The increasing complexity of mobile devices, such as the soon-to-be-launched "must-have" iPhone, poses a growing security headache to employers.

The technical advancements of such gadgetry allow vast amounts of data to be downloaded and stored. In the light of various high-profile stories of data theft, devices like the iPhone only make it easier and quicker for those with malicious intent to commit an "inside job" - and it's virtually untraceable. These devices could potentially be used to carry thousands of documents out of the office, or even to release a virus onto the corporate network.

Following the news of the launch, companies need to ensure that they are agile in the way they protect the network, making sure IT security standards are always one step ahead.
