How can network segmentation enhance security?

Network segmentation enhances security primarily by isolating network segments. This means that individual parts of the network can be separated from one another so that if one segment becomes compromised or faces a security threat, it doesn't automatically compromise the entire network. By isolating sensitive systems and segments, organizations can contain potential breaches and limit attackers' access to other parts of the network.

This added layer of separation makes it more difficult for unauthorized users or malware to traverse the network, which not only helps protect sensitive data but also ensures that any security issues can be contained more effectively. For example, if a segment handling payment transactions is breached, other segments dealing with internal communications remain intact and secure.

While increasing bandwidth, simplifying network management, and eliminating the need for firewalls may have their own benefits in network operations, they do not directly contribute to enhancing security in the same impactful manner as isolating network segments.
