Fyodor gave me a heads up that Nmap 5 was coming out, so I figured I'd do a couple of videos on useful new features that come with Nmap 5 and later. For a better understanding of Nmap in general, check out my older videos which I will link to after the presentation. In this video I will cover the basics of using NDiff to compare two seperate Nmap scans. This is really useful for change management, where you want to know what new devices have appeared on your network or about ones that have disappeared for some reason. You could easily schedule Nmap to run on your network weekly, and then compare the differences with NDiff to see what has changed.
