What is the primary benefit of network segmentation?

The primary benefit of network segmentation is that it makes it harder for attackers to access the whole network. By dividing a network into smaller, isolated segments, organizations can contain potential breaches and limit the lateral movement of threats. If an attacker gains access to one segment, they cannot easily infiltrate others without overcoming additional security measures. This containment strategy helps protect sensitive information and critical systems by adding layers of security that can mitigate the impact of a security incident.

Moreover, segmentation can help enforce access controls, ensuring that users only access the resources necessary for their role, further reducing the attack surface. This tactical approach not only enhances security but also reinforces compliance with regulatory standards that require data protection. Network segmentation is a vital practice in secure software design, as it supports the principle of least privilege and strengthens an organization's overall cybersecurity posture.
