Working with technology outside the office brings many challenges. Use of laptops has grown from limited user communities to widespread desktop replacement and broad deployment. The complexity of managing these devices outside the walls of the office is something IT departments have learned to address. Remote connection has extended from fixed location dial-in to wireless on the move, and smart handheld devices such as PDAs have become networked, converging with mobile phones. This larger and more diverse community of mobile users and their devices increases the demands on the IT function which has to secure the device, data and connection to the network, keeping control of corporate assets, while at the same time supporting mobile user productivity.
