Apple iOS is one of the most popular smartphone operating systems, but it restricts the installation of apps that are not from the Apple App Store. As a result, users often jailbreak their iPhones to defeat this restriction. Jailbroken iPhones are making their way into enterprises that have a Bring Your Own Device (BYOD) policy, but these devices are often barred or restricted by mobile device management software because they pose security risks. This chapter describes the iSecureRing solution that secures mobile apps and preserves the dates and timestamps of events in order to support forensic examinations of jailbroken iPhones. An analysis of the literature reveals that iSecureRing is the first forensicready mobile app security solution for iOS applications that execute in unsecured enterprise environments.
