When a device is used for more than one purpose (e.g., work and personal) there is the potential for information from one environment to migrate inappropriately over into another environment. Therefore it is critical for DoD applications and information be restricted from non-DoD applications and information. In many cases, the presence of non-DoD data on DoD information systems violates either local or department guidelines.
In the context of this IA control, a DoD application is an application that processes DoD data. The characteristics of being distributed through a DoD application store, or digitally signed or repacked by a DoD entity do not by themselves make the application a DoD application. For example, a weather or map application signed and distributed from a DoD application store would not be a DoD application unless the weather, map, or other data was considered DoD data.
The mobile operating system must prevent this occurrence using appropriate technical controls to mitigate the risk of data leakage. The objective is to provide appropriate separation between each environment on the device. |
