What is the aim of network segmentation in cybersecurity?

The primary aim of network segmentation in cybersecurity is to isolate network segments to enhance security. By creating distinct segments within a network, organizations can control traffic flow between different areas, applying tailored security policies and access controls specific to each segment's requirements. This localized control minimizes the risk of lateral movement by an attacker, meaning if one segment is compromised, the threat can be contained and does not easily spread to other critical areas of the network.

In addition, segmentation can aid in compliance with various regulations by ensuring that sensitive data is kept within specific boundaries where enhanced security measures can be enforced. This focused segmentation helps in mitigating the impact of potential breaches and strengthens overall cybersecurity posture.
