Using Wireshark to find NMAP port scanning on your network.

A deep dive into more techniques for finding NMAP port scans in a packet capture with Wireshark. We walk through two packet captures and find the NMAP scans within them. This is a great way to learn Wireshark to find port scans and even just to learn Wireshark in general. Plenty of stuff for beginners, and everyone else too.
