Based upon both market trends and device usage on campus, the ISO has opted to specify approved methods for encrypting Apple, Blackberry, and Android based handheld devices.

...

Apple iOS devices

Supported devices include the iPhone (3GS or later), iPad, and iPod Touch (3rd generation or later) only, running iOS 4.x or above.  Earlier versions of the hardware and operating system software do not support key security features, such as hardware encryption.

...

RIM BlackBerry OS devices

Devices using version 4.2 and later of BlackBerry OS are supported.  Earlier versions of the operating system do not support all encryption options, such as encryption of media cards. 

The only approved encryption method for BlackBerry devices is the native content protection.  Content protection will encrypt data the operating system determines to be sensitive, such as emails, contacts, browser cache, and other user data.  Encrypting the contact list will disable incoming caller identification.

To enable content protection:
1. Click Options.
2. Click Security Options.
3. Click General Settings.
4. Set Content Protection to Enabled.

To encrypt media cards:
1. Click Options.
2. Depending upon the version of the OS, click Media Card or click Advanced Options and then click Media Card.
3. Set Encryption Mode to one of the following: Device, Security Password, or Security Password & Device.

Google Android devices

Devices running Android 4.0 (Ice Cream Sandwich) or above for smartphones, Android 3.0 (Honeycomb) or above for tablets are supported. Workarounds exist for some devices running Android 2.3.4 (Gingerbread). Earlier versions of Android do not support native encryption.

The only approved encryption method for Android devices is the native device encryption. Device encryption will encrypt all user data including application data such as emails, contacts, sms and downloaded files. The process to enable encryption will vary based on the version of the operating system installed and the manufacturer of your device, but general steps are provided below.

To enable device encryption:

  1. Make sure you have a lockscreen PIN or password set.
  2. Plug in device charger.
  3. Go to Settings.
  4. Click Security.
  5. Click Encrypt phone.
  6. Read the warnings, then click the Encrypt phone button to start encryption.
