Apple is launching iOS 16 After the new version, it also added a new security update mechanism for the iPhone system called “”Security Response and System File”, mainly to allow iOS updates to quickly and automatically push system vulnerability patches without the need to install an upgraded version.
What is “Security Response and System File” in iPhone Auto Update?
If you upgrade your iPhone device to iOS 16 or a newer version, you will find that the iOS automatic update has more “Install Security Response and System Files” setting, the system will automatically enable this function by default.
Apple’s official description of the “Security Response and System File” function is mainly to control whether the iPhone allows the automatic installation of “Quick Security Response” and “System File” and “Support Accessories” updates. Just restart the iPhone to complete the installation, and you can omit downloading iOS. Update project actions and quickly patch system vulnerabilities in a short period of time。
What is the impact of iOS responses and system files?
Apple adds “Update” to iPhone system updateSecurity Response and System FileThe main purpose of the function switch is to quickly push security fixes in a short period of time when major iOS system security vulnerabilities are encountered. Ordinary iPhone users do not need to wait for iOS updates to fill in the system vulnerabilities. Push security updates easily and faster.
If the user does not enable “Security Response and System File“state,Apple says system profile updates are also automatically installedThis security update feature will make subsequent iOS 16 jailbreak more difficult, and will also cause jailbroken devices to suddenly fail to jailbreak, mainly because security updates will automatically update vulnerable system files, and jailbreak mainly relies on system vulnerabilities To achieve this, Apple now pushes iOS 16 to simultaneously offer a security mechanism to prevent users from jailbreaking.
At the same time, iOS 16 also added a “closed mode” security protection mechanism. This function is also regarded as a defense-level security protection mechanism, which can prevent the iPhone from being subjected to spyware and network attacks.
