What I have found that most people when they get rid of their devices they neglect to erase or wipe the device clean of their personal information (files, pictures, contacts, messages, etc…). The National Cyber Security Centre, UK’s independent authority on cybersecurity, has a nice tech writeup on resetting (wiping clean) and reprovisioning your iOS, Android and Windows Devices (see source link below).
For each platform, the most useful restore methods are explained in full, alongside the risks of using them. We then recommend one of the methods to use for the following four common scenarios:
- Scenario 1: Sanitising a device believed to be compromised with malware
- Scenario 2: Preparing a device which has not previously been managed
- Scenario 3: Reissuing a device to a different user in the same security environment
- Scenario 4: Sanitising a device for release to lower security domain or sale
