Join Nick Brazzi for an in-depth discussion in this video Note about software versions and jailbreaking, part of Learning iPhone and iPad Security.
- [Instructor] In this movie, I want to start with a quick note about software versions. The information presented in this course is relevant for iPhones, iPads and iPod Touches running iOS version 11. Software can change and evolve significantly over time and iOS is certainly no exception. If you do not know which version of iOS you are running on your device then you should go into Settings and we'll be using Settings a lot in this course. I see the icon for Settings here on my home screen so I'll tap on that.
Next, I'll go to the General category then to About and here, I can see that I am running iOS version 11.2.1 but that first number, the 11, that's all you need to worry about for this course. I also want to mention that you will see the iPhone onscreen for most of this course but iOS works exactly the same on an iPhone, iPad and iPod Touch. There are no different versions between the different devices.
Now, the iPad does have a larger screen so sometimes the layout is a little bit different but that's it. So if I switch over to an iPad, I can still go into Settings. I have the icon here on the home screen, I can tap on that but you'll see the layout is a little bit different. I have a menu on the left side which opens up options on the right side but still, I can go to the options here on the left side, tap on General, that's already selected so on the right side, I see the contents of the General category and still, I can tap on About and I can see which version of iOS I'm running.
So the options are the same as on the iPhone but you see the layout is just a little bit different and that's generally what you should expect if you're watching this course using an iPad. If you are using a device running an older or newer version of iOS, much of the information in this course will not be valid. Now, that does not mean that this course won't be helpful to you. It just means that you need to carefully review each piece of information and confirm whether it works on your device as described in the course. Now, additionally, there is a procedure known as jailbreaking that some people use to unlock iOS devices in order to use non-supported features.
This is not so popular in recent years but it does still exist and I just want to be clear that jailbreaking is not supported by Apple. Doing this compromises the software and can cause it to behave erratically. Furthermore and this is very important, jailbreaking a device will introduce security vulnerabilities that are not covered in this course. To follow the procedures described in this course, you should not be using a jailbroken device. If you have a jailbroken device especially if you're using a non-supported method of downloading apps or if you are using any sort of hacked software then all bets are off when it comes to security.
Neither I nor Apple can help you with security on a jailbroken device and with that in mind, let's dive in and see how we can get our iOS devices more secure.
- Enabling locks on your device
- Creating strong passwords
- Protecting passwords
- Configuring Touch ID and Face ID
- Locating and disabling a lost device
- Adjusting your privacy settings
- Avoiding scams
