WEBVTT 00:01.040 --> 00:05.660 So it's just considered security features and security bugs of operating systems. 00:05.720 --> 00:11.960 But what affects the likelihood of there being threats to your operating system the most thus increasing 00:11.960 --> 00:14.370 your risk based on your operating system. 00:14.540 --> 00:21.680 Well that's the usage share of the operating system i.e. how popular is the operating system that you 00:21.680 --> 00:22.440 are using. 00:22.580 --> 00:26.630 So let's have a look at the statistics when it comes to usage share. 00:26.660 --> 00:33.740 Here we are looking at data from a site or a company called stat counter and look at this huge market 00:33.740 --> 00:37.000 share from Microsoft Windows operating system. 00:37.200 --> 00:45.800 81 percent of the total desktop operating system market is Windows followed by Mac OS at a relatively 00:45.800 --> 00:52.240 tiny 13 percent which actually is up from 8 percent in 2015. 00:52.250 --> 00:55.430 So it's up 5 percent since 2015. 00:55.430 --> 01:01.520 So Mac OSS is becoming more popular and taking over a little bit of the Windows market. 01:01.520 --> 01:09.590 Then look at Linux and chromis tiny tiny percentage of actual usage of the Windows operating systems 01:09.590 --> 01:16.940 we can see a further break down Windows 10 has the majority share around 46 percent which is not too 01:16.940 --> 01:18.000 much of a surprise. 01:18.020 --> 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 01:25.580 --> 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 01:31.730 --> 01:33.120 Windows 7. 01:33.140 --> 01:35.570 And amazingly people are still using XP. 01:35.570 --> 01:36.750 Can you believe it. 01:36.770 --> 01:38.000 I'm not surprised. 01:38.000 --> 01:39.320 Worth noting. 01:39.320 --> 01:45.090 Desktops and laptops are no longer the most used form of computer. 01:45.180 --> 01:48.500 Smartphones are at 51 percent usage. 01:48.500 --> 01:51.410 Desktops are up 44 percent usage. 01:51.410 --> 01:55.340 We will talk about smartphone statistics in a minute. 01:55.430 --> 02:01.730 Cyber criminals like any budding entrepreneur wants to get the best return on investment in time and 02:01.730 --> 02:02.780 effort. 02:02.910 --> 02:10.860 It makes much more sense to target the largest demographic of users which is Windows generally. 02:10.870 --> 02:14.400 Malware is written for a single type of operating system. 02:14.430 --> 02:20.320 So because Windows still has the greatest market share that's where they're going to aim. 02:20.360 --> 02:21.540 That's where the money is. 02:22.480 --> 02:31.070 Book Mac users need to be aware the walls are circling with increased popularity and increased number 02:31.150 --> 02:35.500 and severity when reality is criminals will start to focus on math. 02:35.680 --> 02:43.840 If we moved down here you can see another way of viewing the U.S. statistics and now including the mobiles. 02:43.990 --> 02:53.770 And look you can see Android is becoming extremely popular and mirroring its popularity is a massive 02:53.800 --> 02:56.800 increase in attacks against Android. 02:57.160 --> 03:04.450 If you buy an Android device you need to buy it from Google or a major manufacturer who provides timely 03:04.450 --> 03:06.540 updates to security books. 03:06.580 --> 03:13.150 There are currently millions of vulnerable Android phones out there that will never be patched because 03:13.360 --> 03:15.800 nobody's providing the patches for them. 03:15.970 --> 03:22.840 A vulnerability called stagefright means that a picture message can be sent to those phones to take 03:22.840 --> 03:23.670 control. 03:23.800 --> 03:26.370 And there's millions of Matlab hon. 03:26.380 --> 03:30.170 So what does this tell us all about the operating system that we should pick. 03:30.400 --> 03:42.250 Well Linux offers the most secure operating system plus it has a tiny usage share which means the real 03:42.250 --> 03:47.130 risk the threat landscape for Linux is tiny. 03:47.380 --> 03:53.770 On the downside it's difficult to get applications for it and don't support all the applications that 03:53.770 --> 03:54.520 you're going to need. 03:54.520 --> 04:00.280 So it's a it's a tradeoff there but you will get the most security from a Linux type environment. 04:00.520 --> 04:03.370 Not many people are attacking Linux. 04:03.790 --> 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 04:13.900 --> 04:16.050 it has reasonable security features. 04:16.120 --> 04:22.480 I would say Mac is probably a good balance for your average user that cares about security and also 04:22.480 --> 04:24.120 cares about usability. 04:24.190 --> 04:28.140 But you do also increase cost which is unfortunate. 04:28.420 --> 04:30.440 And then you have Windows. 04:30.700 --> 04:35.330 It is the highest market share is attacked the most. 04:35.520 --> 04:40.410 But this course is the solution to mitigate the risks. 04:40.420 --> 04:47.380 So although you may be running with an operating system that is attacked the most there are solutions 04:47.380 --> 04:51.380 to help you mitigate risk and this is what this course is going to do for you. 04:51.520 --> 04:56.830 And with some simple and easy steps you'll be able to reduce your risk massively so that they don't 04:56.830 --> 04:57.550 go after you. 04:57.550 --> 04:59.940 They go after the low hanging fruit.
