1 00:00:00,800 --> 00:00:05,670 You know to learn and remember the cons and the cause is good to practically try things out. 2 00:00:05,880 --> 00:00:11,940 So as we go through the course I'd like to spend time exploring the configurations that I talk about 3 00:00:12,270 --> 00:00:15,370 and the operating systems and the settings. 4 00:00:15,450 --> 00:00:20,820 And when you see something that I demonstrate anything that will that might apply to your situation 5 00:00:21,240 --> 00:00:26,610 then you want to try those things out because obviously trying things out is the best way to actually 6 00:00:26,610 --> 00:00:27,380 learn. 7 00:00:27,480 --> 00:00:34,110 And one way to do this without MS configuring your own machine is to use a virtual environment to play 8 00:00:34,110 --> 00:00:36,100 around in and to learn. 9 00:00:36,240 --> 00:00:43,930 And these are also called platform the translation software or hypervisor is which is really the business 10 00:00:43,940 --> 00:00:51,400 software that emulates a whole physical computer or machine and often provides multiple virtual machines 11 00:00:51,400 --> 00:00:54,410 and one physical platform. 12 00:00:54,420 --> 00:01:03,450 So for example and if you see here we have the hardware which would be your laptop your physical device 13 00:01:03,930 --> 00:01:06,940 and then you've got the operating system here. 14 00:01:07,050 --> 00:01:13,910 So that would be this operating system that you can see is Windows in this case Windows 7. 15 00:01:14,190 --> 00:01:21,650 And then you have the hypervisor the software that allows you to create virtualization and this case 16 00:01:21,650 --> 00:01:29,340 I've got some virtualization software and this hypervisor is virtual box. 17 00:01:29,430 --> 00:01:36,480 So this is a virtual box here the hypervisor and it's running a particular operating system but it could 18 00:01:36,480 --> 00:01:45,540 run many operating systems and you can see that here it is running a Windows 7 within the Windows 7. 19 00:01:45,930 --> 00:01:51,810 So here we have a nice virtual environment within an environment. 20 00:01:51,810 --> 00:01:59,560 This is considered to be the host and this is considered to be the guest operating system. 21 00:01:59,580 --> 00:02:04,440 Now if we go back to the diagram again and this is from Wikipedia. 22 00:02:04,630 --> 00:02:09,910 So yeah you can see this is a hosted It's known as a type 2 because you can have different types of 23 00:02:09,910 --> 00:02:15,610 virtualization but we're talking about testing here setting up testing environments so that you can 24 00:02:15,610 --> 00:02:16,420 try things out. 25 00:02:16,420 --> 00:02:21,740 This is the sort of environment that we'd want to use so you can ignore this type of environment. 26 00:02:21,760 --> 00:02:29,470 Now the time warm so this will be a machine your native laptop and whichever operating system you use 27 00:02:29,950 --> 00:02:36,220 and you can use different operating systems if you are on Mac or if you're on Windows if you're on Linux 28 00:02:36,760 --> 00:02:44,290 you can run high for viruses on all of those different operating systems and then put on a different 29 00:02:44,290 --> 00:02:45,720 operating system. 30 00:02:45,730 --> 00:02:54,540 Now there are lots of different virtualization software I mean the the big two really are VM Ware and 31 00:02:54,610 --> 00:03:06,430 virtual box and I have as you've seen Virtual Box here and this next to it and this is what VM Ware 32 00:03:06,460 --> 00:03:08,590 looks like very very similar. 33 00:03:08,770 --> 00:03:11,320 And this is desktop virtualization. 34 00:03:11,320 --> 00:03:19,020 This is actually being where workstation 12 player but there are others I mean this things like they 35 00:03:19,030 --> 00:03:27,580 grown Hyper-V the PC but for the purposes of setting up a test environment so you can play around with 36 00:03:27,580 --> 00:03:33,330 configurations and settings then really I recommend VM where Virtual Box. 37 00:03:33,400 --> 00:03:37,300 Now there are two purposes for using virtual environments. 