Join Nick Brazzi for an in-depth discussion in this video Note about software versions and jailbreaking, part of Learning iPhone and iPad Security.
- This is a quick note about software versions before we get started. The information presented in this course is relevant for iPhones, iPads, and iPod touches running iOS version 8. Now software can change and evolve significantly over time, and iOS is certainly no exception. If you are using a device running an older version of iOS, much of the information in this course will not be valid. Now that doesn't mean that this course won't help 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 this course.
Now additionally, there is this procedure known as "jailbreaking" that some people use to unlock iOS devices in order to use non-supported features. 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're using any sort of hacked software, all bets are off when it comes to security. Neither I nor Apple can help you with security on a jailbroken device. With that in mind, let's dive in and see how we can get our iOS devices more secure.
- Protecting passwords
- Keeping iOS and apps up to date
- Enabling locks
- Locating and disabling a lost device
- Adjusting app privacy permissions
- Installing malware-free apps
- Erasing a device—or preventing it from being erased
