1
00:00:00,000 --> 00:00:08,000
Now that we have Thales installed on a USB stick, we can use this USB stick to boot into Thales from

2
00:00:08,000 --> 00:00:15,000
any computer, regardless of what operating system that computer runs, whether it runs Windows Linux

3
00:00:15,000 --> 00:00:18,000
or OSX, it doesn't really matter.

4
00:00:18,000 --> 00:00:25,000
All we'll have to do is connect the USB device that we installed Thales to, to the computer that we

5
00:00:25,000 --> 00:00:29,000
want to run Thales on, start the computer or restart it.

6
00:00:29,000 --> 00:00:37,000
If it's already running, then as it starts, before it even gets into the loading page of Windows or

7
00:00:37,000 --> 00:00:42,000
as soon as it starts, you want to enter the boot menu.

8
00:00:42,000 --> 00:00:49,000
Now this varies depending on the computer that you have, so you'll have to press a button or maybe

9
00:00:49,000 --> 00:00:53,000
a combination of buttons in order to enter the boot menu.

10
00:00:53,000 --> 00:00:57,000
And this will differ depending on your computer.

11
00:00:57,000 --> 00:01:04,000
So here I have a list of the most common brands and the corresponding keys that will allow you to enter

12
00:01:04,000 --> 00:01:05,000
the boot menu.

13
00:01:05,000 --> 00:01:11,000
For example, if you have an Acer, you should try to press escape F12 or F9.

14
00:01:11,000 --> 00:01:19,000
So what you do is you connect your USB device to the computer, you start the computer or restart it.

15
00:01:19,000 --> 00:01:27,000
If it's already running, then keep pressing the escape button multiple times until you see a boot menu

16
00:01:27,000 --> 00:01:29,000
like this one or similar to this one.

17
00:01:30,000 --> 00:01:36,000
If you don't see it, if you boot into the default operating system that your computer usually boots

18
00:01:36,000 --> 00:01:41,000
in, then you should restart and try the next option in the list.

19
00:01:42,000 --> 00:01:47,000
If you tried all of the options and it still doesn't work, then check out the links in the resources

20
00:01:47,000 --> 00:01:51,000
of this lecture on more info on how to boot into tails.

21
00:01:51,000 --> 00:01:57,000
And if you can't find any help, then ask us in the Q&A section and we will respond to you within 15

22
00:01:57,000 --> 00:01:58,000
hours.

23
00:01:58,000 --> 00:02:05,000
Once you enter the boot menu, you want to select the option that will allow you to boot from a USB

24
00:02:05,000 --> 00:02:07,000
or an external storage.

25
00:02:07,000 --> 00:02:11,000
Hit enter and you will see the tails boot menu.

26
00:02:11,000 --> 00:02:17,000
As you can see in here, you want to keep this at the first option and hit enter.

27
00:02:17,000 --> 00:02:22,000
This will start booting tails from the USB device that she connected.

28
00:02:22,000 --> 00:02:25,000
So give it some time to start the operating system for you.

29
00:02:26,000 --> 00:02:27,000
Perfect.

30
00:02:27,000 --> 00:02:30,000
So as you can see, we have the welcome window of tales.

31
00:02:30,000 --> 00:02:36,000
And if you want to start straight away, all you have to do is just click on Start Tales.

32
00:02:36,000 --> 00:02:42,000
But before doing that, let's take a quick look on the options that we can modify in here.

33
00:02:42,000 --> 00:02:48,000
So first of all, you can modify the language which is set to English United States by default, and

34
00:02:48,000 --> 00:02:50,000
I'm going to keep it that way.

35
00:02:50,000 --> 00:02:53,000
The keyboard is also set to English us.

36
00:02:53,000 --> 00:02:58,000
Now you might you might want to modify this if you have a different layout, but I think it's a good

37
00:02:58,000 --> 00:03:03,000
idea to keep it at the default settings because that will give even less info.

38
00:03:03,000 --> 00:03:09,000
Now I know I said that tales won't leave any traces, but I just like to keep things to the default.

39
00:03:09,000 --> 00:03:10,000
In here.

40
00:03:11,000 --> 00:03:13,000
Again, we have the calendar format.

41
00:03:13,000 --> 00:03:15,000
I'm going to keep that to the default.

42
00:03:15,000 --> 00:03:21,000
The persistent storage option in here allows you to configure a portion of your storage to be persistent.

43
00:03:21,000 --> 00:03:23,000
We will talk about that later.

44
00:03:23,000 --> 00:03:28,000
And at the bottom here, we have additional settings or advanced settings.

45
00:03:29,000 --> 00:03:33,000
So I'm going to click on the plus to show you the settings that you can set here.

