What is the importance of network segmentation in cybersecurity?

Network segmentation is important for cybersecurity because it helps to enhance security by dividing a network into smaller segments or subnetworks. This practice restricts the ability of cyber threats to move laterally within a network, thereby reducing the potential impact of breaches. By implementing network segmentation, organizations can contain breaches within isolated segments, limiting the scope of an attack and preventing it from spreading to other parts of the network. This approach also allows for better monitoring and control of network traffic, improves overall network performance, and makes it easier to apply specific security measures to different segments based on their security requirements.
