International research has concluded that one of the largest risks to any business now comes from criminal attacks on their technology. The business world is totally dependent on technology, yet in many cases the users of such technology are ignorant of the risks inherent in it. The sheer number of recent 'hacker attacks' and the incidence of Internet viruses demonstrate how prevalent such action is becoming, and how susceptible business is to it. This work is an investigation into all these known technological risk areas and a non-technical evaluation of the problem with numerous real examples of electronic crime and fraud. It also delivers practical, specific advice on how to identify and prevent electronic crime.
