risks if an attack occurs. For instance, network segmentation plays a vital role in
reducing the risk of a cyber breach by isolating it. Explain the following:
What does network segmentation mean; compare it to its flat network
counterpart.
Mention at least two of the best practices for network segmentation (i.e., what
should be considered when segmenting an organization's network)?
