Other Protections

iOS Sandboxing

Sandboxing is a security feature in iOS that isolates apps and their associated data from other apps and the core system. This ensures that apps can only access the resources they have been granted permission to use. Each app on iOS is stored within an "app container," which includes the app's executable code, resources, and data. The app container is the primary component of the sandbox environment, restricting the app to access only the files within its container. 

iOS Code-Signing 

Code-signing is a mandatory process in iOS that ensures all apps come from a known and approved source and haven't been tampered with. All executable code must be signed using an Apple-issued certificate. Apps provided with the device, like Mail and Safari, are signed by Apple. Third-party apps must also be validated and signed using an Apple-issued certificate. This extends the concept of chain of trust from the operating system to apps and helps prevent third-party apps from loading unsigned code resources or using self-modifying code. 

iOS provides several built-in privacy and security protections. For instance, setting a strong passcode is the most important thing you can do to safeguard your device. Use of Face ID or Touch ID provides a secure and convenient way to unlock your iPhone, authorize purchases and payments, and sign in to many third-party apps. The Find My feature helps you find your iPhone if it's lost or stolen and prevents anyone else from activating or using your iPhone if it's missing. Stolen Device Protection is a security feature designed to protect against the rare instance when someone has stolen your iPhone and knows your passcode. It prevents the person from performing critical device and Apple ID account operations by requiring biometric authentication with Face ID or Touch ID with no passcode fallback.
