When I say identify, I'm talking about finding what operating systems and what applications are possibly running on that machine. We're going to do that with banner grabbing and OS fingerprinting.

The best way to sum up what this module is about was best phrased by the famous scholar Joey Tribbiani, who said, How you doin? That's exactly what we're doing here! We're trying to get to know the system. We're trying to identify the target. So, we'll go through and look at OS fingerprinting, which is the process of going through and identifying the operating system by the way that it responds to certain types of packets we're going to send to it.

Now, there's something else we can do called banner grabbing. This is...
