This question have been toss around for quite some time, depending on how your organization value its data, different company treat the seriousness of data used by employees differently. Organizations such as Banks, Insurance Healthcare and even governments will pay more attention to their data security and the type of devices that was being used by its employees.
This is a real story told by my friend, this happens to his ABC company, his ABC company is into logistics business and mobile devices are widely used especially with the BYOD trend, to his company they never though that they will be the victim of data theft and losses to their business and accounts. The ABC company uses Android based solutions and their employees and managers uses a famous free chat application that they use to create a group chat for employees.
For the past few months customers that have confirm with their services are cancelling at the last minute and shift to their competitors, this have been going on since Jun 2013. An investigation was launch and they found out that there are Malware and applications that was used to exploit the loop hole in the chat application and their Android devices. The competitor uses this to spy on their chat conversation and are able to know which customers they have contract with and perform a counter offer.
ABC company have since stop the free chat usage and insist their employee to install BBM and are now looking into getting BlackBerry BES 10 for their company. My friend contacted me on this and i have shown him my BlackBerry device which he tested it and found that it is suitable for his company needs. He told me the main thing they need now is a secure messaging system, GPS, email, and a secure workspace to separate their employee personal and work related apps.
So beware of what applications that you install in your mobile phones. For those Organization that feel that mobile security is not important think again, your employee could be an unknowing victim of a hacker or have install Malware in his device and your company could be losing confidential information to hackers or your competitors.
