While dual persona goes a long way to addressing the security concerns of IT departments - many of which balk at the at the idea of supporting devices that run both enterprise and consumer applications - Rob Walker, partner at Ernst & Young, warned that there are still grey areas around liability.

This means that the HR, Finance and IT departments all need to be involved in defining the policies around BYOD within an organisation, he said.

IDC analyst Mike Cansfield added that many people are still very distrustful of BYOD, because they do not want business to encroach on their personal lives. This is particularly true among older employees, who are less attuned to new flexible and collaborative ways of working.

Furthermore, the financial benefits of BYOD are yet to be proven. While a company may save money by not buying hundreds of handsets, this could be outweighed by the cost of implementing mobile device management (MDM) software that supports multiple platforms.

As a result, some organisations are now adopting a "choose-your-own-device" (CYOD) strategy, meaning that the company supports a limited range of devices and employees can make a choice from within that catalogue.
