posture by containing potential threats, thus preventing them from spreading across the entire network. This practice not only mitigates risks but also aids compliance with various security regulations that require strict access control measures.

In summary, the primary purpose of network segmentation within a security strategy is to bolster defenses against threats while also providing better control over the flow of data and access within the organization’s network.
