So if 2 00:00:06.400 --> 00:00:09.600 you're wondering how do I get started with using Cali? I 3 00:00:09.600 --> 00:00:12.400 want to get it downloaded get it working. But I want to do it securely 4 00:00:12.400 --> 00:00:15.600 great questions. So those are some of the objectives that 5 00:00:15.600 --> 00:00:18.500 we're going to be touching on here soon how to safely download 6 00:00:18.500 --> 00:00:21.300 Cali and validate that it is. In 7 00:00:21.300 --> 00:00:24.600 fact secure some basic, you know use of a hypervisor 8 00:00:24.600 --> 00:00:27.200 and how to find one and what that is and knowing that 9 00:00:27.200 --> 00:00:30.600 a high level the differences between a full installation 10 00:00:30.600 --> 00:00:33.500 versus a live boot of Cali. So 11 00:00:33.500 --> 00:00:36.000 let's go ahead and jump into where we can get Cali from 12 00:00:36.600 --> 00:00:39.600 So using your web browser, you can navigate to 13 00:00:39.600 --> 00:00:42.300 cali.org/downloads. Now, there's 14 00:00:42.300 --> 00:00:46.100 a lot of different distributions, but we're going to focus on the 64-bit or 15 00:00:45.100 --> 00:00:48.400 32 bit variants of that. We did 16 00:00:48.400 --> 00:00:51.800 a quick click over here to download the flavor of choice and you'll 17 00:00:51.800 --> 00:00:54.100 notice that's happening that there's a check sum over here 18 00:00:54.100 --> 00:00:57.400 to the right. So keep that in mind we'll touch on that here in 19 00:00:57.400 --> 00:01:00.100 a moment and I'll show you how that checks some can be 20 00:01:00.100 --> 00:01:03.500 valuable and ensuring that your tools are secure. So 21 00:01:03.500 --> 00:01:07.100 let's go ahead and talk at a high level about hypervisor 22 00:01:06.100 --> 00:01:09.200 and what that is and you know how that's gonna help 23 00:01:09.200 --> 00:01:12.400 us to run Cali. So I did a quick search for 24 00:01:12.400 --> 00:01:16.000 one of my favorite hypervisors VMware Workstation 25 00:01:15.300 --> 00:01:18.100 player. So you can click on the 26 00:01:18.100 --> 00:01:21.200 downloads link over here and this will bring you 27 00:01:21.200 --> 00:01:25.100 to a page that looks similar to this at the time VMware 15 28 00:01:24.100 --> 00:01:27.800 workstation player was the current version. I went 29 00:01:27.800 --> 00:01:29.700 ahead and downloaded that for Windows now. 30 00:01:30.800 --> 00:01:33.300 You can use a different hypervisor to run 31 00:01:33.300 --> 00:01:36.300 this system. Essentially what this is doing is you 32 00:01:36.300 --> 00:01:39.300 have at the base your current operating system 33 00:01:39.300 --> 00:01:42.400 and this hypervisor is going to allow you 34 00:01:42.400 --> 00:01:45.600 to run what's called a guest or a 35 00:01:45.600 --> 00:01:48.600 guest operating system on top of that. So this will be Cali or 36 00:01:48.600 --> 00:01:51.600 any other thing you want to run. It's kind of like conception. 37 00:01:51.600 --> 00:01:54.600 It's a Dream Within A Dream. This is just an operating system 38 00:01:54.600 --> 00:01:57.500 within an operating system. You don't have to dual boot or 39 00:01:57.500 --> 00:02:01.400 do anything of that nature. You can just run it with your current hardware and 40 00:02:01.400 --> 00:02:04.800 resources makes it a little bit more convenient. So remember 41 00:02:04.800 --> 00:02:07.100 we talked about that checksum and what we were going to 42 00:02:07.100 --> 00:02:09.600 do with it. Let's touch on that at a high level as well. 43 00:02:10.300 --> 00:02:13.500 So a check sum is a way that we can validate the 44 00:02:13.500 --> 00:02:16.400 Integrity of a file. So in this case, we looked 45 00:02:16.400 --> 00:02:19.200 at this shot 256 check some right 46 00:02:19.200 --> 00:02:22.100 here. And those are what are over here to the right? So if you 47 00:02:22.100 --> 00:02:25.700 take this file do a check some using shot 256 48 00:02:25.700 --> 00:02:28.600 those numbers should match. So I used a 49 00:02:28.600 --> 00:02:31.900 tool that's online. It's called online md5.com was 50 00:02:31.900 --> 00:02:34.200 the site and you get a window that looks like this 51 00:02:34.200 --> 00:02:37.600 on the main page. I simply selected my downloaded version 52 00:02:37.600 --> 00:02:40.800 of Cali and selected the shot 256 check 53 00:02:40.800 --> 00:02:43.300 some type so it RAM and it provided 54 00:02:43.300 --> 00:02:46.200 me with this output. So what I did is I took the 55 00:02:46.200 --> 00:02:49.000 output and I compared it with the number that I 56 00:02:49.300 --> 00:02:52.500 had here and lo and behold we had a match. So what 57 00:02:52.500 --> 00:02:55.000 that tells me is that my tool should not have been 58 00:02:55.500 --> 00:02:58.100 altered and it should be in a safe State. You always want to 59 00:02:58.100 --> 00:03:01.800 check your tools and that just ensures that you don't get any infections or 60 00:03:01.800 --> 00:03:04.600 bad guys on your systems. So speaking of 61 00:03:04.600 --> 00:03:07.300 check sums and checking those. Let's do a quick check on learning. 