Technology is revolutionising business and society. While you can easily judge how much a factory is worth, some of your company's most important assets may be the intangible ones. The real worth of your company is a matter of its intellectual capital as well as the sites and machinery in its possession. In today's world, the ownership of information – patents, designs, databases – is more important than ever. This kind of information is held on computer systems. So your company needs to be as serious about protecting its digital information from industrial espionage and cybercrime as it is about protecting its warehouses from robbery and arson.
