Components of the iOS Security Model

Device security

Apple’s device security mechanisms help ensure that a user’s device can’t be used by an unauthorized party. The most common device security mechanism is the device’s PIN lock or passcode. Apple allows these locks to be forced on as part of an enterprise policy, or can be set manually by individual users. Enterprises can force a passcode to have a minimum length, alphanumeric composition, complex characters, and even set the maximum age and history policies for a passcode. Users can additionally set the device to automatically wipe itself if the wrong passcode is entered too many times.
