越獄（越獄）

越獄是指消除對(duì) iOS 設(shè)備施加的所有限制的過程。它允許 root 訪問系統(tǒng)文件，這些文件可以被操縱以安裝 Apple 不支持的應(yīng)用程序、主題和擴(kuò)展。iOS 設(shè)備用戶越獄他們的智能手機(jī)和平板電腦以下載未經(jīng)批準(zhǔn)的程序，例如宗教應(yīng)用程序、調(diào)整和用戶界面自定義應(yīng)用程序。越獄 iOS 設(shè)備對(duì)設(shè)備和用戶構(gòu)成了許多安全威脅。越獄的智能手機(jī)很容易受到惡意軟件和木馬的影響，這些惡意軟件和木馬會(huì)對(duì)系統(tǒng)文件造成巨大破壞。黑客可以輕松地在越獄設(shè)備上安裝跟蹤程序，以竊取用戶的重要文件和信息。

越獄允許用戶控制其設(shè)備的根和媒體分區(qū)。這是所有 iOS 文件的存儲(chǔ)位置。不受限制的越獄是無需使用計(jì)算機(jī)即可實(shí)現(xiàn)越獄的過程。當(dāng)用戶關(guān)閉并重新打開設(shè)備時(shí)，設(shè)備會(huì)完全啟動(dòng)，并且無需計(jì)算機(jī)即可修補(bǔ)內(nèi)核。對(duì)于系留越獄，每次重新啟動(dòng)時(shí)都需要計(jì)算機(jī)來打開設(shè)備。如果設(shè)備自行啟動(dòng)備份，它將不再有打補(bǔ)丁的內(nèi)核，并且可能會(huì)卡在部分啟動(dòng)狀態(tài)。

Jailbroken (Jailbreak)

Jailbreaking refers to the process of removing all restrictions imposed on an iOS device. It allows root access to system files that can be manipulated to enable installation of apps, themes, and extensions that are not supported by Apple. iOS device users jailbreak their smartphones and tablets to download unapproved programs, such as religious apps, tweaks, and user-interface customization apps. Jailbreaking iOS devices poses many security threats to the device and the user. A jailbroken smartphone can easily be affected by malware and Trojans that can cause great damage to the system files. Hackers can easily install a tracking program on a jailbroken device to steal important files and information from a user.

Jailbreak allows the user to get control over the root and media partition of their device. This is where all the iOS files are stores. An untethered jailbreak is a process where a jailbreak is achieved without the need to use a computer. As the user turns the device off and back on, the device starts up completely, and the kernel is patched without the necessity of a computer. With a tethered jailbreak, a computer is needed to turn the device on each time it is rebooted. If the device starts back up on its own, it will no longer have a patched kernel, and it may get stuck in a partially started state.
