WEBVTT 00:00.800 --> 00:05.670 You know to learn and remember the cons and the cause is good to practically try things out. 00:05.880 --> 00:11.940 So as we go through the course I'd like to spend time exploring the configurations that I talk about 00:12.270 --> 00:15.370 and the operating systems and the settings. 00:15.450 --> 00:20.820 And when you see something that I demonstrate anything that will that might apply to your situation 00:21.240 --> 00:26.610 then you want to try those things out because obviously trying things out is the best way to actually 00:26.610 --> 00:27.380 learn. 00:27.480 --> 00:34.110 And one way to do this without MS configuring your own machine is to use a virtual environment to play 00:34.110 --> 00:36.100 around in and to learn. 00:36.240 --> 00:43.930 And these are also called platform the translation software or hypervisor is which is really the business 00:43.940 --> 00:51.400 software that emulates a whole physical computer or machine and often provides multiple virtual machines 00:51.400 --> 00:54.410 and one physical platform. 00:54.420 --> 01:03.450 So for example and if you see here we have the hardware which would be your laptop your physical device 01:03.930 --> 01:06.940 and then you've got the operating system here. 01:07.050 --> 01:13.910 So that would be this operating system that you can see is Windows in this case Windows 7. 01:14.190 --> 01:21.650 And then you have the hypervisor the software that allows you to create virtualization and this case 01:21.650 --> 01:29.340 I've got some virtualization software and this hypervisor is virtual box. 01:29.430 --> 01:36.480 So this is a virtual box here the hypervisor and it's running a particular operating system but it could 01:36.480 --> 01:45.540 run many operating systems and you can see that here it is running a Windows 7 within the Windows 7. 01:45.930 --> 01:51.810 So here we have a nice virtual environment within an environment. 01:51.810 --> 01:59.560 This is considered to be the host and this is considered to be the guest operating system. 01:59.580 --> 02:04.440 Now if we go back to the diagram again and this is from Wikipedia. 02:04.630 --> 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 02:09.910 --> 02:15.610 virtualization but we're talking about testing here setting up testing environments so that you can 02:15.610 --> 02:16.420 try things out. 02:16.420 --> 02:21.740 This is the sort of environment that we'd want to use so you can ignore this type of environment. 02:21.760 --> 02:29.470 Now the time warm so this will be a machine your native laptop and whichever operating system you use 02:29.950 --> 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 02:36.760 --> 02:44.290 you can run high for viruses on all of those different operating systems and then put on a different 02:44.290 --> 02:45.720 operating system. 02:45.730 --> 02:54.540 Now there are lots of different virtualization software I mean the the big two really are VM Ware and 02:54.610 --> 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 03:06.460 --> 03:08.590 looks like very very similar. 03:08.770 --> 03:11.320 And this is desktop virtualization. 03:11.320 --> 03:19.020 This is actually being where workstation 12 player but there are others I mean this things like they 03:19.030 --> 03:27.580 grown Hyper-V the PC but for the purposes of setting up a test environment so you can play around with 03:27.580 --> 03:33.330 configurations and settings then really I recommend VM where Virtual Box. 03:33.400 --> 03:37.300 Now there are two purposes for using virtual environments. 03:37.300 --> 03:44.140 Now right now we're talking about for testing things out like to roam We're also going to talk about 03:44.140 --> 03:50.130 how virtualization can be used as a method to give you security and privacy. 03:50.170 --> 03:52.710 So we've got a section on that as well. 03:52.720 --> 03:59.050 Now if you want to explore around the topic and the different types of virtualization software you can 03:59.050 --> 04:04.860 go to this page on Wikipedia and you can see all the different types of virtualization software I mean 04:04.900 --> 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 04:10.690 --> 04:11.530 bit more. 04:11.860 --> 04:16.870 And the and the heart of the Lincoln Wikipedia is pretty good. 04:16.870 --> 04:22.930 Pretty sure just tells you about virtualization if you're interested in knowing a little bit more. 04:22.930 --> 04:29.940 The obvious question is how do you actually get these operating systems into these virtual machines. 04:30.250 --> 04:37.810 Well one way is exactly the same as you would if you had your own laptop your own hardware you would 04:37.810 --> 04:44.710 get a CD you put it in and you would install it just the same as you would with physical hardware. 04:45.010 --> 04:51.700 Now you therefore can of course go by the operating system that you're looking for so if you want Windows 04:52.120 --> 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 04:59.080 --> 05:02.680 show you the details of how that's done but we're just going through at the moment the different ways 05:02.680 --> 05:04.850 of getting operating systems on. 05:05.020 --> 05:07.600 So that's a physical CD. 05:07.600 --> 05:13.860 Another option is you use a virtual CD and I'll show you an example of that. 05:13.880 --> 05:17.680 So say you want the Debian operating system to be installed. 