Exploring the use of iPads and mobile devices in education.
1. Set your iPad to erase all data after failed passcode attempts: You can set your iPad to erase all data after ten failed passcode entry attempts. Just go to Settings, General, Passcode Lock and check the Erase Data option.
2. Encrypt your data backups: Don't forget that your data can also be stolen from the desktop you use to synchronize and backup your data. You can however encrypt your iPad's backup data from within iTunes. Open the iPad in iTunes, click the Summary tab, and check Encrypt iPad backup under the Options heading.
3. Use your passcode effectively: iOS defaults to a four-number passcode, but you can turn it off by going to Settings, General, Passcode Lock, Simple Passcode. Now you can use any full keyboard password to lock the iPad. The password also helps to encrypt your mail and attachments on the iPad, so you probably want to make it safer than a four-digit number.
