1 00:00:00,850 --> 00:00:06,910 Now that we have tails installed configured with persistence and we learned the basics on how to use 2 00:00:06,910 --> 00:00:08,600 it and interact with it. 3 00:00:08,770 --> 00:00:15,580 In this lecture I want to talk about detail browser that comes with tails and highlights a major restriction 4 00:00:15,850 --> 00:00:23,640 that tails enforces over the Tor web browser so go into the applications. 5 00:00:23,750 --> 00:00:30,440 You can see we have in our favorites detailed browser as you know we've actually covered this browser 6 00:00:30,440 --> 00:00:30,940 before. 7 00:00:30,950 --> 00:00:36,980 And we spoke about how it works and we learned how to install it on different operating systems and 8 00:00:36,980 --> 00:00:43,030 how to properly configure it for optimum security and anonymity. 9 00:00:43,140 --> 00:00:47,800 So what we have here is an identical version to the browser that I showed you before. 10 00:00:47,910 --> 00:00:53,460 You can go to check the Tor Project dot org to make sure that everything is connected but we already 11 00:00:53,460 --> 00:00:59,940 know that everything is working because as I mentioned before all connections sent from Tales from the 12 00:00:59,940 --> 00:01:06,870 whole operating system go through the Tor network and we can confirm this from this onion but if you 13 00:01:06,870 --> 00:01:15,360 really just want to double check you can just go to check the Tor Project dot org and as you can see 14 00:01:15,360 --> 00:01:22,110 it's telling us that everything is working everything's configured properly and we are using the network. 15 00:01:22,200 --> 00:01:28,890 Now as I showed you before you can go to the onion icon in here to request a new identity change security 16 00:01:28,890 --> 00:01:31,200 settings or check for updates. 17 00:01:31,200 --> 00:01:38,680 You can check your tor circuit from here and you can also modify the options from here. 18 00:01:38,700 --> 00:01:44,760 Now like I said I spent multiple lectures explaining what the circuit is what do we mean by a new identity 19 00:01:44,760 --> 00:01:50,980 and a new circuit how to modify the security options for optimum security and anonymity. 20 00:01:51,240 --> 00:01:52,890 So I'm not going to talk about that. 21 00:01:52,890 --> 00:01:58,410 Now you can go ahead and do everything that I showed you previously because the steps to do with here 22 00:01:58,620 --> 00:02:05,210 are identical to the steps you'd follow with any Tor Browser regardless of what operating system it's 23 00:02:05,220 --> 00:02:07,130 installed on. 24 00:02:07,140 --> 00:02:13,590 So I'm just gonna go and change my security settings and crack that to the safest. 25 00:02:13,590 --> 00:02:16,120 And we are good to go. 26 00:02:16,140 --> 00:02:20,880 I'm also going to keep the screen at this size because as I mentioned before you don't want to use the 27 00:02:20,880 --> 00:02:26,160 screen in full screen because that'll give information about your monitor. 28 00:02:26,160 --> 00:02:31,850 Also keeping it at the default site is always a good idea because that makes you less unique. 29 00:02:31,890 --> 00:02:40,130 And like I said Tor and tales work best by making it hard to distinguish the users that use these services. 30 00:02:40,140 --> 00:02:47,100 So when we keep the window at the default size it's harder to distinguish between me and other users. 31 00:02:47,190 --> 00:02:54,180 What I want to cover though in this lecture is an extra feature that tells implements or an extra restriction 32 00:02:54,390 --> 00:03:03,000 that tells applies to the TOR browser to improve the security of the whole browser so that it's more 33 00:03:03,000 --> 00:03:10,380 difficult to exploit and use to gain access to our system tools implement kernel level restrictions 34 00:03:10,650 --> 00:03:19,590 over the Tor browser so that it cannot access any folder any location within the file system except 35 00:03:19,650 --> 00:03:21,920 for one folder. 36 00:03:21,990 --> 00:03:28,440 Therefore if we wanted to download something from the browser or upload something we can only do that 37 00:03:28,440 --> 00:03:32,200 from one folder in our file system. 38 00:03:32,310 --> 00:03:39,780 So if we look at the places here you'll see we have a folder called Tor Browser and we have a folder 39 00:03:39,780 --> 00:03:45,810 called Tor Browser persistent because I enabled persistence on my installation. 