1 1 00:00:00,570 --> 00:00:03,090 Internet of Things Vulnerabilities. 2 2 00:00:03,090 --> 00:00:05,130 In this lesson, we're going to start talking 3 3 00:00:05,130 --> 00:00:08,550 about IoT or the internet of things. 4 4 00:00:08,550 --> 00:00:10,260 Now, when I talk about internet of things, 5 5 00:00:10,260 --> 00:00:11,730 you may have heard this term before, 6 6 00:00:11,730 --> 00:00:14,130 and you really should if you've talked about A+, 7 7 00:00:14,130 --> 00:00:15,600 or Net+, or Security+, 8 8 00:00:15,600 --> 00:00:18,480 because these are all things that connect to our network. 9 9 00:00:18,480 --> 00:00:21,210 It can be things like trains, planes, and automobiles. 10 10 00:00:21,210 --> 00:00:24,270 It can be shopping carts. It can be your smart TV. 11 11 00:00:24,270 --> 00:00:25,710 It can be your cell phone. 12 12 00:00:25,710 --> 00:00:27,900 Pretty much anything that can connect to the internet 13 13 00:00:27,900 --> 00:00:30,120 could be considered an internet of things. 14 14 00:00:30,120 --> 00:00:32,460 For instance, there's some refrigerators out there right now 15 15 00:00:32,460 --> 00:00:34,650 that have the ability of connecting to the internet 16 16 00:00:34,650 --> 00:00:37,290 and using things like Alexa to be able to add things 17 17 00:00:37,290 --> 00:00:39,360 or take things away from your shopping list. 18 18 00:00:39,360 --> 00:00:41,820 All of that is part of the internet of things. 19 19 00:00:41,820 --> 00:00:44,880 So when we define the internet of things or IoT, 20 20 00:00:44,880 --> 00:00:47,010 we're really just talking about a group of objects 21 21 00:00:47,010 --> 00:00:48,810 and they can be electronic or not, 22 22 00:00:48,810 --> 00:00:51,360 and they all have to be connected to the wider internet 23 23 00:00:51,360 --> 00:00:53,820 by using embedded electronic components. 24 24 00:00:53,820 --> 00:00:56,430 That is what we define the internet of things. 25 25 00:00:56,430 --> 00:00:58,830 So if you think about your home, if you have a smart home, 26 26 00:00:58,830 --> 00:01:00,630 you might have a smart door lock on the front door 27 27 00:01:00,630 --> 00:01:01,800 that you use to get in. 28 28 00:01:01,800 --> 00:01:03,840 You have a camera that's sitting there to see people 29 29 00:01:03,840 --> 00:01:05,220 as they come up to your doorbell. 30 30 00:01:05,220 --> 00:01:06,510 And if they press on your doorbell, 31 31 00:01:06,510 --> 00:01:07,920 that can actually ring on your cell phone 32 32 00:01:07,920 --> 00:01:08,940 so you can know who's at the door 33 33 00:01:08,940 --> 00:01:10,860 before you get up from your couch. 34 34 00:01:10,860 --> 00:01:13,050 You might have a smart air conditioner that can keep track 35 35 00:01:13,050 --> 00:01:14,490 of what the temperature's in the room, 36 36 00:01:14,490 --> 00:01:16,380 and you can set it, and you can change it 37 37 00:01:16,380 --> 00:01:18,960 from anywhere in the world because it's internet connected. 38 38 00:01:18,960 --> 00:01:20,550 You might have a lighting system where you can control 39 39 00:01:20,550 --> 00:01:22,680 if it's going to be white or red or blue lights 40 40 00:01:22,680 --> 00:01:24,480 because they're connected to the internet too. 41 41 00:01:24,480 --> 00:01:26,640 And you could talk to that through your smartphone. 42 42 00:01:26,640 --> 00:01:29,340 You may have energy management or appliance control. 43 43 00:01:29,340 --> 00:01:30,330 You may have a smart device 44 44 00:01:30,330 --> 00:01:32,670 like a smart TV or a smart speaker. 45 45 00:01:32,670 --> 00:01:34,320 All of these things are different things 46 46 00:01:34,320 --> 00:01:36,150 that we can connect inside of our house, 47 47 00:01:36,150 --> 00:01:38,670 and they all give us a lot of great capability. 48 48 00:01:38,670 --> 00:01:40,020 But the biggest problem 49 49 00:01:40,020 --> 00:01:42,420 with these things is they're not always secure. 