An attacker needs only to find a single hole in your defenses, or in any of the frameworks and libraries that you link against, to gain control of your app’s interactions with the system.Īpp Sandbox is designed to confront this scenario head on by letting you describe your app’s intended interactions with the system. The system then grants your app only the access your app needs to get its job done.
If malicious code gains control of a properly sandboxed app, it is left with access to only the files and resources in the app’s sandbox. #EXTERNAL CONTROL APPLICATION FOR HQPLAYER MAC CODE# Take advantage of access throughout your app To successfully adopt App Sandbox, use a different mindset than you might be accustomed to, as suggested in Table 2-1. Partition functionality, then distrust each partĪn app that is not sandboxed has access to all user-accessible system resources-including the built-in camera and microphone, network sockets, printing, and most of the file system. If successfully attacked by malicious code, such an app can behave as a hostile agent with wide-ranging potential to inflict harm. When you enable App Sandbox for your app, you remove all but a minimal set of privileges and then deliberately restore them, one-by-one, using entitlements. An entitlement is a key-value pair that identifies a specific capability, such as the capability to open an outbound network socket. One special entitlement-Enable App Sandboxing-turns on App Sandbox. When you enable sandboxing, Xcode creates a.
