CS406: Information Security

This video describes network segmentation, and how the networks can be segmented at the physical and data link layers. Networks can be segmented for many reasons: compliance, optimizing or improving performance, separating private communications from public, protecting legacy systems, creating testing environments, securing data flow, or creating honeynets. Pay attention to supervisory control and data acquisition (SCADA) systems and why they should be segmented. This video also discusses the Stuxnet virus. What type of system was it designed to attack?