50 50 00:01:42,420 --> 00:01:45,270 And security is most often an afterthought to convenience 51 51 00:01:45,270 --> 00:01:47,610 when we start talking about smart devices. 52 52 00:01:47,610 --> 00:01:49,710 Now, most of our smart devices are going to use 53 53 00:01:49,710 --> 00:01:51,780 an embedded version of Linux or Android 54 54 00:01:51,780 --> 00:01:53,400 as their operating system. 55 55 00:01:53,400 --> 00:01:55,230 And so because they have Linux or Android 56 56 00:01:55,230 --> 00:01:58,230 as their operating system, they are vulnerable to attack. 57 57 00:01:58,230 --> 00:01:59,970 If there's a Linux vulnerability out there 58 58 00:01:59,970 --> 00:02:02,670 and you're using a Linux version on that smart device 59 59 00:02:02,670 --> 00:02:03,840 and that vulnerability matches, 60 60 00:02:03,840 --> 00:02:06,270 it can actually attack your smart speaker, for instance. 61 61 00:02:06,270 --> 00:02:08,190 And so these are things you have to think about 62 62 00:02:08,190 --> 00:02:09,960 as you start looking at your network, 63 63 00:02:09,960 --> 00:02:11,520 because if they're connected to your network, 64 64 00:02:11,520 --> 00:02:13,230 'cause you have a smart TV in the conference room, 65 65 00:02:13,230 --> 00:02:14,490 that could be an attack vector 66 66 00:02:14,490 --> 00:02:16,080 for somebody to get into your network. 67 67 00:02:16,080 --> 00:02:17,910 And that is one of the most common places I see people 68 68 00:02:17,910 --> 00:02:19,320 getting into a network through 69 69 00:02:19,320 --> 00:02:21,570 it's things like smart devices that are now connected 70 70 00:02:21,570 --> 00:02:22,800 to the corporate network. 71 71 00:02:22,800 --> 00:02:24,600 So you want to make sure they're properly installed, 72 72 00:02:24,600 --> 00:02:26,310 secured, and segmented 73 73 00:02:26,310 --> 00:02:28,080 when you put them into your corporate network 74 74 00:02:28,080 --> 00:02:30,270 if you're going to put 'em in your corporate network. 75 75 00:02:30,270 --> 00:02:33,210 Now these smart devices must be secured and updated 76 76 00:02:33,210 --> 00:02:35,190 when there's new vulnerabilities that are found. 77 77 00:02:35,190 --> 00:02:37,590 As I said, they're just running Linux or Android. 78 78 00:02:37,590 --> 00:02:39,120 And what happens is a lot of times, 79 79 00:02:39,120 --> 00:02:42,330 people will never update the software on these devices. 80 80 00:02:42,330 --> 00:02:44,100 So you might be running a version of Linux 81 81 00:02:44,100 --> 00:02:45,540 that's five years old 82 82 00:02:45,540 --> 00:02:48,330 because it was small and easy to put on a device. 83 83 00:02:48,330 --> 00:02:49,170 But you've never updated, 84 84 00:02:49,170 --> 00:02:51,570 so now it's got this huge vulnerability. 85 85 00:02:51,570 --> 00:02:55,380 So when you think about IoT, the idea of IoT and security, 86 86 00:02:55,380 --> 00:02:57,090 they really don't go together very well 87 87 00:02:57,090 --> 00:02:59,700 because most IoT manufacturers are not thinking 88 88 00:02:59,700 --> 00:03:01,650 about security when they build these devices. 89 89 00:03:01,650 --> 00:03:04,530 People buy smart speakers and lights and smart devices 90 90 00:03:04,530 --> 00:03:06,420 because they want convenience, 91 91 00:03:06,420 --> 00:03:08,700 and most people aren't thinking about security. 92 92 00:03:08,700 --> 00:03:10,110 So if you're going to install these things 93 93 00:03:10,110 --> 00:03:11,460 in your corporate network, 94 94 00:03:11,460 --> 00:03:14,340 you really have to think about this with a security lens. 95 95 00:03:14,340 --> 00:03:15,780 And one of the best things you can do 96 96 00:03:15,780 --> 00:03:18,480 is segment these devices often to their own network. 97 97 00:03:18,480 --> 00:03:20,850 So they're not talking to the rest of the corporate network. 98 98 00:03:20,850 --> 00:03:22,950 Don't allow them to be a device that people can use 99 99 00:03:22,950 --> 00:03:24,300 to be able to pivot into your network 100 100 00:03:24,300 --> 00:03:25,700 and get your corporate data.
