-
Resource Restriction
App sandboxing restricts an application’s access to system resources such as the file system, network interfaces, and hardware components. An application confined within a sandbox cannot directly access files belonging to other applications or modify critical system settings. For example, a game application would be prevented from accessing a user’s contact list without explicit permission. This limitation is crucial in preventing data theft and maintaining system integrity, directly contributing to system safety.
-
Data Isolation
Data isolation ensures that each application operates within its own private data container. This container safeguards application-specific data from unauthorized access by other applications. Should one application become compromised, the attacker’s access is limited to the application’s sandbox, preventing them from accessing sensitive data stored by other applications. In practice, this isolation mitigates the risk of cross-application data breaches, a common attack vector in less secure environments, and enhances system security.
-
Privilege Minimization
Privilege minimization dictates that applications should only be granted the minimum set of privileges required for their intended function.
