If apps can communicate with third parties in an uncontrolled manner, this can create communication channels that an organisation may be unable to identify and monitor. For example, a user could transfer information from an end device to the outside world through a cloud data storage app. The close integration between many apps and social media services also makes it difficult to check whether and how information leaves an end device. These types of communication channels are very hard to trace. This can cause even more problems, such as when a user or organisation is required to archive information or processes.