38 00:03:37,300 --> 00:03:44,140 Now right now we're talking about for testing things out like to roam We're also going to talk about 39 00:03:44,140 --> 00:03:50,130 how virtualization can be used as a method to give you security and privacy. 40 00:03:50,170 --> 00:03:52,710 So we've got a section on that as well. 41 00:03:52,720 --> 00:03:59,050 Now if you want to explore around the topic and the different types of virtualization software you can 42 00:03:59,050 --> 00:04:04,860 go to this page on Wikipedia and you can see all the different types of virtualization software I mean 43 00:04:04,900 --> 00:04:10,690 as you know you can see there's quite a lot of them as quite a useful site if you want to learn a little 44 00:04:10,690 --> 00:04:11,530 bit more. 45 00:04:11,860 --> 00:04:16,870 And the and the heart of the Lincoln Wikipedia is pretty good. 46 00:04:16,870 --> 00:04:22,930 Pretty sure just tells you about virtualization if you're interested in knowing a little bit more. 47 00:04:22,930 --> 00:04:29,940 The obvious question is how do you actually get these operating systems into these virtual machines. 48 00:04:30,250 --> 00:04:37,810 Well one way is exactly the same as you would if you had your own laptop your own hardware you would 49 00:04:37,810 --> 00:04:44,710 get a CD you put it in and you would install it just the same as you would with physical hardware. 50 00:04:45,010 --> 00:04:51,700 Now you therefore can of course go by the operating system that you're looking for so if you want Windows 51 00:04:52,120 --> 00:04:59,080 10 or whatever it is you go by it you get sent to CD and you put it in and you install that and I'll 52 00:04:59,080 --> 00:05:02,680 show you the details of how that's done but we're just going through at the moment the different ways 53 00:05:02,680 --> 00:05:04,850 of getting operating systems on. 54 00:05:05,020 --> 00:05:07,600 So that's a physical CD. 55 00:05:07,600 --> 00:05:13,860 Another option is you use a virtual CD and I'll show you an example of that. 56 00:05:13,880 --> 00:05:17,680 So say you want the Debian operating system to be installed. 57 00:05:17,830 --> 00:05:18,480 You need to. 58 00:05:18,490 --> 00:05:19,600 Which is free. 59 00:05:19,630 --> 00:05:28,540 You need to find the equivalent of the CD and digital versions of CDs are created and one format that 60 00:05:28,540 --> 00:05:30,180 can be used is ISO. 61 00:05:30,180 --> 00:05:37,930 So if you see here this is Debian by clicking here is going to enable me to download the latest Debian 62 00:05:38,050 --> 00:05:40,290 ISO which is effectively a disk. 63 00:05:40,300 --> 00:05:44,740 I would then start my hypervisor with this ISO in the drive. 64 00:05:44,740 --> 00:05:47,250 It would boot and then I would start to install it. 65 00:05:47,260 --> 00:05:51,260 So that's one option that's ISO's and disks to get them on. 66 00:05:51,550 --> 00:06:00,580 Now the other option is you can you can get very conveniently pre-made virtual disks where someone has 67 00:06:00,910 --> 00:06:05,850 installed it for you and they package it up into a virtual disk. 68 00:06:06,220 --> 00:06:09,450 If you're interested then for example Windows machines. 69 00:06:09,580 --> 00:06:13,750 Now this is a great link for Windows operating systems. 70 00:06:13,900 --> 00:06:23,030 So if you go here you can download virtual machines here with XP Vista Windows 7 Windows 10. 71 00:06:23,050 --> 00:06:26,950 These are test versions but that's what we use this this is for testing. 72 00:06:27,250 --> 00:06:28,690 You can select here. 73 00:06:28,690 --> 00:06:36,820 Select your platform so you may be using virtual baulks download and then you can have a virtual image 74 00:06:37,030 --> 00:06:43,150 and that will end up looking something like what's the VM version. 