Welcome to footprinting and scanning.
I'm Josh Mason.
And I'll be your instructor for this part of the course.
In this section, we're going to start thinking and acting
like an adversary.
Now, the first steps adversary is
going to take when they get hands on with the network
and thus, your first steps when you get hands
on with the network, are going to be mapping that network out
and then running port scans to find
vulnerable services that you can possibly
exploit for remote execution.
There's going to be some basics that I'm not going to cover.
I'm going to assume that you've seen the previous videos
and you understand a little bit about networking, at least
what's been already covered.
We're also going to get a little bit into some Linux.
We'll start off on the command line.
And if you have no idea what we're doing,
pay attention, try it out, learn a little bit,
and you'll get more comfortable with time.
Promise.
By the end of this section, you should understand purpose
and the reason behind network mapping, port scanning,
and you should be able to do it yourself.
Now, we're going to get hands-on with some networks.
And if you don't have permission from network owners to run
these tools or do these techniques, then don't.
You can get in serious trouble or there could be
repercussions on that network.
So if you don't have permission, don't touch it.
With that, we'll start digging in.
