Abstract
Methods and devices for determining whether a mobile device has been compromised. The mobile device has a managed portion of memory and an unmanaged portion of memory, a managed profile and an unmanaged profile, and the managed profile includes files stored in the managed portion of memory and the unmanaged profile includes files stored in the unmanaged portion of memory. The managed profile is governed by a device policy set by a remote administrator. File tree structure information for the unmanaged profile of the mobile device is obtained that details at least a portion of a tree-based structure of folders and files in the unmanaged portion of memory. It is determined from the file tree structure information that the mobile device has been compromised and, based on that determination, an action is taken.
