"A determined data-thief will stop at almost nothing to get their hands on your data. There are lots of tricks that they use to con you or your staff into allowing them access to information that they should not have. It pays to understand some of the tricks that they use, and the sections that follow list just some of the many methods that I have come across.

You should study each method in turn and assure yourself that it would prove difficult to use within your organisation. (See also the discussion of operating systems for information on the relative security of these crucial pieces of software)."