62 00:03:08.300 --> 00:03:11.600 A tool that allows you to run a virtual machine is known 63 00:03:11.600 --> 00:03:15.600 as so we use this word a couple times Hardware 64 00:03:14.600 --> 00:03:17.500 definitely not so Hardware allows 65 00:03:17.500 --> 00:03:20.800 you to run tools without Hardware you really can't but in 66 00:03:20.800 --> 00:03:23.900 this case we're talking about the specific tool not Hardware. We 67 00:03:23.900 --> 00:03:26.700 didn't mention hyper terminals or using a 68 00:03:26.700 --> 00:03:29.400 hyper terminal that's typically used for configuring devices 69 00:03:29.400 --> 00:03:33.000 and things of that nature not in this case. Is it 70 00:03:32.200 --> 00:03:35.900 allowing us to run virtual machines? So the likely 71 00:03:35.900 --> 00:03:38.600 Choice here is a hypervisor. Remember a hypervisor 72 00:03:38.600 --> 00:03:41.900 allows us to run an operating system within an 73 00:03:41.900 --> 00:03:44.100 operating system. So let's go ahead and prepare for 74 00:03:44.100 --> 00:03:47.200 takeoff. You should go ahead and install your hypervisor of 75 00:03:47.200 --> 00:03:50.700 choice in this case. You're going to be looking at VMware 76 00:03:50.700 --> 00:03:54.500 Player and how we set Cali up from here. So once 77 00:03:53.500 --> 00:03:56.500 you get VMware Player installed or 78 00:03:56.500 --> 00:03:59.500 you're high provider of choice in my instance, I've 79 00:03:59.500 --> 00:04:02.300 already got several machines here, but you're going to go ahead 80 00:04:02.300 --> 00:04:06.300 and create a new virtual machine using the iso 81 00:04:05.300 --> 00:04:07.800 that you've downloaded. So 82 00:04:08.200 --> 00:04:11.400 Once you create a new virtual machine, it's going to give you this option 83 00:04:11.400 --> 00:04:14.500 and ask you to point to the file. So what you'll 84 00:04:14.500 --> 00:04:17.200 do is I downloaded my copy of Cali to a thumb 85 00:04:17.200 --> 00:04:20.600 drive selected it and Bam. There 86 00:04:20.600 --> 00:04:23.800 we go. It gives me this. I this new Option here. Now, 87 00:04:23.800 --> 00:04:26.200 you may note that the ram is a little bit lower on 88 00:04:26.200 --> 00:04:29.700 your machine. If you want to make an adjustment and change a 89 00:04:29.700 --> 00:04:32.100 few things with how resources are going 90 00:04:32.100 --> 00:04:35.400 to be allocated to this virtual machine, then you can edit those 91 00:04:35.400 --> 00:04:38.500 settings here when you click edit settings. You've got 92 00:04:38.500 --> 00:04:42.600 a couple options under Hardware at least in the VMware Player. 93 00:04:43.700 --> 00:04:45.700 hypervisor and from there 94 00:04:46.700 --> 00:04:48.100 I went ahead and selected memory. 95 00:04:49.500 --> 00:04:52.600 Bumped up the volume a little bit on that and now I've got two gigs 96 00:04:52.600 --> 00:04:55.200 to use. So when you're ready to get started you can go ahead and 97 00:04:55.200 --> 00:04:58.600 click the play button here in this case and you should 98 00:04:58.600 --> 00:05:00.700 get something that looks like this now. 99 00:05:02.400 --> 00:05:05.500 In this instance, we're going to be using live Boot and talking 100 00:05:05.500 --> 00:05:08.500 about that at a high level live. Boot essentially allows me 101 00:05:08.500 --> 00:05:11.500 to to not have to install Cali and it 102 00:05:11.500 --> 00:05:14.200 essentially just starts running allows me 103 00:05:14.200 --> 00:05:17.200 to jump right in and start working with some commands and some 104 00:05:17.200 --> 00:05:20.300 tools and doing some things but it's not persistent meaning if 105 00:05:20.300 --> 00:05:23.600 I reboot the system lose the system have to 106 00:05:23.600 --> 00:05:26.200 power it down. For some reason. I lose all