In what scenario is policy segmentation particularly useful?

Policy segmentation is particularly useful in scenarios aimed at preventing lateral movement of attackers within a network. This approach involves creating distinct security policies for different segments of the network, which makes it more difficult for an adversary who has gained access to one area to move freely throughout the entire network. By isolating sensitive data and critical applications, and applying specific access controls tailored to each segment, organizations can limit exposure and mitigate the risk of a full-scale breach.

While securing Wi-Fi networks, enhancing user experience, and increasing application load times are important considerations in network management and security, they do not directly align with the primary focus of policy segmentation. The main goal of this segmentation method is to bolster security by creating barriers that hinder the movement of potential intruders, thereby reinforcing the overall cybersecurity posture of the organization.
