Hello everyone and welcome to my land.
Ethical Hacking course powerful.
So in this poll we're going to look at a network the basics of a network and also the penetration testing.
So when you want to actually attack a network we're going to have to break it down into three different
steps.
So the pre-K connection are a tax that can be done before connecting to a specific network.
Once we've done that we can try and break the Wi-Fi key.
So in the UK the most common of age and Beattie now these were used to BPA wpa 2 which is more secure
to BP is is old it's outdated it's not very secure but I will show an example of each one.
They're all breakable.
And once you've got that Wi-Fi Kate and we actually connect to the specific hotspots or router we can
do something called a post access attack or just a basic attack on a because we've got access.
We can just do many many different attacks which we will look at.
Well to give you a basic understanding of how a network is all connected together and network is just
a number of devices connected together for a purpose of sharing resources and transferring data.
So it applies to both Wi-Fi and wired connections it works very similar except the only difference is
suppose wireless and no wireless
one device in most Wi-Fi networks is the router.
So I'm going to refer to this as the server and then the shared data is the Internet.
So if you look at this picture we've got computer one computer two on computer three they're all connected
to a specific router on this router is then connected to the Internet.
So say you're on computer one in this network and you go to the web browser when that computer in a
network or in this case in this network needs to access the shared resources which was the Internet
it will send a request to the router.
So this is the shared resources.
This is the computer that you're on in the network.
So this is a network inside this box and this is the server.
So when you're typing Google Dakota UK on click enter that will send a request to the router.
Then once the router acknowledges that request it will send it to the Internet.
Then the Internet will actually send a response back which then the router receives and then therefore
sends the response to the computer one of those having the internet or the browser web site being displayed.
Now the most important part of all this and this was very very basic but the most important part we
need to focus on is the packets so all of these requests are responses I was talking about was transferred
as packets in Wi-Fi networks.
So these packets are sends just through the air and these packets will include sensitive information
and we need to capture these.
So to do so we're going to look at changing the wireless card and their wireless mode.
So change in the wireless mode on a wireless card and also how to change a MAC address for a specific
wireless card.
So hopefully this just give you a basic understanding before we actually start penetration testing and
network so subscribe like this video if it did help please leave any comments and I'll be happy to help.
And I will see you in the next video.
