Wireshark Basics (3)

In this final video of the Wireshark Basics series, we will look at a more advanced traffic analysis using Wireshark. For this exercise we will once again fire Nmap, but this time use its OS and Service Fingerprinting scan and try and figure out its workings using the packet traces generated. The take away from this video is how to trace a TCP connection and look at the actual data exchanged between a client and server pair. As a specific example we will look at HTTP server type detection using Nmap. We will also trace the network dump for the "It Works!" page of Apache :)
