And welcome back into this video we'll be discussing about the virtual private network, no virtual
private network with the Alterio for as the Libyan basically allows us to rout the traffic from your
network to the destination through the VPN server.
Now, it is something similar to the proxy.
Now, this can be understood with a simple example where you have your computer and you have their destination
server and the Internet, not your computer, which is connected to the Internet, would have a unique
IP address.
So your laptop or a computer, when you connect to the destination or the destination server, will
have full access logs related to your connection.
Details.
Now, in the case of a VPN or what happens here is that let's say that this is a VPN server and this
VPN server has the IP address of 54, 20, 30, 56.
Now, when you send the traffic via the VPN, their destination so it can be over the Internet, this
destination server will not see your IP address here.
It will see the IP address of the VPN because it is the VPN, which is routing all the traffic all.
Now, there are a lot of advantages and also there are a lot of use cases where a doctor uses VPN extensively
for the attack.
So let me quickly give you in the morning how exactly this might look like.
So this is a cyber ghost VPN.
This is pretty famous.
Now, if you see where this VPN server, as we see in this light, this can be selected like you want
it from us or you want it from Europe or you want it from Singapore, etc..
So if I can quickly show you, you can select various locations over here.
So if I click on more servers, you see there are a lot of servers which are available from the United
States to Vietnam to France, Germany, Australia, etc., etc..
Now, let's do one thing.
Let me just click on Connect so I will be connected to the VPN server.
So let's quickly wait for a moment here.
Great.
So I'm connected to the VPN server residing in Canada.
So now what happens?
My laptop or my computer is in India and the VPN server is in Canada.
Now, if I browse the Internet, the destination server will assume that the connection is coming from
Canada and hence the details would be chosen accordingly.
So let's try.
Let's put Google dot com and let's put what's my IP?
So the IP address in this 71 page, if you just open up one of the websites here, you see it ensuring
that the IP addresses ceridwen and it is showing the country as Canada, the region as Alberta.
And this is how the VPN works at a high level of, you know, when used cases are in fact a multiple
use cases can be achieved with the help of the bin Laden is that if you are connected to an insecure
network, let's say a public wireless hotspot, then it is better never to directly access it.
You should always connect the VPN in such cases.
The second reason why people typically use VPN is to unblock certain blocked websites.
So if I can quickly show you there's a website, Golez nine Gagnier TV.
All right.
So now what is happening is that it is redirecting to nine Gay.com nine.
I'm sure a lot of people might be using it.
So if you type nine gathered from the Indian ISP, you will see that the website is specifically blocked.
But since that I am connecting to a VPN, that website is unlocked for me.
Don't use case as something which ataca uses.
Let's say that they want to attack us, so do it in a specific country.
So what they use is they make use of VPN so that their IP address is not directly visible.
Now one thing I quickly shared let's see, this is just for an example.
Let's say that someone wants to attack a server which is residing in the US.
So what I do is I select a VPN which belongs to it.
And in my country, let's say China.
So a US and China, they are generally not a good friends.
So now if you use a VPN server of China and even if the U.S. government might want to get information,
Chinese government might not cooperate.
So this is what generally attackers do.
A lot of times they generally choose the VPN server of a country which is an enemy of their target that
they are trying to exploit in any way.
So this is just the high level overview and some of the things that I wanted to share.
This is more appropriate for the certifications related to security anyways.
So when.
Comes to the VPN using corporate network.
So this is like a good VPN.
So how exactly it is used is let's say that you have two instance in a private subnet and this has a
private IP.
So private IP cannot be communicated directly via the Internet.
So it is nonprofitable IP.
So what you do is you put a VPN server in the public subnet inside the BBC and then you route your traffic
from your computer to the VPN and from the VPN to other private instances.
So now if you want to connect to private incents, your traffic will be routed from VPN to the private
insurers.
And this is how the weapon is typically used in the established environment.
So this is the high level overview about the virtual private network.
I hope this video has been informative and I look forward to seeing the next video.
