What is SE for Android?
Security Enhancements for Android (SE for Android) prevents apps or processes from accessing data and resources that they are not allowed to. For example, apps outside the Knox container are not allowed to access app data inside the container.
SE for Android provides a Mandatory Access Control (MAC) over traditional Discretionary Access Control (DAC) environments. SE for Android can grant special privileges based specific EMM policies. In DAC environments, since SE for Android controls access of kernel resources, certain apps may not run as intended. Samsung’s MAC feature allows your apps to run properly alongside SE for Android.
