Jeremy Allen of Intrepidus, leading provider of mobile applications and device security services, explains why a jailbroken iPhone creates a security threat for Enterprise IT:
“When jailbreaking and or rooting a [mobile] device, the goal is to circumvent or disable the pieces of the OS and platform that keep applications in a sandbox and running with limited privileges.
These devices could be difficult, or even impossible, to enforce security policy on as the user can trivially circumvent the policy enforcement without the management servers being aware of it.”
MDM vendors such as Good Technology, MobileIron and Sybase claim that they can still detect if the iDevice is jailbroken without the Jailbreak Detection API. However, Allen cautions that these methods are not foolproof.
It’s not clear why Apple decided to remove or disable the API in iOS 4.2.1 and has declined to comment on it.
