Segmentation optimizes a computer network by controlling how traffic flows between its parts. That lets an administrator determine how this traffic should go. Depending on what a business needs and what its goals are, this can be done in various ways.

To properly understand something, it can be helpful to have an example. In a bank with several branches, management will need to restrict employees from accessing the financial reporting system. With network segmentation, a security professional will block traffic from each location from accessing that system.

That information, however, can still be accessed by officials at a given location, although these will only be appropriate individuals.

These are typically devices that don’t come with software or any kind of in-built protection. It can also be difficult, if not impossible, to install such software on many of these devices.

If these are properly segmented, however, then this software shouldn’t be able to reach the devices. Instead, it’ll be redirected to ones that have proper protection, if not outright cut off.
