What is the significance of network segmentation?

The significance of network segmentation lies primarily in its ability to limit access to sensitive data by creating isolated segments. This approach enhances security by dividing a network into smaller, manageable sections, which can be monitored and controlled independently. By isolating segments, organizations can enforce strict access controls, ensuring that only authorized users or systems can access sensitive information within those segments. This practice reduces the attack surface for potential intruders, as gaining access to one segment does not necessarily grant access to others. Additionally, if a security breach occurs within one segment, the impact can be contained without affecting the entire network, thereby protecting critical data and systems from widespread compromise. This layered security strategy is essential for maintaining data confidentiality, integrity, and availability.
