For what might we use the tool Kismet? You use the kismet tool in order to find and detect wireless devices. Explain the concept of segmentation and why it might be done. We divide a network into multiple smaller networks each acting as its own small network called a subnet. Here we can control the flow of traffic. We may do this to prevent unauthorized network traffic or attacks from reaching portions of the network we would prefer to prevent access. What risks might be present ...
