Intro to app security for iOS and iPadOS
Unlike other mobile platforms, iOS and iPadOS don’t allow users to install potentially malicious unsigned apps from websites or to run untrusted apps. Instead, (outside the EU) all apps must be downloaded from the App Store, where all apps come from identified developers and must pass automated and human review. At runtime, code signature checks of all executable memory pages are made as pages are loaded to help ensure that an app hasn’t been modified since it was installed or last updated.
After an app is verified to be from an approved source, iOS and iPadOS enforce security measures designed to prevent it from compromising other apps or the rest of the system.
