Apple today published an updated version of its iOS security white paper [PDF] for iOS 12, with information on new features and updates introduced with the iOS 12 software.
According to Apple`s Document Revision History, the updated guide covers iOS 12 features like Siri Suggestions, Siri Shortcuts, the Shortcuts app, Screen Time, Password AutoFill Student ID cards, and more.

On the Shortcuts app, Apple explains that shortcuts can be optionally synced across Apple devices using iCloud or shared with other users. Apple protects against malicious JavaScript within shortcuts by updating malware definitions to identify malicious scripts at run-time.Custom shortcuts can also run user-specified JavaScript on websites in Safari when invoked from the share sheet. In order to protect against malicious JavaScript that, for example, trick the user into running a script on a social media website that harvests their data, updated malware definitions are downloaded to identify malicious scripts at run-time. The first time that a user runs Javascript on a domain, the user is prompted to allow Shortcuts containing javascript to run on the current webpage for that domain.Screen Time, meanwhile uses CloudKit`s end-to-end encryption to protect usage data. Apple only collects Screen Time statistics if iPhone and Apple Watch analytics is turned on, with Apple monitoring whether Screen Time was turned on during Setup Assistant, whether Screen Time is turned on, whether Downtime is enabled, the number of times the `Ask for more` feature is used, and the number of app limits applied.
