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.
