What is meant by the term 'network segmentation'?

The term 'network segmentation' refers to the practice of dividing a larger network into smaller, manageable segments or sub-networks. This process enhances overall network performance and security by limiting the scope of broadcast traffic and improving response times. By separating segments, organizations can better control the flow of data and resources, restrict access to sensitive information, and isolate issues without affecting the entire network.

For security perspectives, segmentation can help contain potential breaches. If an attacker gains access to one segment, they would need to bypass defenses to reach other parts of the network. This principle is fundamental in designing secure networks, as it helps to enhance both performance and security.

Other choices do not accurately represent the concept of network segmentation. Creating a backup of network configurations deals with data recovery and redundancy; consolidating devices into a single network suggests an opposite approach to segmentation; and implementing a firewall is a specific security measure that can be used in conjunction with segmentation but does not inherently define the concept itself.