75 00:06:43,150 --> 00:06:48,330 This is a virtual box version you'll end up getting something like this in large file. 76 00:06:48,330 --> 00:06:54,220 You can see this is 4 gig which is the virtual disk and you can just straight away run that and that's 77 00:06:54,220 --> 00:06:56,050 exactly what I've done here. 78 00:06:56,060 --> 00:07:02,440 I've downloaded it and I've run it and that's that's the file that I'm running. 79 00:07:02,440 --> 00:07:07,360 That is Windows 7 running in Virtual Box from that file. 80 00:07:10,570 --> 00:07:11,350 Very quick. 81 00:07:11,410 --> 00:07:13,200 Very nice very easy. 82 00:07:13,210 --> 00:07:15,890 Just download it and it's ready to use. 83 00:07:15,990 --> 00:07:21,250 So that's the Windows environment and you can also get the Linux and all the other operating systems 84 00:07:21,250 --> 00:07:31,290 to Linux and Linux type operating systems you can go to this Web site iceboxes dot org This is for them 85 00:07:31,290 --> 00:07:40,830 way images a virtual box can go here same Web site different you R-AL And if you scroll down you can 86 00:07:40,830 --> 00:07:46,540 see all the Linux top operating systems arsh Linux. 87 00:07:46,690 --> 00:07:49,470 Here's an example click here. 88 00:07:53,170 --> 00:08:01,180 Scroll down and there is the options the virtual box option the V.M. where option the 32 and 64 bit 89 00:08:01,180 --> 00:08:02,100 version. 90 00:08:02,270 --> 00:08:07,150 And if you're not sure the difference between 32 and 64 bit version then that's something for you to 91 00:08:07,150 --> 00:08:07,490 do. 92 00:08:07,490 --> 00:08:13,720 Google it find out what operating system you have and then download the corresponding operating system 93 00:08:13,960 --> 00:08:19,330 version and you can see here the user name and password for any operating system the download is obviously 94 00:08:19,330 --> 00:08:20,230 important. 95 00:08:20,230 --> 00:08:23,570 Now don't worry if you don't understand about all these different operators and we're going to go through 96 00:08:23,590 --> 00:08:28,180 different operating systems which are secure which are not secure. 97 00:08:28,300 --> 00:08:34,210 Privacy issues to deal with them this is just to give you an understanding of setting up test environments 98 00:08:34,210 --> 00:08:39,900 and how you can use virtual machines to follow me as we go through this course. 99 00:08:39,910 --> 00:08:48,260 Another link for V.M. Where is this and you can find walk call virtual appliances. 100 00:08:48,260 --> 00:08:53,890 So again it is Benway way images you download these and that would be. 101 00:08:53,940 --> 00:09:01,210 Now this is some sort of a buntu appliance into a Linux based operating system and a couple other useful 102 00:09:01,210 --> 00:09:02,350 links. 103 00:09:02,590 --> 00:09:04,080 Virtual Machine. 104 00:09:04,180 --> 00:09:06,050 Or check that one out. 105 00:09:09,180 --> 00:09:14,250 And another useful long the jukeboxes dot org. 106 00:09:14,670 --> 00:09:18,690 And you can find some some things on here. 107 00:09:18,720 --> 00:09:26,250 Now of course remember well remember I haven't said that these shouldn't be trusted environments someone 108 00:09:26,250 --> 00:09:31,240 else has built the virtual environment so you can't trust them that we're not using it for trust here 109 00:09:31,260 --> 00:09:37,890 we're using them for testing and for playing around with things when something isn't within a virtual 110 00:09:37,890 --> 00:09:38,810 machine. 111 00:09:38,880 --> 00:09:44,410 It is pretty isolated from your main machine and we are so much more about that later on. 112 00:09:44,550 --> 00:09:51,810 You should see these downloaded test images as purely that for testing and not for real environments 113 00:09:51,810 --> 00:09:57,540 going forward when we get to that section we're going to potentially set up real virtual environments 114 00:09:57,540 --> 00:10:00,290 that you can use for security and privacy.
