Apple offers the sandbox on iOS for performing each
app. Sandbox of Apple uses the approach "One size fits all" to control and access app. This way means all sandboxes
have the same resources and functionalities. For example, each app cannot access and read other apps' files. For Android which also uses sandbox and its approach is app specific. During installation, apps require the users' permissions for implementation. Users also can agree or reject these permissions. After rejecting them, the apps will be ignored. This kind of sandbox has a advantage which can be customized for each application instead of Apple's one-size-fits-all. The disadvantage is that this approach compels the users to make the security decisions, which history has shown isn't a good method.
