1 00:00:01,040 --> 00:00:05,660 So it's just considered security features and security bugs of operating systems. 2 00:00:05,720 --> 00:00:11,960 But what affects the likelihood of there being threats to your operating system the most thus increasing 3 00:00:11,960 --> 00:00:14,370 your risk based on your operating system. 4 00:00:14,540 --> 00:00:21,680 Well that's the usage share of the operating system i.e. how popular is the operating system that you 5 00:00:21,680 --> 00:00:22,440 are using. 6 00:00:22,580 --> 00:00:26,630 So let's have a look at the statistics when it comes to usage share. 7 00:00:26,660 --> 00:00:33,740 Here we are looking at data from a site or a company called stat counter and look at this huge market 8 00:00:33,740 --> 00:00:37,000 share from Microsoft Windows operating system. 9 00:00:37,200 --> 00:00:45,800 81 percent of the total desktop operating system market is Windows followed by Mac OS at a relatively 10 00:00:45,800 --> 00:00:52,240 tiny 13 percent which actually is up from 8 percent in 2015. 11 00:00:52,250 --> 00:00:55,430 So it's up 5 percent since 2015. 12 00:00:55,430 --> 00:01:01,520 So Mac OSS is becoming more popular and taking over a little bit of the Windows market. 13 00:01:01,520 --> 00:01:09,590 Then look at Linux and chromis tiny tiny percentage of actual usage of the Windows operating systems 14 00:01:09,590 --> 00:01:16,940 we can see a further break down Windows 10 has the majority share around 46 percent which is not too 15 00:01:16,940 --> 00:01:18,000 much of a surprise. 16 00:01:18,020 --> 00:01:25,580 But no Windows 7 is at a staggering 40 percent which is why I still cover the cost because so many people 17 00:01:25,580 --> 00:01:31,730 don't want to move to Windows 10 even though it was offered to them for free as a free upgrade from 18 00:01:31,730 --> 00:01:33,120 Windows 7. 19 00:01:33,140 --> 00:01:35,570 And amazingly people are still using XP. 20 00:01:35,570 --> 00:01:36,750 Can you believe it. 21 00:01:36,770 --> 00:01:38,000 I'm not surprised. 22 00:01:38,000 --> 00:01:39,320 Worth noting. 23 00:01:39,320 --> 00:01:45,090 Desktops and laptops are no longer the most used form of computer. 24 00:01:45,180 --> 00:01:48,500 Smartphones are at 51 percent usage. 25 00:01:48,500 --> 00:01:51,410 Desktops are up 44 percent usage. 26 00:01:51,410 --> 00:01:55,340 We will talk about smartphone statistics in a minute. 27 00:01:55,430 --> 00:02:01,730 Cyber criminals like any budding entrepreneur wants to get the best return on investment in time and 28 00:02:01,730 --> 00:02:02,780 effort. 29 00:02:02,910 --> 00:02:10,860 It makes much more sense to target the largest demographic of users which is Windows generally. 30 00:02:10,870 --> 00:02:14,400 Malware is written for a single type of operating system. 31 00:02:14,430 --> 00:02:20,320 So because Windows still has the greatest market share that's where they're going to aim. 32 00:02:20,360 --> 00:02:21,540 That's where the money is. 33 00:02:22,480 --> 00:02:31,070 Book Mac users need to be aware the walls are circling with increased popularity and increased number 34 00:02:31,150 --> 00:02:35,500 and severity when reality is criminals will start to focus on math. 35 00:02:35,680 --> 00:02:43,840 If we moved down here you can see another way of viewing the U.S. statistics and now including the mobiles. 36 00:02:43,990 --> 00:02:53,770 And look you can see Android is becoming extremely popular and mirroring its popularity is a massive 37 00:02:53,800 --> 00:02:56,800 increase in attacks against Android. 38 00:02:57,160 --> 00:03:04,450 If you buy an Android device you need to buy it from Google or a major manufacturer who provides timely 39 00:03:04,450 --> 00:03:06,540 updates to security books. 40 00:03:06,580 --> 00:03:13,150 There are currently millions of vulnerable Android phones out there that will never be patched because 41 00:03:13,360 --> 00:03:15,800 nobody's providing the patches for them. 42 00:03:15,970 --> 00:03:22,840 A vulnerability called stagefright means that a picture message can be sent to those phones to take 43 00:03:22,840 --> 00:03:23,670 control. 44 00:03:23,800 --> 00:03:26,370 And there's millions of Matlab hon. 45 00:03:26,380 --> 00:03:30,170 So what does this tell us all about the operating system that we should pick. 46 00:03:30,400 --> 00:03:42,250 Well Linux offers the most secure operating system plus it has a tiny usage share which means the real 47 00:03:42,250 --> 00:03:47,130 risk the threat landscape for Linux is tiny. 48 00:03:47,380 --> 00:03:53,770 On the downside it's difficult to get applications for it and don't support all the applications that 49 00:03:53,770 --> 00:03:54,520 you're going to need. 50 00:03:54,520 --> 00:04:00,280 So it's a it's a tradeoff there but you will get the most security from a Linux type environment. 51 00:04:00,520 --> 00:04:03,370 Not many people are attacking Linux. 52 00:04:03,790 --> 00:04:13,900 Then you have your Mac OS X which has got a nice balance it's not a well targeted operating system and 53 00:04:13,900 --> 00:04:16,050 it has reasonable security features. 54 00:04:16,120 --> 00:04:22,480 I would say Mac is probably a good balance for your average user that cares about security and also 55 00:04:22,480 --> 00:04:24,120 cares about usability. 56 00:04:24,190 --> 00:04:28,140 But you do also increase cost which is unfortunate. 57 00:04:28,420 --> 00:04:30,440 And then you have Windows. 58 00:04:30,700 --> 00:04:35,330 It is the highest market share is attacked the most. 59 00:04:35,520 --> 00:04:40,410 But this course is the solution to mitigate the risks. 60 00:04:40,420 --> 00:04:47,380 So although you may be running with an operating system that is attacked the most there are solutions 61 00:04:47,380 --> 00:04:51,380 to help you mitigate risk and this is what this course is going to do for you. 62 00:04:51,520 --> 00:04:56,830 And with some simple and easy steps you'll be able to reduce your risk massively so that they don't 63 00:04:56,830 --> 00:04:57,550 go after you. 64 00:04:57,550 --> 00:04:59,940 They go after the low hanging fruit.
