Book excerpt: Information and Communication Technology (ICT) is becoming indispensable in the spheres of business, government, education and entertainment. It makes Internet marketing, e-government, e-learning and online chat services possible. And its commercial aspect, e-commerce, is part of this trend. Today, no business training is complete without the inclusion of at least the basics of e-commerce. But although e-commerce has opened up new opportunities, it also presents threats and risks. The success of e-commerce hinges on security and trust. Every business manager should therefore have a fundamental awareness of the meaning of e-commerce and ICT security and risk management. This second edition provides guidelines for overcoming these challenges by exploring the ways in which entrepreneurs and managers should co-operate with IT experts to exploit opportunities and combat the threats imposed by new technologies.
