In this chapter, we took a look at CS, which allows you to view and analyze packet captures in a browser. We learned that CS provides several ways of examining captures that are similar to Wireshark.

We discovered that, in general, there are many resources for packet captures that you can visit and download a file to study and improve your packet analysis skills. We then took a look at PacketLife, which has an online repository of capture files for download, or an option to open them and analyze them in CS.

We saw that, with CS, you can filter a capture to show only a specific type of traffic, as well as creating a variety of graphs. In addition, CS has a rich variety of analysis tools that include Follow Stream, network endpoints, a GeoIP world map, packet lengths, DNS activity, VoIP calls, wireless networks, and threat assessments.