46
00:03:33,000 --> 00:03:37,000
And the first thing that you can set is an administration password.

47
00:03:38,000 --> 00:03:42,000
So by default tells disables the admin account.

48
00:03:42,000 --> 00:03:44,000
So as you can see, it's set to off.

49
00:03:44,000 --> 00:03:49,000
So when you go and use the operating system, there will be no admin.

50
00:03:49,000 --> 00:03:56,000
The reason it's configured this way so that if someone manages to hack into your system, they won't

51
00:03:56,000 --> 00:04:02,000
have admin permissions, so they won't be able to change core functions or core settings within the

52
00:04:02,000 --> 00:04:03,000
operating system.

53
00:04:03,000 --> 00:04:08,000
And they also won't be able to install any applications.

54
00:04:08,000 --> 00:04:15,000
If for some reason you needed to modify something that requires admin settings or if you wanted to install

55
00:04:15,000 --> 00:04:19,000
programs on the system, then you can enable the admin account.

56
00:04:19,000 --> 00:04:26,000
From here, you can click on this and you set a password, you repeat the password and click on Add

57
00:04:26,000 --> 00:04:27,000
to add it.

58
00:04:27,000 --> 00:04:32,000
Keep in mind that this account will only be added for this current session.

59
00:04:32,000 --> 00:04:38,000
Once you restart the computer, the admin account will disappear along with all the modifications that

60
00:04:38,000 --> 00:04:40,000
you make to tales.

61
00:04:40,000 --> 00:04:47,000
Because like we said, Tales is a live amnesic operating system that completely wipes everything that

62
00:04:47,000 --> 00:04:50,000
you do every time you restart the computer.

63
00:04:50,000 --> 00:04:56,000
So when you create an admin account in here and log in, this admin account will disappear and will

64
00:04:56,000 --> 00:04:59,000
not even exist once you restart the computer.

65
00:04:59,000 --> 00:05:04,000
So if you want to use an admin account again the next time you use the system, you're going to have

66
00:05:04,000 --> 00:05:06,000
to come to this menu and create it.

67
00:05:07,000 --> 00:05:13,000
But for now I don't really want to do anything that requires admin privileges and I don't want to install

68
00:05:13,000 --> 00:05:14,000
any programs.

69
00:05:14,000 --> 00:05:17,000
So I'm going to click on back and I'm going to keep this to off.

70
00:05:18,000 --> 00:05:22,000
The next setting that you might want to modify is the Mac spoofing.

71
00:05:22,000 --> 00:05:26,000
And as you can see, this is set to on by default.

72
00:05:27,000 --> 00:05:36,000
Now, Mac address is a unique and permanent address that is assigned to every network device.

73
00:05:37,000 --> 00:05:42,000
It gets assigned to it at the time the device is manufactured and it never changes.

74
00:05:42,000 --> 00:05:49,000
So, for example, if I have an Ethernet card or a Wi-Fi card and unplug it from my computer and connect

75
00:05:49,000 --> 00:05:55,000
it to a completely different computer, that card will still have the same MAC address.

76
00:05:55,000 --> 00:05:59,000
Now, this MAC address is only visible within your network.

77
00:05:59,000 --> 00:06:02,000
It's not visible on the internet, as we know.

78
00:06:02,000 --> 00:06:06,000
Tails automatically routes all internet traffic through Tor.

79
00:06:06,000 --> 00:06:10,000
So we're not really concerned about stuff that happens on the internet.

80
00:06:10,000 --> 00:06:13,000
It should hide our identity automatically.

81
00:06:13,000 --> 00:06:19,000
But within the network, the Mac address is visible and the Mac address is unique and permanent, like

82
00:06:19,000 --> 00:06:24,000
I said, and therefore it can be used to identify you.

83
00:06:24,000 --> 00:06:32,000
So this option by default is set to on and I'm going to keep it to on so that tails will also change

84
00:06:32,000 --> 00:06:35,000
my Mac address every time I start it.

85
00:06:35,000 --> 00:06:40,000
Therefore my Mac address will be changed so I'll be hidden or anonymous within the network.

86
00:06:40,000 --> 00:06:47,000
And when I connect to the internet, all the traffic will automatically go through the Tor network and

87
00:06:47,000 --> 00:06:49,000
therefore it will improve my anonymity.

88
00:06:50,000 --> 00:06:58,000
The only time you might want to set this to off is if the network that you're connecting to uses a whitelist.

89
00:06:58,000 --> 00:07:06,000
So if it's only allows specific MAC addresses to connect to it, and if your Mac address is one of these

90
00:07:06,000 --> 00:07:11,000
whitelisted Mac addresses, that's the only time that you might want to set this to off.

