Everybody welcome to the next video.
So in this video going to be talking about V.P. ends.
So what is a VPN a VPN stands for virtual private network.
Now this type of network allows for secure data to be transmitted from one point to another.
So from for example your machine to a web server or from one office to another privately and safely
route your connection.
What happens is is you actually travel through another machine.
So you're using the connection off of another machine.
This in turn will hide the source IP address that you're originally coming from.
Now this is important because this allow.
This is what allows some attackers to kind of bypass firewalls and stop.
Now what we're going to go over here is why it's use which we explain a little bit already.
You can hide your actions from the original IP so your IP from your from your Internet service provider
or ISP has given you a IP address.
You have that it has on file for you.
Now what you're doing is you're using your going through another system so that IP is the one actually
making the calls that you're making.
That means the IP or the source IP that the Web services is not your original IP but it's the VPN IP.
Again this secures one connection or one office to another such as a remote office to HQ or remote office
to a remote office.
It's commonly used for for those type of things at the switch.
I'm sorry.
The router firewall level again this hides an attacker source.
Now depending on the VPN it is easy for the police or government agency to identify and grab the logs
to know what the original source was which is why most attackers will piggyback off of quite a few of
them.
Some in places that they don't that the U.S. does not have jurisdiction in this particular example.
Now this also can bypass IP block.
So if you're on your regular machine you do something stupid you get blocked or you're doing an engagement
and your password sprang out.
And then the company blocks your IP natural.
You're going to go out hop on a VPN and you can now continue your engagement without having your IP
blocked.
This is pretty common a lot of consulting companies will have their own IP or their own VPN that they
will just using consistently rotate IP addresses.
If one of their consultants gets blocks during an engagement.
