Tools for managing and securing tablets in the enterprise

Whether it is a tablet, laptop, desktop, or whatever. Your biggest security problem is the "loose nut behind the keyboard". A well written policy, shored up with some quality training, stands a good chance of getting the users in line with what you are trying to do. Otherwise, nothing you implement will work for very long. BTW, I have found the greatest success with a training approach that enlists the users help, rather than "here's how you will be punished if you fail to comply".
