1
00:00:00,330 --> 00:00:05,750
Let's quickly discuss mobile operating systems and security privacy and anonymity.

2
00:00:05,760 --> 00:00:08,010
Let's start with the main phone operating systems first.

3
00:00:08,160 --> 00:00:14,250
We have iOS on the iPhone and Android they are general use operating systems but we need to mention

4
00:00:14,250 --> 00:00:14,780
them first.

5
00:00:14,790 --> 00:00:19,660
Android an open operating system meaning you're allowed to do more with it.

6
00:00:19,680 --> 00:00:21,800
This isn't good for security.

7
00:00:21,870 --> 00:00:26,370
IOS is a closed restricted system restricting what you can do.

8
00:00:26,430 --> 00:00:28,620
This is good for security.

9
00:00:28,620 --> 00:00:35,490
Android is improving security all the time but iOS from Apple is the clear market leader for secure

10
00:00:35,550 --> 00:00:37,800
mobile operating systems right now.

11
00:00:37,800 --> 00:00:43,680
If you want a general use operating system and security is what you're concerned about the IRS is the

12
00:00:43,680 --> 00:00:45,240
best platform for you.

13
00:00:45,240 --> 00:00:49,550
We cover more on mobile and mobile network security on the course.

14
00:00:49,710 --> 00:00:52,620
But you may also be interested in privacy too.

15
00:00:52,660 --> 00:00:58,730
So there are other security and privacy focused mobile or cellular phone operating system smartphone

16
00:00:58,830 --> 00:01:00,220
operating systems.

17
00:01:00,240 --> 00:01:06,660
There is lineage OS which is a free open source operating system for smartphones and tablets based on

18
00:01:06,660 --> 00:01:09,780
the official releases of Android by Google.

19
00:01:09,780 --> 00:01:14,520
It is the continuation of the Sangean mod project.

20
00:01:14,580 --> 00:01:21,510
There's also selfish OS which is a mobile operating system combining the Linux kernel right particular

21
00:01:21,510 --> 00:01:30,060
hardware platform use the Open Source Merkle middleware and proprietary UI contributed by Djala and

22
00:01:30,090 --> 00:01:32,420
other third party components.

23
00:01:32,430 --> 00:01:37,980
There is also replication an open source operating system based on Android aiming to replace all proprietary

24
00:01:37,980 --> 00:01:44,730
components with free software omni roam free software operating system for smartphones and tablet computers

25
00:01:45,180 --> 00:01:48,960
based on the Android mobile platform micro G.

26
00:01:48,960 --> 00:01:56,220
A project that aims to re-implement the proprietary Google Play services in the Android operating system

27
00:01:56,220 --> 00:01:59,570
with a f l o s s replacement.

28
00:01:59,750 --> 00:02:04,840
Plus if you're not familiar it stands for free or Libera and open source software.

29
00:02:04,950 --> 00:02:12,180
And finally we have pure OS or pure OSS which is also available or will be available on the liberal

30
00:02:12,210 --> 00:02:16,250
5 which is coming from the prism guys which you can see here.

31
00:02:16,410 --> 00:02:22,440
So that's a wrap up of operating systems and how I feel about them in terms of security privacy and

32
00:02:22,500 --> 00:02:23,340
anonymity.

33
00:02:23,430 --> 00:02:31,430
Many of them we will be going into more details on such as tale's Unix cubes iOS Android and so on.