05:17.830 --> 05:18.480 You need to. 05:18.490 --> 05:19.600 Which is free. 05:19.630 --> 05:28.540 You need to find the equivalent of the CD and digital versions of CDs are created and one format that 05:28.540 --> 05:30.180 can be used is ISO. 05:30.180 --> 05:37.930 So if you see here this is Debian by clicking here is going to enable me to download the latest Debian 05:38.050 --> 05:40.290 ISO which is effectively a disk. 05:40.300 --> 05:44.740 I would then start my hypervisor with this ISO in the drive. 05:44.740 --> 05:47.250 It would boot and then I would start to install it. 05:47.260 --> 05:51.260 So that's one option that's ISO's and disks to get them on. 05:51.550 --> 06:00.580 Now the other option is you can you can get very conveniently pre-made virtual disks where someone has 06:00.910 --> 06:05.850 installed it for you and they package it up into a virtual disk. 06:06.220 --> 06:09.450 If you're interested then for example Windows machines. 06:09.580 --> 06:13.750 Now this is a great link for Windows operating systems. 06:13.900 --> 06:23.030 So if you go here you can download virtual machines here with XP Vista Windows 7 Windows 10. 06:23.050 --> 06:26.950 These are test versions but that's what we use this this is for testing. 06:27.250 --> 06:28.690 You can select here. 06:28.690 --> 06:36.820 Select your platform so you may be using virtual baulks download and then you can have a virtual image 06:37.030 --> 06:43.150 and that will end up looking something like what's the VM version. 06:43.150 --> 06:48.330 This is a virtual box version you'll end up getting something like this in large file. 06:48.330 --> 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 06:54.220 --> 06:56.050 exactly what I've done here. 06:56.060 --> 07:02.440 I've downloaded it and I've run it and that's that's the file that I'm running. 07:02.440 --> 07:07.360 That is Windows 7 running in Virtual Box from that file. 07:10.570 --> 07:11.350 Very quick. 07:11.410 --> 07:13.200 Very nice very easy. 07:13.210 --> 07:15.890 Just download it and it's ready to use. 07:15.990 --> 07:21.250 So that's the Windows environment and you can also get the Linux and all the other operating systems 07:21.250 --> 07:31.290 to Linux and Linux type operating systems you can go to this Web site iceboxes dot org This is for them 07:31.290 --> 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 07:40.830 --> 07:46.540 see all the Linux top operating systems arsh Linux. 07:46.690 --> 07:49.470 Here's an example click here. 07:53.170 --> 08:01.180 Scroll down and there is the options the virtual box option the V.M. where option the 32 and 64 bit 08:01.180 --> 08:02.100 version. 08:02.270 --> 08:07.150 And if you're not sure the difference between 32 and 64 bit version then that's something for you to 08:07.150 --> 08:07.490 do. 08:07.490 --> 08:13.720 Google it find out what operating system you have and then download the corresponding operating system 08:13.960 --> 08:19.330 version and you can see here the user name and password for any operating system the download is obviously 08:19.330 --> 08:20.230 important. 08:20.230 --> 08:23.570 Now don't worry if you don't understand about all these different operators and we're going to go through 08:23.590 --> 08:28.180 different operating systems which are secure which are not secure. 08:28.300 --> 08:34.210 Privacy issues to deal with them this is just to give you an understanding of setting up test environments 08:34.210 --> 08:39.900 and how you can use virtual machines to follow me as we go through this course. 08:39.910 --> 08:48.260 Another link for V.M. Where is this and you can find walk call virtual appliances. 08:48.260 --> 08:53.890 So again it is Benway way images you download these and that would be. 08:53.940 --> 09:01.210 Now this is some sort of a buntu appliance into a Linux based operating system and a couple other useful 09:01.210 --> 09:02.350 links. 09:02.590 --> 09:04.080 Virtual Machine. 09:04.180 --> 09:06.050 Or check that one out. 09:09.180 --> 09:14.250 And another useful long the jukeboxes dot org. 09:14.670 --> 09:18.690 And you can find some some things on here. 09:18.720 --> 09:26.250 Now of course remember well remember I haven't said that these shouldn't be trusted environments someone 09:26.250 --> 09:31.240 else has built the virtual environment so you can't trust them that we're not using it for trust here 09:31.260 --> 09:37.890 we're using them for testing and for playing around with things when something isn't within a virtual 09:37.890 --> 09:38.810 machine. 09:38.880 --> 09:44.410 It is pretty isolated from your main machine and we are so much more about that later on. 09:44.550 --> 09:51.810 You should see these downloaded test images as purely that for testing and not for real environments 09:51.810 --> 09:57.540 going forward when we get to that section we're going to potentially set up real virtual environments 09:57.540 --> 10:00.290 that you can use for security and privacy.
