1 00:00:00,000 --> 00:00:04,000 Now we have a number of options when it comes to installing tails. 2 00:00:04,000 --> 00:00:08,000 The easiest is to install it as a virtual machine. 3 00:00:09,000 --> 00:00:15,000 With this option, you're going to, first of all, install a virtualization software such as VirtualBox 4 00:00:15,000 --> 00:00:22,000 or VMware inside your current operating system, whether it's Linux, Windows or OS X, and then you 5 00:00:22,000 --> 00:00:27,000 will install tails as a virtual machine using this virtualization software. 6 00:00:28,000 --> 00:00:30,000 So you won't have to restart. 7 00:00:30,000 --> 00:00:35,000 You won't have to reboot in order to start Thales, you'll be able to start it within your operating 8 00:00:35,000 --> 00:00:42,000 system, within Windows or Linux or OS X, and you won't need a USB stick or a DVD to start it. 9 00:00:43,000 --> 00:00:50,000 The problems with this is Thales will lose most of its benefits when it's installed like this, because, 10 00:00:50,000 --> 00:00:54,000 like I said, Thales is designed to be a live operating system. 11 00:00:54,000 --> 00:00:59,000 One of the main advantages of it is the fact that it's amnesic. 12 00:00:59,000 --> 00:01:05,000 So when you use it on a computer and turn off that computer, it leaves no traces. 13 00:01:05,000 --> 00:01:12,000 So even if that computer is inspected, they won't even know that this computer was used to run Thales. 14 00:01:12,000 --> 00:01:18,000 When Thales is installed as a virtual machine, it's going to share the resources with your host operating 15 00:01:18,000 --> 00:01:21,000 system with Windows, Linux or OS X. 16 00:01:21,000 --> 00:01:24,000 This means that it will leave traces of it being used. 17 00:01:24,000 --> 00:01:29,000 You also want to be able to have a USB stick that you can use on any computer. 18 00:01:29,000 --> 00:01:34,000 You'll only be able to use Thales within that computer that you install the virtual machine on. 19 00:01:34,000 --> 00:01:42,000 And because Thales is installed on Windows the next OS X, like we said before, these operating systems 20 00:01:42,000 --> 00:01:43,000 collect data about you. 21 00:01:43,000 --> 00:01:48,000 Not only that, they also have a number of programs that collect data about you. 22 00:01:48,000 --> 00:01:52,000 All of these programs access the Internet directly, not through the Tor network. 23 00:01:52,000 --> 00:01:59,000 And all of these programs and operating systems could be vulnerable to code execution or buffer overflows, 24 00:01:59,000 --> 00:02:01,000 which can be used to hack into your computer. 25 00:02:01,000 --> 00:02:09,000 And again, from there, the anonymize you therefore install entails as a virtual machine is not great 26 00:02:09,000 --> 00:02:15,000 because it will basically lose a lot of its advantages and a lot of its great features. 27 00:02:16,000 --> 00:02:24,000 The second option, which is better, is to install tails on a DVD and then use that DVD to boot Thales. 28 00:02:24,000 --> 00:02:29,000 So you can use that DVD on any computer regardless of what operating system it runs. 29 00:02:29,000 --> 00:02:36,000 All you have to do is just put the DVD in, restart the computer boot from the DVD, and then you'll 30 00:02:36,000 --> 00:02:37,000 be able to use Thales. 31 00:02:37,000 --> 00:02:41,000 Now with this tells will come with all of its great features. 32 00:02:41,000 --> 00:02:47,000 So it will be live, it will leave no traces and it will be running natively so it won't be sharing 33 00:02:47,000 --> 00:02:48,000 resources. 34 00:02:48,000 --> 00:02:54,000 Therefore you won't really need to worry about clicks or about other programs, collecting data or any 35 00:02:54,000 --> 00:03:00,000 of the other stuff that we have to take into consideration when we're running the Tor browser or when 36 00:03:00,000 --> 00:03:02,000 we're running Thales as a virtual machine. 37 00:03:03,000 --> 00:03:07,000 The only disadvantage to this method is the size of the DVD. 38 00:03:07,000 --> 00:03:13,000 It's a little bit big and the installation of tails will not be persistent. 39 00:03:13,000 --> 00:03:19,000 What I mean by that is if you store any files while you're using tails, you will lose them once you 40 00:03:19,000 --> 00:03:21,000 turn off the computer or restarted. 41 00:03:22,000 --> 00:03:27,000 The third option, which is the best in my opinion, is using a USB stick. 42 00:03:27,000 --> 00:03:30,000 So this comes with all of the benefits of the DVD. 43 00:03:30,000 --> 00:03:36,000 We're going to install tails on a USB stick and then all you'll have to do is connect that USB stick 44 00:03:36,000 --> 00:03:40,000 to any computer regardless of what operating system it runs. 45 00:03:40,000 --> 00:03:44,000 Restart that computer and you'll be able to boot into tails. 46 00:03:44,000 --> 00:03:45,000 Tails. 47 00:03:45,000 --> 00:03:48,000 We run in its live mode again. 48 00:03:48,000 --> 00:03:49,000 They won't use any resources. 49 00:03:49,000 --> 00:03:54,000 If you turn off that computer, there will be no traces on that computer. 50 00:03:54,000 --> 00:04:00,000 And we can also configure this installation to be persistent. 51 00:04:00,000 --> 00:04:07,000 This means that we can actually use part of the USB storage as storage for tails, so you can actually 52 00:04:07,000 --> 00:04:11,000 save files within your current installation within the USB stick. 53 00:04:11,000 --> 00:04:15,000 And when you turn off the computer, there'll still be no traces. 54 00:04:15,000 --> 00:04:21,000 But even if you go and connect this USB stick to a completely new computer, you will still have your 55 00:04:21,000 --> 00:04:25,000 files, you'll be able to boot tails again and use it normally. 56 00:04:25,000 --> 00:04:31,000 And that way you'll have an operating system installed on a really small storage device that you can 57 00:04:31,000 --> 00:04:36,000 boot on any computer in the world, regardless of what operating system it runs. 58 00:04:37,000 --> 00:04:42,000 And you'll be able to store files and once you turn off that operating system wants to turn off that 59 00:04:42,000 --> 00:04:46,000 computer, there will be no traces on the computer. 60 00:04:46,000 --> 00:04:52,000 So even if it gets inspected, there will be no traces of it, even running tails. 61 00:04:52,000 --> 00:04:58,000 So you probably guessed by now installing tails on a USB stick is the best option. 62 00:04:58,000 --> 00:05:02,000 And in the next lecture, I'm going to show you how to do that.
