OK.
So now that we understand that Toure is basically a network of devices connected to each other that
we can use to improve our privacy and anonymity.
The question is how can we connect to this network and use it.
Well the answer is actually very simple.
You can configure your computer regardless of what operating system it uses to rout all traffic through
the Tor network.
And that way hopefully everything will flow through the network protecting your privacy and anonymity.
Sadly though this is not always the case as you probably have a lot of programs that I don't even know
of that could leak information about you potentially revealing your location your IP and more information.
Not only that but you could be running an unpublished version of Windows or Linux or even OSX.
Also your browser could leak information about you even if you think you properly configured it to use
Tor.
Also a lot of us use browser plugins and browser extensions which also could potentially leak information.
And finally we have the exit node problem and the previous lecture I already mentioned that when you
connect to Tor all the data and green in here is sent encrypted and at any time none of the nodes know
what web you want to go to.
They only know the address of the next node so they can forward the data to the next node.
But as I mentioned the Red Arrow in here means the data leaving in here will leave unencrypted unless
he's TTP as is used.
So you'll have to go and manually install TTP as everywhere to force data to be sent over hash TTP as
also we have this node right here.
This is known as the exit node.
And the problem here is anybody can actually configure a computer to work as a node in the Tor network.
And if your computer is an exit node you will be able to see this data leave an unencrypted.
So you have to trust this person.
If you're really using the detour network as they can potentially see everything you do now.
Like I said in the previous lecture if the target's Web site uses hash TTP s or if you're using a plugin
that will force hash TTP connections then this will be okay because the data will be encrypted by SSL
cause he's TTP as encrypts the hash TTP data.
So you'll be fine.
But this is again another step that you have to take and another plug in that you have to install on
your browser in order to make sure that your data is fully encrypted along the way.
And even if someone is able to see this data such as the person running the exit node here or if there
is someone in here intercepting the connection even if they capture the data they will not be able to
read it because it will be encrypted.
So like I said there is a lot of steps to do if you want to configure your computer to use data or network.
And even if you do all of that you could miss a tiny or a small detail that could potentially leak information
and reveal your identity therefore a better solution is to either use the Tor Browser and we'll talk
about that in the next section.
This is a web browser designed by the same people that run the Tor network throughout all the data through
the terror network by default.
It also has a lot of other features to prevent leaking your information and ensuring the data that you
send is always encrypted.
This is the simplest and a good solution a better solution would be to use tells which is a Linux distro
designed for anonymity and privacy.
And the best solution would be use in Cuba so as with Unix Gateway which is an amazing operating system
that is very very secure and also can be configured to use Tor by default improving your security and
anonymity and privacy.
Now we will go over all of this in the next lectures starting with the simplest and easiest and will
and with the more complex but the best approach.
