An interesting viewpoint:

The definition of Human Error is 'a mistake made by a person rather than being caused by a poorly designed process or the malfunctioning of a machine such as a computer'
Human error continues to be the primary cause of information technology (IT) security breaches. In fact, the UK Government has faced repeated embarrassments over lost data, with over 270 data breaches being reported over the past year alone. Prime Minister Gordon Brown recently stated that the government cannot promise the safety of personal data entrusted by the public, citing human error as the reason, so thatís okay then isnít it? Of course itís not.
