Apple's walled-garden approach to iPhones and iPads -- along with significant enterprise enhancements to its operating system, especially in the latest version iOS 7 -- has been a security nirvana for CIOs. In contrast, Android's open-source environment has been viewed as a breeding ground for malware and risky apps.However, signs now point to a changing of the guard. Samsung, for instance, has become the dominant Android player -- more than 60 percent of the market, according to Localytics -- and has gone on an enterprise offensive with security offerings such as Knox, a containerization technology for Samsung's high-end devices."Many modern Android handsets expose access to a trusted execution engine based on the ARM processor's TrustZone capabilities and this allows app developers to have access to security hardware that is very powerful. Apple may have similar hardware but does not give developers access to it."