40 00:03:45,810 --> 00:03:53,760 You will only see this if you enable persistence and as the names suggest the browser folder is non 41 00:03:53,760 --> 00:03:54,580 persistent. 42 00:03:54,600 --> 00:04:00,870 So anything you place in this folder will be deleted once you shut down or restart tales. 43 00:04:00,960 --> 00:04:03,630 The persistent folder is persistent. 44 00:04:03,630 --> 00:04:11,260 So if you store anything in that folder it will not be deleted when you restart or shut down tells now 45 00:04:11,260 --> 00:04:18,870 these two folders or directories are the only folders that detour browser has access to. 46 00:04:18,940 --> 00:04:24,880 So if for example you wanted to save this image so you're going to go right click and save image as 47 00:04:25,060 --> 00:04:26,830 I'm just giving this as an example. 48 00:04:26,890 --> 00:04:30,060 But this applies for anything that you want to save. 49 00:04:30,130 --> 00:04:35,430 You'll see you are automatically an amnesia which is the name of our user tor browser. 50 00:04:35,440 --> 00:04:41,590 So this is the path that we are in and if we wanted to change this path to save this somewhere else. 51 00:04:41,590 --> 00:04:48,740 For example if you click on desktop you'll see we're get an error message saying permission denied you'll 52 00:04:48,740 --> 00:04:49,910 get this error message. 53 00:04:49,910 --> 00:04:57,200 If you click on any other directory in your computer except the Tor Browser directories the third browser 54 00:04:57,230 --> 00:05:00,080 normal and deter browser persistent. 55 00:05:00,110 --> 00:05:06,920 So let's stop this for example Ed browser in here and it's just going to be called Tor on PDG. 56 00:05:07,280 --> 00:05:08,990 I'm going to save it. 57 00:05:08,990 --> 00:05:16,270 And now if I go to places Tor Browser you'll see we have the image here. 58 00:05:16,420 --> 00:05:18,910 So it's just like any other directory. 59 00:05:18,940 --> 00:05:24,600 The only thing is this is the only directory that is visible to the TOR browser. 60 00:05:24,670 --> 00:05:31,270 So the same thing applies if you wanted to upload a file and send it anywhere you want to be able to 61 00:05:31,300 --> 00:05:37,410 upload any files unless they are stored in tor browser or indeed your browser persistent. 62 00:05:37,420 --> 00:05:43,390 So if you had something on desktop or in music or in the documents you'll have to first copy it to one 63 00:05:43,390 --> 00:05:51,010 of these directories either too tor browser or Tor Browser persistent and then upload it from there. 64 00:05:51,010 --> 00:05:57,100 So if I just go to a tiny upload dot com this is a file sharing service. 65 00:05:57,130 --> 00:05:59,700 It's by no means anonymous or private. 66 00:05:59,830 --> 00:06:07,240 I'm just using it as an example to show you how the browser only have access to specific directories. 67 00:06:07,240 --> 00:06:13,400 So if I click on browse the select the file that I want to upload again you can see by default in detail 68 00:06:13,410 --> 00:06:17,490 the browser directory which I can upload files from with no problems. 69 00:06:17,830 --> 00:06:24,610 But if I try to go to my documents again I'll get the same error downloads or any other directory. 70 00:06:24,760 --> 00:06:26,830 I'll always be getting this error. 71 00:06:26,950 --> 00:06:33,250 Therefore if you want to upload something you'll have to copy it paste it in your browser or your tour 72 00:06:33,250 --> 00:06:34,480 browser persistent. 73 00:06:34,480 --> 00:06:41,590 If you have one if you enabled persistence and then from here you can just selected open it and it will 74 00:06:41,590 --> 00:06:44,960 upload just like any other operating system. 75 00:06:45,100 --> 00:06:49,960 Now like I said this is not a private or an anonymous way of uploading files. 76 00:06:49,960 --> 00:06:56,570 I will show you a better way later on in the course so that's it for this lecture. 77 00:06:56,590 --> 00:07:00,990 We've already used the term browser and we are already a little bit familiar with it. 78 00:07:01,000 --> 00:07:08,200 I just wanted to highlight the restriction that tells enforces on the Tor Browser and in the next lecture 79 00:07:08,260 --> 00:07:13,300 I'm going to introduce you to the insecure browser that comes with tales.