my work 107 00:05:26.200 --> 00:05:29.600 and information but for the sake of the lessons we'll be doing live 108 00:05:29.600 --> 00:05:32.400 boot is going to be the quickest and easiest way to get started if you 109 00:05:32.400 --> 00:05:35.800 want to do a full install which is going to have persistence. It'll 110 00:05:35.800 --> 00:05:38.600 maintain information between reboots. It'll allow 111 00:05:38.600 --> 00:05:41.000 you to do some customization things of that 112 00:05:41.300 --> 00:05:44.400 nature by all means go ahead and do a graphic install and work 113 00:05:44.400 --> 00:05:47.800 with it from there. But once you live food into the traveling environment, 114 00:05:47.800 --> 00:05:50.400 you'll be ready to go and just have a desktop 115 00:05:50.400 --> 00:05:53.700 and and you can run in gun from there and then continue lessons and 116 00:05:53.700 --> 00:05:54.900 follow along with us there. 117 00:05:55.700 --> 00:05:58.300 So with those things in mind, let's do a 118 00:05:58.300 --> 00:06:01.300 quick check on learning now. We just talked about this. So keep that 119 00:06:01.300 --> 00:06:04.500 in mind. What is the primary difference between lifeboot and 120 00:06:04.500 --> 00:06:07.400 a full installation based on the options here? Well, we didn't 121 00:06:07.400 --> 00:06:10.800 talk about this but live boot is definitely not 122 00:06:10.800 --> 00:06:13.200 faster with the boot time. So, you know that is 123 00:06:13.200 --> 00:06:16.200 not a benefit of live. Boot. There's not a greater amount of 124 00:06:16.200 --> 00:06:19.100 tools or less amount of tools available based on one or the 125 00:06:19.100 --> 00:06:22.300 other you can add tools to the installation if you do a 126 00:06:22.300 --> 00:06:25.500 full install, but if you do that in my boot and then reboot you 127 00:06:25.500 --> 00:06:28.400 lose that and that comes to our answer here 128 00:06:28.400 --> 00:06:31.200 that there's no persistence between reboots with lab 129 00:06:31.200 --> 00:06:34.400 boots. So that's a very very major difference between a 130 00:06:34.400 --> 00:06:37.300 full installation in lifeboot. Now. I want to point out some 131 00:06:37.300 --> 00:06:40.200 additional resources that you can use for those of 132 00:06:40.200 --> 00:06:44.300 you that have access to the Lambs and things of that nature. I used 133 00:06:43.300 --> 00:06:47.200 the host data and Tegrity baselining lab 134 00:06:47.200 --> 00:06:50.100 and they have a copy of Cali Linux under the 135 00:06:50.100 --> 00:06:54.000 machines that you can use if you're not looking to download a 136 00:06:53.800 --> 00:06:55.000 hypervisor and 137 00:06:55.600 --> 00:06:58.300 Do an installation on your system and you would just rather Jump 138 00:06:58.300 --> 00:07:01.500 Right In and be able to work with some commands and start navigating 139 00:07:01.500 --> 00:07:04.700 the environment. This is a good lab and a virtual 140 00:07:04.700 --> 00:07:07.500 machine to use do keep in mind as we discussed previously. 141 00:07:07.500 --> 00:07:10.400 You may see some differences in some areas of this 142 00:07:10.400 --> 00:07:13.300 version versus the version. You may see me 143 00:07:13.300 --> 00:07:16.800 using in our navigation videos and things of that nature the command 144 00:07:16.800 --> 00:07:19.500 should still be the same and again the team 145 00:07:19.500 --> 00:07:22.500 is always updating tools updating what they use so you 146 00:07:22.500 --> 00:07:25.700 may see some differences, but don't fret the underlying commands 147 00:07:25.700 --> 00:07:27.200 that we'll use are going to remain the same. 148 00:07:28.200 --> 00:07:31.500 Now in summary, we went over Cali and a 149 00:07:31.500 --> 00:07:34.200 hypervisor and gave you some tips and tricks on how 150 00:07:34.200 --> 00:07:37.200 to ensure that those things are secure and safe when 151 00:07:37.200 --> 00:07:40.700 you're using them. We did some high level differences between lifeboot and 152 00:07:40.700 --> 00:07:43.700 a full installation and I gave you a few additional resources 153 00:07:43.700 --> 00:07:46.400 that you could use instead of having to install everything 154 00:07:46.400 --> 00:07:48.800 and just jump right in and start working some commands. 155 00:07:49.400 --> 00:07:52.300 So I thank you for your time today and I look forward to working with 156 00:07:52.300 --> 00:07:53.000 you again soon.