91
00:07:11,000 --> 00:07:18,000
Otherwise it's better to keep it at on so your identity is hidden within your network.

92
00:07:19,000 --> 00:07:23,000
Offline mode can be used to disable networking on tales.

93
00:07:23,000 --> 00:07:28,000
So if you are going to use the operating system for any use that does not require the internet, then

94
00:07:28,000 --> 00:07:32,000
it might be a good idea to disable networking for increased security.

95
00:07:33,000 --> 00:07:36,000
The unsafe browser is set to enabled.

96
00:07:36,000 --> 00:07:39,000
This is a browser that is not connected to the TOR network.

97
00:07:39,000 --> 00:07:44,000
So as I said, Tales automatically connects to the TOR network and routes all traffic through the Tor

98
00:07:44,000 --> 00:07:45,000
network.

99
00:07:45,000 --> 00:07:50,000
The only exception is the unsafe browser, so you can have it enabled in here or disabled if you want

100
00:07:50,000 --> 00:07:51,000
to disable it.

101
00:07:51,000 --> 00:07:55,000
We're going to keep it at enabled and we're going to talk about it in the future.

102
00:07:55,000 --> 00:07:57,000
So I'm not going to spend too much time talking about it.

103
00:07:57,000 --> 00:08:02,000
And the network connection option in here is obsolete, so you can't really do much from it from here

104
00:08:02,000 --> 00:08:03,000
anymore.

105
00:08:03,000 --> 00:08:08,000
But we will be talking about your connection and how to use bridges and pluggable transports later on

106
00:08:08,000 --> 00:08:09,000
in the course.

107
00:08:09,000 --> 00:08:13,000
So now that I'm happy with the options, I'm going to click on Cancel and I'm going to click on Start

108
00:08:13,000 --> 00:08:16,000
Tales to start the operating system.

109
00:08:17,000 --> 00:08:22,000
And as you can see, we get the tails desktop, which is very simple and very easy to use.

110
00:08:22,000 --> 00:08:26,000
Don't worry about the fact that it looks pretty different than what you're used to.

111
00:08:26,000 --> 00:08:31,000
We will talk about it and I'm going to teach you how to use it step by step as we go through the course.

112
00:08:31,000 --> 00:08:38,000
But as you can see, as soon as the system started, we got this connection window that is asking us

113
00:08:38,000 --> 00:08:40,000
how do we want to connect to the Tor network?

114
00:08:40,000 --> 00:08:47,000
So the first option is to connect automatically and the second one is to hide to my local network that

115
00:08:47,000 --> 00:08:48,000
I'm connecting to Tor.

116
00:08:49,000 --> 00:08:53,000
So basically the first option will connect you directly to the Tor network.

117
00:08:53,000 --> 00:08:56,000
The second option will allow you to configure a bridge.

118
00:08:56,000 --> 00:09:02,000
You can also configure a bridge using the first option and then ticking the configure bridge option.

119
00:09:02,000 --> 00:09:09,000
If you click on next, you can either use a default bridge, ask to get a bridge by email, or enter

120
00:09:09,000 --> 00:09:12,000
a bridge that you already obtained manually, just as shown previously.

121
00:09:12,000 --> 00:09:14,000
So I'm not going to cover that.

122
00:09:14,000 --> 00:09:15,000
We learned how to do this previously.

123
00:09:16,000 --> 00:09:18,000
All you have to do is simply paste the bridge in here.

124
00:09:19,000 --> 00:09:25,000
So I'm going to go back and tick the box and simply connect automatically to the Tor network.

125
00:09:25,000 --> 00:09:28,000
Click on Connect and watch this icon.

126
00:09:28,000 --> 00:09:31,000
So right now we have an X beside the onion.

127
00:09:31,000 --> 00:09:35,000
But now that we are connected, the X has disappeared from this icon.

128
00:09:35,000 --> 00:09:42,000
And if we click it, we'll be able to see the onion circuit that is being used to route our traffic.

129
00:09:42,000 --> 00:09:48,000
So as mentioned, all traffic going out of this operating system is going to be routed through the Tor

130
00:09:48,000 --> 00:09:52,000
network, not only the traffic going from the Tor browser.

131
00:09:52,000 --> 00:09:58,000
Now you can also start the Tor browser by clicking on this button here, or you can start it from the

132
00:09:58,000 --> 00:09:59,000
applications menu.

133
00:09:59,000 --> 00:10:02,000
Like I said, don't worry about this at all.

134
00:10:02,000 --> 00:10:02,000
We will.

135
00:10:02,000 --> 00:10:07,000
We will talk about how to use this operating system step by step as we go through the course.
