Apple iOS Security Checklist

Supported devices include the iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5,  iPad, iPad2, and iPod Touch (3rd generation or later) only, running iOS 4.x or later.  Earlier versions of the hardware and operating system software do not support key security features, such as hardware encryption.

  1. Update firmware to the latest version.  Apple iOS devices ship with the most current version of the firmware available when the device was manufactured, but new updates often address security vulnerabilities in addition to bug fixes and new features.
  2. Require a Passcode
    1. Tap Settings.
    2. Tap General.
    3. Tap Passcode Lock.
    4. Tap in a passcode.  The passcode must be at least 4 characters in length.
    5. Tap in the same passcode.
  3. Set auto-lock timeout
    1. Tap Settings.
    2. Tap General.
    3. Tap Auto-Lock.
    4. Tap “1 Minute” or one of the other values.  Lower values are more secure.
  4. Disable grace period for lock.  The grace period allows the device to be unlocked after auto-locking without providing an unlock code.  A value of “immediately” will fix this by requiring the passcode to be entered regardless of when the device was last lock.
    1. Tap Settings.
    2. Tap General.
    3. Tap Passcode Lock.
    4. Tap Require Passcode.
    5. Tap Immediately.
  5. Enable Fraud Warning in Safari.  Fraud warning in Safari helps protect users from visiting potentially fraudulent Internet sites.  If a user navigates to a known fraudulent site covered by this service, Safari will not load the site and instead display a warning to the user about its suspect nature.
    1. Tap Settings.
    2. Tap Safari.
    3. Turn on Fraud Warning.

Digital certificates are offered to faculty and staff as a tool for enabling encryption technologies as well as for signing of email and other important electronic documents. Because it offers the reliability of central management, you can be assured that certificates can be recovered and revoked in the event of loss or tampering. Two primary uses for certificates are to encrypt email and data files and to sign email.

Once you have completed the iOS security checklist, please follow these instructions to encrypt your e-mails.
