Apple designed the iOS platform with security at its core. When we set out to create the best possible mobile OS we drew from decades of experience to build an entirely new architecture. We thought about the security hazards of the desktop environment and established a new approach to security in the design of iOS. We developed and incorporated innovative features that tighten mobile security and protect the entire system by default. As a result iOS is a major leap forward in OS security. Every iOS device combines software hardware and services designed to work together for maximum security and a transparent user experience. iOS protects not only the device and its data at rest but the entire ecosystem including everything users do locally on networks and with key Internet services. iOS and iOS devices .
