| Application functionality is typically broken down into modules that perform various tasks or roles. Examples of non-privileged application functionality include, but are not limited to, application modules written for displaying data or printing reports. Application security functionality that performs security tasks such as enforcing access and information flow control requires additional system privilege and can have a large impact on the security of the application and its data. Rather than allowing the entire application access to this security functionality, application developers must isolate these critical functions from non-privileged application functions and other security functions.
Rationale for non-applicability:
It is assumed that mobile applications leverage the security functions of the operating system and that the operating system provides the requisite isolation of security functions from other functions. If an application embeds additional security functionality, those security functions are protected from other applications via applications sandboxing. When the mobile application connects to remote enterprise application resources, the remote resources perform the required isolation. |
