1
00:00:00,690 --> 00:00:05,120
Now we have a number of options when it comes to installing tails.
2
00:00:05,130 --> 00:00:10,440
The easiest is to install it as a virtual machine with this option.
3
00:00:10,470 --> 00:00:16,920
You're going to first of all install a virtualization software such as virtual box or VM where inside
4
00:00:16,920 --> 00:00:23,760
your current operating system whether it's Linux Windows or OS X and then you'll install tales as a
5
00:00:23,760 --> 00:00:25,020
virtual machine.
6
00:00:25,020 --> 00:00:32,030
Using this virtualization software so you won't have to restart you won't have to reboot in order to
7
00:00:32,030 --> 00:00:32,870
start tales.
8
00:00:32,930 --> 00:00:39,650
You'll be able to started within your operating system within Windows or Linux or OS X and you won't
9
00:00:39,650 --> 00:00:48,030
need the USB stick or a DVD to started the problems with this is tails will lose most of its benefits
10
00:00:48,210 --> 00:00:50,280
when it's installed like this.
11
00:00:50,280 --> 00:00:57,600
Because like I said Thales is designed to be alive operating system one of the main advantages of it
12
00:00:57,660 --> 00:00:59,710
is the fact that it's amnesiac.
13
00:00:59,730 --> 00:01:05,250
So when you use it on a computer and turn off that computer it leaves no traces.
14
00:01:05,250 --> 00:01:12,090
So even if that computer is inspected they won't even know that this computer was used to run tails
15
00:01:12,840 --> 00:01:15,260
when tails is installed as a virtual machine.
16
00:01:15,600 --> 00:01:21,270
It's going to share the resources with your host operating system with Windows Linux or OS X.
17
00:01:21,360 --> 00:01:24,930
This means that it will leave traces of it being used.
18
00:01:24,930 --> 00:01:29,620
You also want to be able to have a USB stick that you can use on any computer.
19
00:01:29,640 --> 00:01:34,800
You'll only be able to use tools within that computer that you installed the virtual machine on.
20
00:01:34,950 --> 00:01:42,240
And because Thales is installed on Windows the next or OS X like we said before these operating systems
21
00:01:42,240 --> 00:01:44,010
collect data about you.
22
00:01:44,100 --> 00:01:48,240
Not only that they also have a number of programs that collect data about you.
23
00:01:48,240 --> 00:01:54,510
All of these programs access the Internet directly not through the Tor network and all of these programs
24
00:01:54,510 --> 00:02:00,180
and operating systems could be vulnerable to code execution or buffer overflows which can be used to
25
00:02:00,180 --> 00:02:01,710
hack into your computer.
26
00:02:01,920 --> 00:02:10,410
And again from there the anonymous you therefore install entails as a virtual machine is not great because
27
00:02:10,410 --> 00:02:17,560
it will basically lose a lot of its advantages and a lot of its great features the second option which
28
00:02:17,560 --> 00:02:23,950
is better is to install tables on a DVD and then use that DVD to boot.
29
00:02:23,970 --> 00:02:30,030
Tails so you can use the DVD on any computer regardless of what operating system it runs.
30
00:02:30,040 --> 00:02:36,130
All you have to do is just put the DVD and restart the computer boot from the DVD and then you'll be
31
00:02:36,130 --> 00:02:37,670
able to use tails.
32
00:02:37,690 --> 00:02:42,380
Now with this tells will come with all of its great features so it'll be life.
33
00:02:42,400 --> 00:02:48,640
It'll leave no traces and it'll be running natively so it won't be sharing resources.
34
00:02:48,760 --> 00:02:54,790
Therefore you won't really need to worry about leaks or about other programs collecting data or any
35
00:02:54,790 --> 00:03:00,730
of the other stuff that we have to take into consideration when we're running the tour browser or when
36
00:03:00,730 --> 00:03:02,830
we're running tails as a virtual machine.
37
00:03:04,000 --> 00:03:10,900
The only disadvantage to this method is the size of the DVD it's a little bit big and the installation
38
00:03:10,930 --> 00:03:13,410
of tails will not be persistent.
39
00:03:13,420 --> 00:03:18,840
What I mean by that is if you store any files while you're using tails you will lose them.
40
00:03:18,910 --> 00:03:26,670
Once you turn off the computer or restarted the third option which is the best in my opinion is using
41
00:03:26,700 --> 00:03:28,120
a USB stick.
42
00:03:28,140 --> 00:03:30,980
So this comes with all of the benefits of the DVD.
43
00:03:31,050 --> 00:03:36,870
We're going to install tails on a USB stick and then all you'll have to do is connect that USB stick
44
00:03:37,050 --> 00:03:41,030
to any computer regardless of what operating system it runs.
45
00:03:41,040 --> 00:03:44,880
Restart that computer and you'll be able to boot into tails.
46
00:03:44,940 --> 00:03:47,910
Tails will run in its live mode again.
47
00:03:48,120 --> 00:03:51,640
It won't use any resources if you turn off that computer.
48
00:03:51,720 --> 00:04:00,600
There will be no traces on that computer and we can also configure this installation to be persistent.
49
00:04:00,600 --> 00:04:07,980
This means that we can actually use part of the US b storage as storage for tails so you can actually
50
00:04:07,980 --> 00:04:13,590
save files within your current installation within the USB stick and when you turn off the computer
51
00:04:13,650 --> 00:04:15,280
there still be no traces.
52
00:04:15,420 --> 00:04:21,540
But even if you go and connect this USB stick to a completely new computer you will still have your
53
00:04:21,540 --> 00:04:22,150
files.
54
00:04:22,230 --> 00:04:28,140
You'll be able to boot tails again and use it normally and that way you'll have an operating system
55
00:04:28,350 --> 00:04:34,470
installed on a really small storage device that you can put on any computer in the world regardless
56
00:04:34,470 --> 00:04:36,880
of what operating system it runs.
57
00:04:37,140 --> 00:04:42,990
And you'll be able to store files and once you turn off that operating system wants to turn off that
58
00:04:42,990 --> 00:04:44,100
computer.
59
00:04:44,100 --> 00:04:46,830
There will be no traces on the computer.
60
00:04:46,890 --> 00:04:54,180
So even if it gets inspected there will be no traces of it even running tails so you probably guessed
61
00:04:54,180 --> 00:04:58,820
by now installing tails on a USB stick is the best option.
62
00:04:58,980 --> 00:05:02,040
And in the next lecture I'm gonna show you how to do that.
