I've just come across an interesting piece on the BCS web site when Martin Allen is advocating that all employees in the organisation should employ encryption when copying data onto a mobile device, whatever that may be (not just the notebook or PDA, but also the USB stick or MP3 player). Those of us in corporate IT have a huge educational challenge in front of us to get the message across about data security. IMHO encryption tools are going to have to become as ubiquitous as anti virus software...
