WEBVTT 00:00.500 --> 00:04.760 Now we have a number of options when it comes to installing tails. 00:04.910 --> 00:08.720 The easiest is to install it as a virtual machine. 00:09.230 --> 00:15.170 With this option, you're going to, first of all, install a virtualization software such as VirtualBox 00:15.170 --> 00:22.130 or VMware inside your current operating system, whether it's Linux, Windows or OS X, and then you 00:22.130 --> 00:27.410 will install tails as a virtual machine using this virtualization software. 00:28.300 --> 00:30.130 So you won't have to restart. 00:30.130 --> 00:35.620 You won't have to reboot in order to start Thales, you'll be able to start it within your operating 00:35.620 --> 00:42.550 system, within Windows or Linux or OS X, and you won't need a USB stick or a DVD to start it. 00:43.390 --> 00:50.680 The problems with this is Thales will lose most of its benefits when it's installed like this, because, 00:50.680 --> 00:54.560 like I said, Thales is designed to be a live operating system. 00:54.580 --> 00:59.620 One of the main advantages of it is the fact that it's amnesic. 00:59.620 --> 01:05.110 So when you use it on a computer and turn off that computer, it leaves no traces. 01:05.110 --> 01:12.280 So even if that computer is inspected, they won't even know that this computer was used to run Thales. 01:12.610 --> 01:18.790 When Thales is installed as a virtual machine, it's going to share the resources with your host operating 01:18.790 --> 01:21.120 system with Windows, Linux or OS X. 01:21.130 --> 01:24.650 This means that it will leave traces of it being used. 01:24.670 --> 01:29.560 You also want to be able to have a USB stick that you can use on any computer. 01:29.560 --> 01:34.770 You'll only be able to use Thales within that computer that you install the virtual machine on. 01:34.780 --> 01:42.220 And because Thales is installed on Windows the next OS X, like we said before, these operating systems 01:42.220 --> 01:43.940 collect data about you. 01:43.960 --> 01:48.050 Not only that, they also have a number of programs that collect data about you. 01:48.070 --> 01:52.750 All of these programs access the Internet directly, not through the Tor network. 01:52.750 --> 01:59.110 And all of these programs and operating systems could be vulnerable to code execution or buffer overflows, 01:59.110 --> 02:01.780 which can be used to hack into your computer. 02:01.780 --> 02:09.760 And again, from there, the anonymize you therefore install entails as a virtual machine is not great 02:09.760 --> 02:15.040 because it will basically lose a lot of its advantages and a lot of its great features. 02:16.080 --> 02:24.330 The second option, which is better, is to install tails on a DVD and then use that DVD to boot Thales. 02:24.330 --> 02:29.860 So you can use that DVD on any computer regardless of what operating system it runs. 02:29.880 --> 02:36.000 All you have to do is just put the DVD in, restart the computer boot from the DVD, and then you'll 02:36.000 --> 02:37.470 be able to use Thales. 02:37.500 --> 02:41.190 Now with this tells will come with all of its great features. 02:41.190 --> 02:47.730 So it will be live, it will leave no traces and it will be running natively so it won't be sharing 02:47.730 --> 02:48.600 resources. 02:48.600 --> 02:54.780 Therefore you won't really need to worry about clicks or about other programs, collecting data or any 02:54.780 --> 03:00.720 of the other stuff that we have to take into consideration when we're running the Tor browser or when 03:00.720 --> 03:02.970 we're running Thales as a virtual machine. 03:03.960 --> 03:07.660 The only disadvantage to this method is the size of the DVD. 03:07.680 --> 03:13.200 It's a little bit big and the installation of tails will not be persistent. 03:13.230 --> 03:19.410 What I mean by that is if you store any files while you're using tails, you will lose them once you 03:19.410 --> 03:21.930 turn off the computer or restarted. 03:22.860 --> 03:27.910 The third option, which is the best in my opinion, is using a USB stick. 03:27.930 --> 03:30.880 So this comes with all of the benefits of the DVD. 03:30.900 --> 03:36.930 We're going to install tails on a USB stick and then all you'll have to do is connect that USB stick 03:36.930 --> 03:40.830 to any computer regardless of what operating system it runs. 03:40.860 --> 03:44.830 Restart that computer and you'll be able to boot into tails. 03:44.850 --> 03:45.300 Tails. 03:45.300 --> 03:48.170 We run in its live mode again. 03:48.180 --> 03:49.920 They won't use any resources. 03:49.920 --> 03:54.120 If you turn off that computer, there will be no traces on that computer. 03:54.840 --> 04:00.240 And we can also configure this installation to be persistent. 04:00.360 --> 04:07.980 This means that we can actually use part of the USB storage as storage for tails, so you can actually 04:07.980 --> 04:11.850 save files within your current installation within the USB stick. 04:11.850 --> 04:15.210 And when you turn off the computer, there'll still be no traces. 04:15.210 --> 04:21.570 But even if you go and connect this USB stick to a completely new computer, you will still have your 04:21.570 --> 04:25.110 files, you'll be able to boot tails again and use it normally. 04:25.110 --> 04:31.470 And that way you'll have an operating system installed on a really small storage device that you can 04:31.470 --> 04:36.450 boot on any computer in the world, regardless of what operating system it runs. 04:37.050 --> 04:42.990 And you'll be able to store files and once you turn off that operating system wants to turn off that 04:42.990 --> 04:46.770 computer, there will be no traces on the computer. 04:46.770 --> 04:52.200 So even if it gets inspected, there will be no traces of it, even running tails. 04:52.740 --> 04:58.800 So you probably guessed by now installing tails on a USB stick is the best option. 04:58.800 --> 05:02.280 And in the next lecture, I'm going to show you how to do that.
